Geoff's pulls are the Blue ones, mine are in Red.
The big differences between Geoff's and my car is mine is a 2.2L and his is a 2.0L... and I have s3 cams and MIVEC... I believe Geoff has s2's?

If you look in the "break in EFR7670" dyno thread I made I overlay the Red with teh 7670.

I think this is waaaay better. And I haven't turned it up to 40psi like I did with the Red just 25psi on the EFR

What boost are you planning to run the EFR on when its all settled in? How is the transient response?

R/TErnie

iTrader: (32)

Transient is awesome better than the stock 9 Better than my BB HKS7460... better than both of those by a good margin. And makes a ton more power.

Planning on running 40psi peak....and as much as I can past 5500RPM.

Very interested to see how that goes - when will that happen?

R/TErnie

iTrader: (32)

^ Eh.... planning that hopefully for next week? Like to get it done during the week so i can run the car on the Friday night drags at Mission...with some trick fuel.

MrLith

Awesome - good luck, and keen to hear how it goes

Wow tq at 3500 vs Geoffs is nuts. Both set ups are still awesome none the less.

Sick.

So are these turbos readily available now??

Very very helpful, thanks for posting this. These are the exact 2 turbos I would love to see tested back to back.

Nice numbers. I am definitely going with one of these turbos. Can't wait to see your high boost numbers.

are you using the top mount internal wastegate manifold like geoff?

R/TErnie

iTrader: (32)

Mine is a top mount that I made for myself. Twin external MVS gates.

Geoff's has shorter runners (better)
Merge collector (same as mine...but a little shorter length/higher angle)
and he uses smaller diameter runners.

So Geoff's manifold will have better boost threshold than mine.

as far as commercially available manifolds for these turbos.. I REALLY like Geoff's Full-Race top mount setup he made for his own car for the IWG turbos. great manifold

i was looking into the full-race bottom mount. i wonder how the numbers would compare

Go loot at leetevo's dyno that is the commercially available (bottom mount) full-race set up on a 2.3 (EWG 7670 1.05)
