WOW! i make slightly les hp at a lot more boost. that is a freak for sure. nice job

How much do you attribute to the FP4R cams? The intercooler?

I'm thinking Cams, Intercooler, FP and Injectors and I should come see you again

Hmmm....I kinda wonder if the boost reading is off. 400 on 93 and lower than stock boost. Hmmm. That intercooler isn't doing much in the cooler temps. The stock flows good. Hard to believe cams, that intercooler, and tuning are getting 150 hp over stock on only 18 psi.

Thats a head scratcher for sure. I'd be curious to know what made all that power.

cams, fmic and piping are doing wonders for it.

the stock fmic flows like garbage, look at the size of the runners compared to the buschur race.

Kevin kept the stock fmic and went from 320-350's with GSC S2's, it's choking badly. He just swaped it out for my spare buschur race fmic, I expect he's going to jump into the 375+ area easily with a retune when we get time.

So the torque isn't that impressive but I was surprised to see that it still managed to make over 400awp on 93 octane. He's going to picked up a walbro and 1000cc injectors and come back for a re-tune, I suspect we might make more hp and we'll definitely make more torque.

Hmmm
I made 355 WHP (DJ) , had 110-115% IDC @ 11.5 AFR on 93 stock fuel pump , I just dont see there being 45 whp more fuel left in it

comparing dyno numbers isn't always useful and I've noticed a significant difference between some cars and how far they can go on the stock pump/injectors and others. As a rule of thumb the pump should be replaced right away so it's a non issue.

+1

it made a big diff in my tune , fuel map was in the higher 8's and now high 9's/lower 10's and IDC are down to 100-105% , afr 11.2 vs 11.5

sounds like you added a ton of fuel in the map to compensate for the weaknut pump. I turned down the boost instead and I suspect we're not going to see the same thing with his tune when he installs the pump/injectors. right now it's my normal fuel map for those mods + 5 fuel to bring the AFR down to where I want it. So it'll go a little richer but nothing too crazy. I'm not saying what you did is wrong, just a different approach to the issue

Replace "wrong" with "safe"

kmcconn9 · Oct 20, 2009, 08:08 AM

wow, impressive!!

project_skyline · Oct 20, 2009, 09:39 AM

I suspect the car has a really strong motor as well. I'd be interested to see compression numbers.

charon2123 · Oct 20, 2009, 09:49 AM

Wow, great numbers! Chris is an awesome tuner and a great guy. My car is at the same point where the stock fuel injectors are keeping it back.

sprx19 · Oct 20, 2009, 01:47 PM

Well regardless, awsome numbers.

TakaseEVOIXSE · Oct 20, 2009, 01:49 PM

wow... im assuming the only relevant mod is the addition of the Fp4R cams? Interesting... i think i may have my new cam choice, lol!
