Halltech T1C Intake on my 2001 Z06

[P51Aviator]

Mods, eh?

I just installed a Halltech T1C intake to my 2001 TR Z06. What a world of difference!!!

While I was at it I scrapped the screen on the MAF. Pretty noticeable power increase. Haven't had it on the dyno yet, but my last trip when it was stock yielded 336 rwhp/rwtq. Hopefully I'm at about 345 at the rear with this mod, and on the way to 400.

Here is a link to the installation photos if anybody is interested: http://proxy.ca.abydos.com/gallery/exe/album24

Congratulations on a very good mod. I probably wouldn't remove the screen off the Maf but thats just me. Your probably making more power that way.

Good luck

JB


BTW..cool photo!

 

[P51Aviator]

Thanks! I'm really happy with it!

I found out that Chevy eliminated the screen in the 02's, so I was comfortable pulling it. If you look at a pic of an '01 with the screen removed and an '02 MAF, they are identical. As I understand it, the screen was to smooth out airflow into the MAF, and a carryover from other GM cars/trucks with extreme curves in the air intake pieces.

A cool by-product of this mod: My 1-4 shift light hardly ever comes on anymore. Don't know why, but it saved me getting the CAGS eliminator!

 

[JBsC5]

I added a ported and polished throttle body..Cost was only 169 dollars and its a mod I would throughly recommend as well.

I never believed in this TB mod till the guys over at z06vette.com were going on and on about it.

A very high quality piece and the transformation of refinement was very impressive.

Heres the contact if down the road you decide you want this..

Probably about 40 minutes for the install.

Goes nicely with the air intake mod imho..

 

[P51Aviator]

Thanks! I've heard really good things about the Shaner mod as well on the Z06 forum.

I noticed you have the FLP long tubes. Looks like I'm heading down a similar road as you; I am ordering my system from LAPD on Monday. Did you do the install? What did you notice performance wise following the install? I'm going to run the FLP's into my stock Z06 exhaust first, and assess if I want to go aftermarket. I don't want the car to be too loud, but the Corsa system has had my eye for some time!

 

[c4c5specialist]

HI there,
I personally did the installation of the FLP on JBs car. The preliminary issue was only the air injection tube fittings, which did NOT fit perfectly.
Information I have now, is that this has been rectified, and the o2 sensor fittings are in a more easy location behind the converters.
Installation, will take about 4 hours, on a lift.
Just remember, your 02 will NOT see the same power gains as JBs 01, due to his having precats.
If installed correctly, you will not set codes, and will be EPA legal for emissions.
I personally like the system and the ease of installation.
Allthebest, c4c5

 

[P51Aviator]

I can live with 4 hours! I have an 01 actually, not an 02, so hopefully I'll see some of the same gains that JB saw! I dyno'd it a few weeks ago, and got 336 hp and 336 rwtq (std) at the wheels in stock configuration. I'm going to check it again with the Halltech installed, then again with the exhaust in place.

Nice to hear it will be EPA legal - I was a bit concerned with that. Thought I might be going down a 'track only' road!

Was the exhaust sound considerably louder after the FLP installation? Any resonance issues in the car after the install?

Thanks for the info on the air injector tube issue. I'll check on that Monday.

 

[JBsC5]

The headers are very nice. There is no resonance what so ever. The sound is very much stock, maybe just a little bit louder at idle..but very little and then..when you drive past 4000 rpm its like music to your ears..and thats with the stock titanium.

I half thought about going for an aftermarket exhaust but thought to myself..I don't want to add weight..and the corsas are even heavier than stock..although they sound totally cool.

I've heard my friends cars with the FLP's with the touring exhaust and it would probably be my choice..(I've come very close to buying a set and the jury's still out but I'm holding off..) and I have heard the indys with the tpis and they sounded goo too..and then...I've also thought about the titanium corsas but the cost is kind of high and I'm really very pleased with the setup that I am running now. So thats where i'm at for the moment..

Overall..

Really a great mod. I almost did a dyno prior to installing the headers and in fact was offered to have my car dyno'd for free.. but b/c my car was such a high oil consumption user I didn't think it would be an accurate comparision of before and after mods..and then the motor was like new after re ring..

so if its ok..I'll borrow that 336rwhp as a baseline myself incase I ever get my butt over to a dyno..I figure the average numbers I'm seeing on a stock 2001 Z06 is between 330 and 340 rwhp depending on dyno ..that numbers right on target..

IF logic prevails..15 rwhp for intake and 15 for the headers/xpipe and high flow cats sounds about right..and not too aggressive.

People have quoted dyno improvements on intakes up to 17.6 rwhp (from manufacturer/Jim Hall) and the people on the net who threw on flp headers talk about improvements ranging from 18rwhp to 22rwhp..

So I believe my estimates on improvements should be accurate if not conservative. (by a few ponies)

I don't believe the throttle body(Choose what brand you like..I did some research though on the Z06 site and the guys overwhelming suggested Shaner so I went with it) will give that much of an increase in peak hp if at all.. but I truly beleive it is one of the best mods..the improvement in hp and torque below the peak where we do most of our driving and thoughout the entire rev band is the beauty of this mod..

I was never a believer of throttle body mods..but after installing this product which costs all of 169 dollars..its one of my favorites..

Good luck on the dyno..Good luck on whatever you choose and let us know the scoop as you make your choices.

Dyno with coolant below 192 and oil temp above 210 if you can as a standard..

You might want to throw in a vinci or whatever brand you choose 178 degree thermostat..its pretty cool at keeping the car below 192 degrees but usually runs around 187..which is something I consider the best temperature..

At sustaned idles..I just throw the airconditioner on..full blast with the interior temperture set around 80 degrees and the car stays right at 192 degrees tops..

I hope this helps gives some insight.

 

[P51Aviator]

Thanks!!!! That seals it. I'm sticking with the FLP's and stock exhaust for now - I agree with you on the weight; I don't think it's a great trade. I'm totally hooked on the Corsa's but with all the pipe included with the FLP's, I hate to cut up the Corsa TI system to make it work. Total waste of money. Corsa should get smart and make a TI system that is just the back portion.

I'm also adding a DRM 4pt rollbar (ordered), 5pt harness (Teamtech - ordered), Hurst shifter, steel braided brake lines and Dot-4 fluid change, CAGS defeat, thinking about the Shaner S2 and possibly a trip to Halltech for a dyno tune, and that will do it for a while. Wouldn't mind picking up some CCW rims and some Hoosiers for the track, but that will have to wait.

Here is the jpg from my Dyno for your reference. http://members.cox.net/p51aviator/p51dyno1.jpg

I didn't know any better at the time, and got a STD dyno instead of an SAE. Some people are tweaking about it, but it's still a baseline to me. The SAE numbers would be a bit lower, but considering the dyno was in the back of this guys shop and it was hot as hell - no fans, I'm running with the STD numbers as pretty accurate whether SAE or not! Next trip I'll pull STD and SAE at the same time so I can level it and convert this STD dyno to SAE for the skeptics (and my own peace of mind).

I'm going to dyno at each mod - trip to the dyno this week to eval the Halltech T1C installation, then another after the headers are in. I'll post them to my site and put the links here when I get it done.

 

[JBsC5]

Cool! Its great to hear you so enthusiastic about your car..

I think what your saying with regards to the dyno is right on the money..Your in the zone on that..

Wow!

As far as heading over to Jim Halls place..do me a personal favor and tell him JBsC5 out in Jersey says hello..Jims a top notch guy..I've always respected him. A really nice man and his pursuit to fine products always made my C5 do the hustle down at englishtown raceway..

I don't know for sure but Jim used to make a ported throttle body ..I looked at his internet site to buy one b/f I bought the shaner and couldn't find it. So I bought the shaner..

I might suggest..asking him if he has one of his ported and polished throttle bodies on hand and considering throwing it on your car...(JMO) You might like it better than the shaner..?

Remember..


TB's don't effect peak power that much but its a kick @SS mod..Theres so much more to be concerned with than peak power..sometimes its the entire improvement in the power curve and its shape that important..Just a thought ..

The labor is like 40 minutes I bet tops to throw one on..

Think about it and have fun!

The one additional step you need is to get cold air to the Halltech from under the car. You are ingesting the warm air from the engine compartment after the engine gets warmed up.

 

[JBsC5]

Panzer has a point..cold air intakes such as the Halltech..or whatever brand you choose do quite possibly offer more on the road hp..


I thought about this myself before I choose an air intake. on my car......and then decided the z06 grills should offer some degree of cooler air to the intake.

The ease of installation on the halltech t1-c just cinched the deal for me. (20 minutes) since it places the big halltech filter where cooler outside air can get to the filter..

Is it as much cool air as the Tric cold air induction I had on my 1999 C5 that had a sealed foglighted area as all standard c5's have....? Most probably not but ..

I wanted the ...20 minute install, the price was right at three and change at the time ...the car had the zo6 grills on it from the factory and I figured I'd add other mods like headers and what not that would have incremental effects as well.

In the end I'm very pleased with what I have..

I hope this helps.

Panzers right though..if you want the absolute fastest intake where that extra tenth counts...cold air does rule!

Jim had talked about offering a t1-c convertible version for track use since so many guys had concerns over water and cold air.

Don't know if he ever made that quick change piece he discussed.

Ask him while your there if you would..just for kicks.

 

[P51Aviator]

Can't I duct air from the vents in front to the compartment that the Halltech filter lives in? The area in front of the radiator?

 

[Cali]

did you say Hurst?

I see you added a Hurst to your buy list...

I thought I saw a twinkle in your eye after trying mine
Glad I could be the devil on the shoulder... of course now I have to buy headers!

btw: me and Ken did a 45 in 3rd roll on to 100... I pulled him, not a lot, but probably 1 car. I shifted earlier than he did so that messed it up.....

 

[JBsC5]

I think the z06 grills (specifically on the drivers side throw some air into the Halltech T1-C..its enough for me)

I wouldn't advise doing any other work with it.

I might be getting old but that extra cooling for 10 degrees of lower air intake temperature just seems not to be worth it for me.

With the car moving GM thought with the stock air box installed that the car was getting cooler air. With the big Halltech filter sitting right over there..it should be somewhat better then the center mounted relatively closed stock air box.

I would suggest moving on to another type of mod after installing the Halltech t1-c..but please note thats just my opinion.

Hope this aids in whatever you decide.

Have a good one.

BTW..the Hurst needs I guess 500 to a thousand miles to be broken in ..first installed its a little stiff but as the miles rolled on..I can't remember the exact number of miles but now..I can shift the thing with one finger up and down all the gears..

Hey dude! Ya found the place, eh? I was hurting when z06vette went down - but I've been seeing some of the crew popping up over here lately. I guess they got hit with a denial of service attack....bummer!

Yup - the Hurst is rockin, and officially on my list!!! Headers are in the back of the Expedition, and awaiting a trip to the mechanic's shop. I found a guy locally that is an incredibly recommended mechanic for racer guys. He primarily works on Vipers, but is going to be working on more Vettes. Referral basis only right now, so I was lucky to get in with him. He's a great guy! (He's the guy that supercharged my friend Larry's Viper!)

Anyway - went shopping again today in preparation for Friday's Buttonwillow event.

Brey-Krauss harness bar - arriving Thursday
Team Tech 5pt Harness - picking up Thursday

Here is my Thursday night:

1. Install steel braided brake lines and replace fluid
2. Install harness bar
3. Install Team Tech harness
4. Load the car on the trailer
5. Try to sleep cuz I'm goin' racing on Friday!!!

I'm still considering the DRM rollbar, but will see how this SCCA approved harness bar works for now.

You bring up a good point with respect to the original design of the airbox location. I agree that the effort to bring colder air to the Halltech location isn't worth it.

Headers are going in next week, so I'll be busy playing with that and tuning for a while!

Good to hear about the Hurst. Cali has one in his Vette he let me try last weekend. WOW!!! I was hooked out of the gate. The difference between Hurst and stock is absolutely incredible, and totally worth the money, to me! That will be next (same time as headers).

Damn this is fun!!! Damn this is addictive!!!!!!

Take care - I'll keep you posted on the dyno numbers. I'll be hitting the dyno on Friday to see what the Halltech did for me.

 

[Cali]

Hey P51,
Your Thursday schedule is making it really hard for me to go to work right now... which i have to do.. (sigh)

You know you really should pace yourself, just like crack your addition will get more expensive as you will have bought all the reasonablly priced mods... if you tell me you are selling your other car to get a supercharger... I'm gonna have to call for an intervention!

[P51Aviator]

Well, work intervened on my Thursday plans, and I didn't get SQUAT done!!!

I did manage to get the Brey-Krauss harness bar installed tonite, and only the shoulder harness in. I didn't buy the hardware for the lap belt and submarine belt from LAPD when I got the harness bar, so I'll be ripping my seats out tomorrow at the track to address that little issue....freaking Chevy didn't put mounts in like the Viper guys get... I did get some bolts with the harness that I can fab in tomorrow at the track Should only take about 30 minutes if I do it right.

The Team Tech's look cool as heck - I'll post a pic when I can.

I'll be on the track and dyno tomorrow. I'm bringing the camera, but don't have a mount on the harness bar - I'll see if I can fab something tomorrow to capture some footage of Buttonwillow.

Later...

Looking foward to hearing of your success.
