I dynoed my car this weekend. What do you guys think of my results? Too low?
The motor is a GSR with oversized ITR pistons, Skunk2 Intake Mani, AEM Intake.
Stock GSR Cams, Stock Si Header.
Max of ~160 hp at around 7900 rpms.
I expected to lose power around 8K, which I did. I am hoping to gain a lot more power past that point with some CTR cams and a header.
Other than that, the curve itself looks very good in my opinion.

You'll definately need cams and a good header to take advantage of the manifold.

 

which shop did u go? and how much they intall the pistons for u?

 

Good start.. Clean graph, very smooth I like that. Cams would be a big improvement..I wanna see more!!!

 

ha, thanks... I wanna see more too!

Pattersons Automotive put the pistons in..... I think it was aroud 400 to bore, hone, assemble, etc (including all new bearings)

Do you think you will upgrade your valvetrain besides cams, because a Toda valvetrain setup would be very nice. That's what my plans are. Also some porting and polishing in the head.

 

Time for a better header and some High Lift Cams

 

That seems good to me. Isn't that about what a stock R puts down? Did you rebuild the engine?

 

you should be very happy considering you have no header or exhaust, i'd expect a setup like yours to put down more like 150 tops, so for a stong motor

 

get a header and some new valvetrain then youll probably be able to make power up to 8000 rpms or higher but youll also gain more power!!

 

Thanks everyone. I looked around and it seems that most stock ITR's put out 165 max to the wheels. So I am confident that some CTR cams or higher lift cams will help out a lot.
I am trying to decide what all on my valvetrain I need to upgrade.
I was thinking I was gonna go ahead and upgrade my valves since I need to replace my valve seals sometime soon. So it makes sense to me to replace the valves while the head is off.
Any ideas on valvetrain upgrades?

 

Good power, very nice and smooth.
