If by that you mean folks will continue to ask for more than "he said he saw an increase of 30RWHP", I suspect you're correct.POST DELETED BY OWNER... I can see where these posts will end up going, so I deleted my posts/comments.
Once again, folks involved with the Renegade intake manifold appear unable to supply credible test data.Owners of stock or near stock 82s or 84s with the L83 need to remember...buyer beware. It is my opinion that the Renegade may add some power at high rpm, but it's also my opinion that its effect on the rest of the torque curve is at least unknown and perhaps questionable.That said, in looking at "Buccaneer's" sig line, the engine in his 82, which might have played a part in the Renegade's development, is highly modified. In addition to having some pretty serious valve train enhancements, the engine is a 383 rather than a 350 and it's got much better heads and higher compression. Typically, a displacement increase coupled with the those mods will "see" an intake manifold port volume increase much differently than will a smaller, less modified engine (ie: a stock or near stock L83). There's little question in my mind that a Renegade intake on a highly modified L83 would work pretty well and have a reasonably flat torque curve, but...The most common "question" in this and other "Renegade Threads" has asked about how it works on a stock or near stock engine. When that question is posed, as best I can determine, little more than unsubstantiated boasting is been the response. Time after time, those contributing to this and other "Renegade threads" have asked those advocating the Renegade ("nelson84", "Buccanneer" and a few others) for some test data. Time after time the vast majority of what's been posted in response seems to me to be the proverbial "smoke and mirrors". Granted, once or twice we've heard some round numbers describing increases in peak power, but the fact remains, we've never seen results from an A-B engine dyno or chassis dyno test which shows the before and after power and torque curves.So, again, if you have a stock or mildly modifed 82 or 84 Crossfire motor, my advice is to take what you may "hear" about the Renegade with a grain of salt until someone posts some unbiased, comprehensive test data.On the other hand, if you've got an 82 or 84 which has an engine which is significantly modifed and you want to retain the 2xTBI set-up, the Renegade might be a suitable alternative to the stock intake manifold.
Does small run quantities, changes, setup costs, and budget constraints have anything to do with the unavailability or is it just backlog?You can't get a renegade right away because there is such a line up to get one it will be awhile. Anything that will help a crossfire is worth a try.
How would I Know I am just a customer that has a renegade that now runs high 13's instead of high 14's. My 84 is faster now with the renegade that is all that matters to me.Does small run quantities, changes, setup costs, and budget constraints have anything to do with the unavailability or is it just backlog?

I also own an 85 TPI and my 84 with the renegade will pull away from it. I have switched drivers when racing the two vettes and same results. I prefer the crossfire over the TPI.That is some jump in performance. I can only pull low 14s with my stock L98. Tire spin is my biggest enemy. I know a few LT1 owers who can't get below 14 seconds either.
anybody try this intake yet?.....
Yes , I fitted one to my 82 collectors and the engine wouldn't run above 2000rpm. A rolling road session revealed that the fuel mixture was becoming progressively weaker as rpm increased. In fact, there was so much more air than fuel thanks to the better porting of the Renegade. To my knowledge there is no way to increase fuel flow from the Rochester TBIs without grief somewhere else. I refitted the original manifold back on and all is now good. I had previously fitted a Performer cam and Aluminium heads. The car is very sharp now especially low down and I will not look for any more power for the time being at least.
The renegade is not that well made, the plenum top is retained by countersunk screws which do not seal well, there is a cut out for the oil pressure sender unit brass fitting at the rear of the engine but on my manifold the cut out out was too small and I had to rework it in order to get the assembly to fit the block. The take offs for the heater connections are wrong and adaptors have to be used or specially made If there were to be a way to make the manifold work it work then it would be probably be worth doing I think. It is stored away for the time being but if anyone is interested in it let me know.
Lastly, does anyone know how the auxiliary cooling fan on this model gets it's engine temperature signal as I can find no additional sensor anywhere for it ? Thanks.
So, again, if you have a stock or mildly modifed 82 or 84 Crossfire motor, my advice is to take what you may "hear" about the Renegade with a grain of salt until someone posts some unbiased, comprehensive test data.

Like any part, it might need some massaging here and there.
I have a Renegade and it's been a great intake aside form a few small details here and there.
Here are some of my thoughts...
- Plenum Lid: I purchased a huge sheet of gasket material and I made my own gasket for the plenum lid. I wasn't keen on using a bead of RTV.
- Oil pressure sending unit: I have a 45* fitting on mine and I shaped the brass with a Dremel to fit it.
- The temp sending unit for the dash is in the head if I recall.
Thanks for the above comments. making a gasket is the best way to go I think but did yours run OK afterwards ? Regarding the fan sensor, the only ones I have are for the Anti-Knock which is below the RH exhaust manifold, the oil temp sensor on the rear of the block near the oil filter and the water temp sensor for the gauge on the LH Clhead below the exhaust manifold. Not forgetting the temp sensor for the ECU which in my case is in a modified thermostat housing as my aluminium heads don't have a large enough tapped hole to accept the sensor. This leads me to think that the overtime signal is somehow generated in the ECU. The plot thickens as they say!!!
Hope that helps!!!

Here is a schematic of the pins used on the 84 ECM harness. I don't see a pin for the fan.
The knock sensor should be in the block... above the oil pan... on the passenger side in a water jacket fitting. I am assuming that's what you mean by below the exhaust manifold.
