Went to dyno my car for the first time today. I am pretty happy with the power I made, since I went pretty cheap style on the n/a mods. Anyone know what a stock GSR will put down to the wheels on a dyno?





If you can't read it, my max power was 153, and max torque was 116.9. Mods are:
Iceman CAI
Kamikaze 4-1 header
Powercore 2.5" highflow cat
Apexi N1 exhaust

Not bad at all

 

nice. how do you like the N1? i just bought one off a homie for 2 biLLs and have yet to instaLL it.

 

Are you planning on going sc? Most NA people don't buy the kami header. I made 157 with the mods listed in my sig minus the flywheel. I need a cat.

 

i put down 151.8 with AEM CAI, GReddy SP exhuast and a VAFC

 

Nope, I bought the Kami header cause it was super cheap, hehe. I have all my turbo stuff sitting here behind me just waiting to go in. I bought mostly cheap n/a parts cause I knew I'd be turbo'ing it in the future.

I like the N1, sounds great to me. I don't like that the muffler section doesn't fit exactly right, it melted a small hole in my bumper :/

I think with a better header my car would have made a few more hp, but I'm happy with what I got for sure.

154.8 peak HP/114.9 peak TQ with DC 4-2-1 and DIY icebox
155.9 peak HP/116.3 peak TQ with DC 4-2-1 only

but we all know peak numbers don't tell the whole story, right?

 

you lost power with the DIY icebox ?

 

Wow, nice

 

like i said, peak numbers don't tell the whole story. below 4400 RPM my torque increased by 10 ft-lbs with the icebox. and all the way up the rest of the powerband it was down by 1 hp across the whole board, but that may have been the fan blowing directly on the exposed air filter when i removed the icebox/airbox cover. so for $10, it's a pretty worthwhile mod

 

I hear you, peak isen't always everything, when I went to the dyno and tuned in more and more fuel down low at like 3000-4000rpms I kepyt getting more and more torque. That mid-low end torque gained was definatly noticeable driving around!

 

a/f ratio?

 

Dunno if your asking me, but mine was around 14.?? below 4500rpms and 12.0 to 12.3 the rest of the way..... but thats turbo tuning, n/a you want different a/f ratios much leaner then mine.
