im not saying u didnt make those numbers but i highly doubt it was on 10 lbs especially with droped compression with there kit out of the box

I'm not doubting the numbers I was just wondering about this.

Gimme a break and let me do the math.

A stock engine is 11:1 and would do around 320whp with a GT3070R running 8psi (that's already on the high side, looking at the dynos being posted) For another 2psi, you would see a maximum of 360whp, based on 20whp/psi what is already a mirracle.
Based on that,your set up would have to make another 40whp more IF the compression would be stock.If....and that would be on a VERY HIGH side.
It would take more than additional 2psi of boost to compensate for the drop in compression, just to make the same power.

So how the hell can you do 40whp MORE power with 10psi and a 3mm headgasket than a proper turbo kit would do on stock compression with 10psi?

I am the first to call and putting on my flame suit.

(to be honest I was exited till I got to know about the 3mm detail of the story)

Reminds me of the stock Spoon engine dynoed at 240whp

Power is made in timing. Timing blows motors. Timing can save motors. Power is made with proper timing vs. reliability, take your pick.
Sure, I can crank out 30hp/psi, but how long will the engine last? How many versatile conditions can I run my car at, and not worry about things?
Not saying it didnt happen(not saying this AT ALL!), just explaining that timing=power, and A/F ratio comes second.
BTW, all of my basemaps are fairly shallow on timing, for reliability purposes

well let me clear some things up since I tuned it. If you look at my first statement I mentioned the car was uncanny. There was no boost controller or boost guage on the car. The owner had placed a 10 psi spring, so he was using the wastegate to control the boost.

Cody is right the AF does come second and timing is critical, thus why I let the stock computer control timing for most of the map, then transition to inputted setting. Forutnately, emanage allows this when a value is not inputted. My primary concern is the longevity of the motor. I did not tune this car so he could drive it for 500 miles then kaboom.

I guess the only way to find out is to get a boost guage in there and find out exactly how many pounds of boost this car is making. The owner is not going for any records he just wants a fun/safe ride.

The inline pro manifold seems to control boost pretty well, so he cant be any higher than 12psi(which would make more sense).
And I need to grow some nuts and mess with my timing, learn the "fine edge" a little better Im practicing on my 10:1 all motor setup before I boost it, that way if things get ragged, the chance of blowing the motor are far less than coupled with 12psi of boost.
Good tune job nontheless Arnold!

This number may be possible with an equal length manifold on 10 psi and a 2mm headgasket and a very unsafe tune. But I can't see it being done with a log style manifold at 10 psi. And especially with a 3mm headgasket.

I made 310 whp on a dynojet at around 6 psi with a fat tune and only running around 15 degrees of timing. If this was tuned in, I'd be closer to around 330 whp. At 8 psi with a sweet tune and more timing I should be around 375 whp.

if full race made 450 on 11psi and john at inline like 500 something on 18, then why can't he make 400 on 10.
