ESS VT2-625 Dyno: Macht Schnell Test Pipes

Here's a before/after dyno of an ESS VT2-625 equipped M3:



With the Macht Schnell Bypass Track pipes fitted, a healthy ~20whp gain can be seen clearly throughout the powerband.



Runs are on 91 octane, the "air raid" siren you hear is from the Toyo 888s on the roller.

Tom,
I've always found the numbers on the ESS-550/585 (not sure which is which) to be very impressive as the other dyno you guys posted with the non intercooled kit was like 520whp/330wtq. Is there really that small of a difference between the kits (625) power wise? Is the main benefit of the 625 that it would obviously have much better track capability with the extra cooling? Just curious as I'm sure some others are as well. From these dynos it would appear that for someone who uses their car only on the street the non-intercooled kit is an awesome value.

Very nice gains from just the test pipes on this particular car!

I completely agree, bang for the buck - the VT1-550 is hard to beat and will satisfy most needs out there.

While the 550s will run on the track, heatsoak will eventually set in on extended sessions. Street driving won't be much of an issue. If the plan is to upgrade in the near future, at least run with the any of the VT2 systems so the manifold will not need to be swapped at a later time.

Ah yeah was unaware of the extra upgrade needed if not going with a VT2 to begin with. Any of my buddies going with an ESS setup ill definitely make them aware of it. Good info bud!

M33 noted he made around 590 whp on his vt2 625 kit. What other upgrades are required to reach those figures

Hey Alex. This is about what I did SAE on 91 octane with the VT2, catless x-pipe and Akra slip-on on 91 octane.

Now once I added a couple gallons of VP 100 pump gas to get a mix of ~ 95 octane, I added another 25 RWHP.

I added another 10 RWHP with an 8,600 RPM tune.

This is also with a 96mm pulley.

I'm putting on a 92mm pulley on Monday and on ~ 95 octane, should dyno close to 600 RWHP.

So another 70 RWHP is easily possible with some octane and a pulley, since the VT2 625 have the injector capacity to handle it. The smaller HP kits do not.

Yeah I know gas is a big factor on these cars, I feel a big difference in power when I put 91oct instead of 94oct! But I thought after seeing the VT1 with test pipes on 91oct dynoing more then 500whp at EAS that the 625 with primary cath delete would've dynoed north of 550whp. Anyway, no matter the numbers, the performance of these kits is undeniable! I just wish I'll dyno 500+whp with my VT1-535 with Turner test pipes on 94oct(and some nice northern temperature ), If not I'll have to update my kit to the VT1-550 level!

BTW I can't wait to ear how your car is gonna do with that new set-up!! I think you're a real pioneer!
