The spool is average for a 2.4 on a stock appearing setup. I was talking about the air fuel curve and how it looked more like a ekg than an air fuel curve. Usually in my logs I get that same type of behavior when brake boosting.

You cant compare these to the twinscroll old school FP stock appearing turbos.

This cars a Stainless single scroll housing, stock final drive + evo 8 gears, and produced over 800whp and still seen almost 40psi by 4000RPM in 4th.

If we brake boosted this car, it would compressor surge and most likely not even get out of the spool to complete the pull at the RPM we started the pulls.

The AFR isn't doing that with the car, its just how evoscan and the laptop is picking it up.

Keep in mind my numbers were in 85-90 degree weather. He also has a larger TB mine is a 65mm vs his 75mm idk how much that matters at a 700whp+ level. He has i believe has a more ported IM also. Mine is just a Rev 3 intake manifold, His seems to have so extreme porting also don't know how much that really helps either.

100% agree, i took my car out last weekend in 65 degree weather. 37.6 psi was 756whp i believe @8k can rev to 8.5k just don't like to doing a pull not racing no point. If i ran 44 PSI in 50-60 degree weather i bet if i had the fuel it would be over 840-850hp in 3rd.

I see, what wideband is this car using?

Now this got me thinking about a zephyr instead of a black setup on my car.

Its not the wideband doing it, its just something interfering with its signal. I think he runs the Innovate LC1. Unless the 3 port is maybe trying to kick the WG open on spool, but that would show up as surge when running the car, and customer said it pulls super smooth and very clean. I have had them flutter on cars before as they were spooling up, but once tweaking the WGDC that goes away.

Ya Zephyr seems like a nice option also.

Steve those parts make a huge difference. The bigger throttle body helps a lot once you get to flowing as much air as our cars are. Your car is where it should be with its parts. Plus you have a very healthy trap speed which is what matters the most.

Great job Tom. Solid numbers.

FP turbos always put down great numbers. Thats why we recommend them over all the other stock frame options.

You and me both buddy.

Thanks guys, the car feels like a beast. It spins from a second gear roll and a 3rd gear roll on 255/40/17 nitto nt05 lol. Tom has spent plenty of time messing with my car and i think the results are amazing.

For anyone who is worried of the "lag" of the black compared to this, don't be. the slight lag difference is barely barely noticeable, but the top end power is crazy.

No brake boosting at all in fourth gear or third.

Currently running an aem uego wideband. I previously had an LC1.

the powerband does look amazing. the spool is exceptional for the size turbo. looks like a home run for an fp product

Great info!! FP ftw!!

Good work Tom. Definately my next turbo. My low mileage DBB FP Black will go on sale soon lol.

We'll have our O2 solution available very soon!

That's what I was waiting/looking for. Thanks.

How are these center cartridges holding up?

Very nice
