Stock dyno numbers and first mods
I have an 03 touring 6 speed Z and had it dynoed last weekend. It is all stock and dynoed at 226hp to the wheels. While the car was strapped to the dyno, we installed the Motordyne 5/16 spacer kit, minus the lower thermal gasket, and redynoed it. The car made 238hp to the wheels. I was very impressed with the gain. I have since purchased a Stillen pop charger and a carbon fiber cooling plate. I'm will install these items this week and redyno the car this weekend and post the results. I'm also having the stock plastic Z tube replaced with a custom metal tube and having it thermal coated as well as thermal coating my intake manifold. I will dyno after every mod so I will know the gain of each item. If any of you guys have any suggestions on my next mods, I would appreciate them. I know I need an exhaust and any suggestions on that would be a help also.

I like this new member already.
I literally just ordered the 5/16 spacer myself. Nice to see such a decent gain right off the dyno, on the same day. I will be interested what kind of gains your other mods produce.

I installed a Stillen intake today and a carbon fiber cooling plate. I'm also having my metal intake tube made and thermal coated this weekend. I should have my car on the dyno Saturday and I will let you know how much I picked up from the intake.

Well, it's official. Re-dynoed my car today with the addition of the Stillen intake and the temperature was actually a little cooler today than when we last dynoed the car. I lost 3RWHP and 3 FTLBS of torque. Isin't that a kick in the groin? I didn't expect a substantial gain but I really didn't expect to lose HP. So, do I go back to the stock airbox or just say it looks cool and keep it? The test pipes should be here by Monday, I hope I dont lose more HP when I put them on. Any suggestions would be appreciated.

Exhaust Whore
iTrader: (37)
well there is alot of variables when u dyno ur car for comparison against stock. Did u reflash the ecu to relearn ur mods? weather change? What gear? what kind of coating and intake did u have? the CF plate u added is pretty much for looks or highway speed. Why dont u put on exhaust and ur tps then dyno it with the intakes on! Then take ur intake off and put the stock airbox back on and see what u make. Since intake is a breathing mod i could imagine it would be better with other breathing modifications. List can go on
Btw how did u get a stillen intake for a 03?

Just called and spoke with Polk about getting some headers installed. Seems like they are good guys to deal with. I might have to make a trip down there soon.
Thanks for the referral!
