I didn't see this covered before but might have missed it. If so ignore this and direct me to the thread.
I think this would aide people in deciding on the NA or FI route:

Please post your highest WHP with all current NA mods. Please be specific and an estimate of total cost would be nice. Thanks everyone.

 

direct yourself to the dam n search button! JK!!

 

I think its some guy named Adam from Z1 Performance...

 

I made 261whp dynojet with basic bolt ons, non rev up

 

Jeremy was a bit higher than me since his compression was through the roof and on race gas. On pump gas, that's showed a sheet, I think my car and then Ritchie from Australia would be the 2 top, along with another gentleman in the UK - we're all right around the same figure

 

what figure is that may i ask?

 

i think , japan has got all the NA tuners here beat with reguards to NA hp...i remember seeing a article on a white Z that was pushing 345 rwhp not bhp with a diff ecu and every mod possible. NA wise.

I think we need to learn more on how companies like mines and amuze make good power NA and also other companies like the attkd Z which was the highest NA Z i ever seen and it reved like a bat out of hell. Japan def has the tuning scene on NA locked. I just dont get why we dont have the same privieldges..is it money or just they arnt letting the good knowldge out man. Im tired of seeing Zs on best motoring reving to hell with some amazing NA hp levels and where still trying to break the 300rwhp goal on a daily baises . LMAO just venting.
damn u japan

i think if we can come out with some affordable means of making good NA hp with tuning , alot of people would stray from FI. Alot fo vids and tuning shops from what i scene get more props in japan for the NA setups thent her boosted since boosted is so common. Or more props on there engine response from cars....damn they have it like a art. Hopfully we get some goodness aswell. With people like Z1 i beleive with the 303+ and Jermey with his high comp ( though not daily driver) we can unlock some things to get beyond this 300 mark man more commonly.

 

Here's mine N/A definately not the highest. Dyno Dynamics...about 281whp on Dynojet

 

Im in the process of install a NA motor built by Forged Performance with Cosworth heads with 272 intake and exhaust cams. Hopefully I will be breaking 300 rwhp as well. Hopefully should know in a couple of weeks.

 

Do it!!!! Gonna be hard on the "heart breaker" (dyno dynamics)

 

I made 267whp on a dyno dynamics...not sure what it would be on a dyno jet....

 

Hell yeah it will be hard....its going be down to the final compression and intake system...if the cosworth intake proves its worth may need that to bust 300.

Made 264 on a dynojet with Nismo headers and exhaust, gutted cats, JUN lightweight flywheel, MD 5/16 spacer, and stock intake with a K&N filter.

 

'bout 293whp that's damn good

 

is the cosworth intake plenum really only $300?

 

woops read it wrong sorry

 

mods are

JWT S1 cams & springs
Topspeed headers
Strup Test Pipes
Borla True Dual
Injen Intake
Motordyne 5/16"
Greddy emanage blue (ewww)

Put down 236 on dyno dynamics, I think it would be around 280 on a dynojet. I also want to switch to UTEC and get lightweight pulleys.

Ultimate mods would be to upgrade the heads and do individual throttle bodies we'll see when that happens tho lol

 

Lightweight pulleys feel great...absolutely worth doing! I can wait to see what a lightened flywheel feels like. Rev matching is crazy easy now!

 

236 on Dyno Dynamics=about 259whp on Dynojet give or take a few depending on ambient temp.

 

im at 267 rwhp stock we'll see where i get

 

hmm should be higher since I dynoed on a dynojet (I believe) prior to getting cams and test pipes and I came in at 259.8 whp.
