hey whats up guys i have a quick question if you take off that black plastic engine cover does the motor stay cooler, my current set up its a jwt popcharger-ztube combo with topspeed res test pipes and greddy evo2 exhaust

 

I would think that removing the OEM engine cover would allow more air circulation over and around the plenum. Adding the MD 5/16" spacer ISO copper will also allow your engine to run cooler plus improve response. Our engines LOVE cool mornings....

The spacer and iso thermal won't do too much for you as far as cooling goes... it's the aramid gasket that keeps the temp of the plenum cooler. The whole point is to keep intake temps low, and it won't make sense to keep the upper plenum cool while the lower plenum is still heat soaked because the heat from the lower plenum will still affect the air temp inside. The iso thermal is for the throttle body, so that's a different aspect that Motordyne's full kit also takes care of.

 

ok now with the plenum spacer i live i ny and i actully wanan gain some more lowen becuase i lost it with the testpipes and exhaust so which would be betetr the 5/16 or 1/2 spacer? and i hear alot of guys have oil leaks i dont want that i wana keep the car n/a for now till i pick up a spare motor. thanks for your help i noticed a big diffrence with the jwt with the ztube as far as temps plus i run q jp synthetic oil which helps to, thanks for your help guys

 

i was reading that the biggest gains are from the first 5/16s and negligible once u hit 1/2in so ur better off saving ur money and getting the 5/16

 

"IsoThermal" are the two items - coolant control valve (or copper plate) and the Aramid gasket... its a kit. The goal of both pieces is help allow for cooler/denser air entering the combustion chamber.

There’s no reason to stop there either… ceramic coating (or other thermal coating) of the lower collector is a good idea too… personally, I’m very anxious for the MREV3 (phenolic lower collector) a better choice than all the aforementioned.

 

ok so 5/16 it is anything else to make my n/a ride faster ima be getting cob tunin swaybar kit iwth the lowering springs, md 5/16 spacer adding sum lucas oil treatment to my oil rlyy helps keep temps down as well and i use the lucas oil injecter cleaner rly works great lubercated the pistons as well as give better gas mileage

 

Wait, what??? Links?
