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.
Yes the Renegade lid is retained by SS countersunk screws and IMO it seals up fine, always has negative pressure. The only time the seal could be stressed would be during a backfire.
I also had to make some minor adjustments at the sending unit as u mentioned but never had issues with heater connections. My biggest issue was to machine off the rocker covers from front to rear on an angle to make fit. And on the angle because I had to save the gasket sealing surface.
I couldn't find the temperature sensor for the auxiliary cooling fan either and its not in my AIM. It's right to the rear of the dipstick and above the exhaust manifold, brass with 2 wires. The other end connector is in with the A/C pump connector.
