Question 950whp+ Turbo Suggestions

Hey guys I've been looking online for pte6870 results on evo 8/9 but so far only found one dyno result on evom.
I'm doing a 2.2L motor with a rpm limit of 9500 with all the supporting mods imaginable.
I'm just trying to decide on which turbo to get to achieve my goal of 950+whp. I've got my eyes on the Precision 6870 but my tuner says it won't reach my goal hp. He's suggesting the Garrett GTX4202R but I'm concerned about the spool etc. Any advice on which turbo would suit my needs?

Here's the spec list:
Nitto 4g63 2.2L stroker w/ billet crank, I beam rods 625 rod bolts
CNC ported evo 8 head
Kelford 288 cams
AEM cam gears
Kiggly valvetrain
+1mm supertech valves
ARP 625 head studs
Racefab extended sump
Buschur 1000hp rated CDI COP kit
Bosch 2200cc injectors
2 walbro 450lph intank pumps
-10 fuel feed and -8 return
JMF drag or race intake manifold w/ S90 TB
Sheepey 1000hp intercooler w/ 3 inch piping
JDL auto T4 Twin scroll FF turbo kit
2x MVR 44mm wastegates
Either Precision HP cover 6870 1.00ar OR GTX4202R 1.01ar
3.5 inch exhaust from turbo


Here's some pictures of the Evo all the way from New Zealand

The 6870 will do 900ish whp on the same dyno on your setup on E85, at around 45psi.

how long has it been on 700whp?

is it reliable on that whp range or requires constant attention?

consider a super 99 or 6870

we made 930 whp at 46 psi on a 102 degree day with the 99 but a 6870 will do the same....on T3 on stock intake manifold ported....you should make more.


if you want fun and quick spooling a 6466 wil get you there also but with a lot more hard work

Seems to be doing ok for now. It has been on 600+ for 3 years and 700+ for around a year now and holding strong

To be honest I'd love to use the 7275 but there's no divided twin scroll option for them as far as I know

S369 with 71 upgrade 115 lbs per min should do the job

Would there be a considerable spool difference between the super 99 and the 6870?

On a high reading dyno, such as are most dynojets, you might be able to do 1000+whp on e85 in the range of 45 psi on a 6870, but if you want a true 1000whp, you will need a 70mm+ inducer turbo with 80mm+ inducer exhaust wheel. How much bigger than 70mm inducer, it will depend on the compressor wheel aero and blade surface, not all 64mm, 68mm, 69mm or 71mm inducer i.e compressors flow the same nor do they have the same mechanical boost threshold and transient response on the same setup. On a low reading dyno , I'll use the Mustang one as a common point of reference, the pte 6870 or a same size BW, will not do 950whp but it can do 850-880 max whp. On the dyno you are using it will do, estimation based on the s362 one, 900-910 max whp on pump e85 fuel.


A dyno is a tuning tool, so find one which it is the most strict in reading/converting torque/inertia to hp as what really matters is the lap or drag times and e.t. I would much rather built a car that has the lowest dyno numbers from other cars in its setup range but beat all them on track, than the opposite.


Consult your tuner, if he is a properly knowledgeable individual in the field of tuning he'll suggest the right turbo among those that exist on the market or have a custom turbo made, tailored better/more to your needs. Making the best setup for a certain purpose goes beyond choosing a turbo or certain parts and bolting them together, or following a recipe that you find on forums such as this one.

Is this Extremetuners? btw BW EFR series but wont make as much power as PTEs or FP with similiar size wheels.

What do you mean by high reading dynojets they are pretty much the standard. Mustang Dyno can be manipulated like virtual dynos. Guys like Buschur, TPG, CBRD and ect are honest and will give you lower reading results. On a MD Dyno if you want to manipulate it you can however.

On Dynojets its either uncorrected or corrected with soothing factor.
