New intake for crossfire = more HP!!!!

[nelson84]

On Chevy small block heads some of the bolt holes for the intake extend into the rocker area which is oiled. Your trying to keep this oil from seeping up the treads. I clean the bolt holes with mineral spirits on a Q-tip and use Permatex High Temperature Thread Sealant (PX #59214) on each bolt to the head. I apply a bead down one side and then use the tip of the tube to push the bead around the bolt so that the threads are lightly wetted all around.

I'd spread a thin layer of rtv on both sides of the gasket. Part of the reason for the rtv is really just to hold the gasket in place as you install the intake.

Thanks dude, I will do that both sides of the gasket, And I will put some sealant on the bolts. And "the right stuff" on the china rail. Then we can get some testing done to see if this intake manifold makes a difference.:confused

I would think that the Renegade guys would be the source for that info. A little post sales follow-up from the guys that created it. They should know and be willing to answer all your questions.

Instructions are included on our website in PDF format. There is also a sheet of paper with each manifold that shows how to get them in the "How to" section.

 

[Buccaneer]

If you read the NOTE on page two of our "Instructions" it says...

NOTE: PLEASE study these guidelines carefully before attempting this installation. This
removal and installation can be accomplished with common hand tools (with the exception
of torque and fitting/line wrenches) and good mechanic practices. However, you should be
familiar with and be comfortable working on your vehicle. If you do not feel comfortable
performing this removal and installation process, it is highly recommended to have the
installation process completed by a qualified automotive mechanic or a reputable
automotive shop.

These "Instructions" were written with the assumption that you as the installer have done this task before and you really shouldn't have to ask questions on how to do this task, but rather just see if there is anything that you really need to be aware of that may be special, that’s all.

We DID NOT make this a highly comprehensive instruction manual, just a reference. If you need more guidance, see the GM Service Manual or qualified mechanic.

If you also look just below that NOTE mentioned above you'll also see this and I think it says it all...

CAUTION: It is assumed that the installer is familiar with engine maintenance and is
knowledgeable about general automotive safety practices. If unsure what these practices
entail, consult the GM Service Manual for details and precautions associated with engine
maintenance and associated dangers. DCS will NOT be responsible for any personal injury
or any automotive damages in any way associated with improper maintenance practices.

I got around to installing it today, everything went well and it started right up. I have to adjust the timing a little but other than that it runs great.
I have the following from DCS:
renegade intake manifold
2 inch TB's
adjustable fuel pressure gauge( I set it at 14.5 psi)

Just an FYI, it appears that you have an 84 and you are using an 82 FP assembly it will fit either one. However, if you are using an 84 aircleaner it "may" not work correctly for you, the correct FPA works fine for an 84 motor. Are you running an A.I.R. pump delete? Try running 13psi first with those larger TBs and adjust the timing above 6* You should be able to go to 12*, but this is where a dyno comes in handy to see what the motor likes and max power gain. Try 8-10* and see if its ok with that, if not, back it off 1* at a time. BTW, we don't recommend running a 2" TB on a stock motor, I'll be curious to see how yours runs.

 

[nelson84]

Okay I will try 13 psi and 10 degrees.

When I put the TB's on it was just dumping the fuel in, my stock pump was pushing well over 15 psi, I backed it off to 14.5 it seemed to run better with less fuel pressure. I have not drove it yet I need to get some insurance for this old vette. Where I live they make you pay your speeding tickets before they will give you insurance, this is going to be an expensive Monday. I need to get my hands on a timing light.

 

[ex-x-fire]

Good job on getting it running. Make sure you change your oil/filter, you don't want to run it too long if any coolant or debris fell down in the motor.

Thanks dude, will change the oil. I just have to set the timing and this old crossfire will be good to go.

I adjusted the fuel pressure gauge by turning it down slightly now the air box cover fits fine. I am not sure, but does the renegade sit a little higher than the stock intake? I put a new rubber seal inside the air box cover maybe that is making it sit a little higher, I do have a 1/4 of an inch of room between the hood and the crossfire.

I set the fuel pressure to 14.5 psi and the timing to 10 degrees. I will get this thing off the casters and on the road to give you guys some 0-60 and 1/4 mile times. I have a feeling there will be a major improvement, it seems to start quicker and run smoother, even sounds better, might be due to the timing???

RENEGADE!!!

The Renegade was manufactured to fit under a 84 hood due to the tight nature of the airbox. There are machining tolerances to contend with but you should be fine.

So, in layman terms, without the euphemism(s), the renegade is not the same dimensions as the OE manifold?

I would hope not! If so it would suck just as bad.

Nope. But everything is where is should be as far as TB placement and and bracketry is concerned. The bonus is you can close the hood on a 84 Vette. 82 Vette's and F-Body vehicles have more clearance than 84 Vette's.

FWIW - The overall plenum volume is around 20% larger.

 

[nelson84]

With the new gasket in the airbox and new gaskets on the TB's between the air box and the TB's made it about a 1/4 inch taller, I will tighten them down futher as they get set in.

 

[Curious George]

I would hope not as well. What I was getting at in my poorly referenced question was that "critical" dimensions were not changed and the additional volume was being taken up in non-essential space that would not hinder a "direct bolt in" fit.

I was "cornfused" by the euphemisms...

[nelson84]

So any other renegade projects?

 

[nelson84]

Timing issue, I set the timing to 8 degrees beforeTDC with the est wire off, and when I hook the est wire back up the engine runs at about 18 before TDC. What should it run at when you hook up the est? The same at 8 degrees or higher?

Having a little trouble with the timing, I want to get out there and do some testing 0-60 and 1/4 of this renegade.

Anybody have any ideas?

 

[ex-x-fire]

Yeah, thats normal. W/ the est wire unhooked thats base timing, like on an old car w/ a vacuum advance distributor you have to unhook the vacuum line to set the timing properly. Just make sure the timing advances when you rev it (w/ the est wire hooked up), it should go off the scale as you rev it.

 

[nelson84]

I got the timing fixed, I think DCS should have put a pack of cigarettes in the box, I feel like I need one after that test drive.

Are you saying "I picked a bad day to quit(insert- sniffing glue, smoking, drinking, ect)":confused
