While all of you have been thinking about what to get Tony and I for Christmas, we've been diligently working on doing what we do best; pushing boundaries. I'm very excited to give some details on our latest accomplishment. Specifically, 777 whp on Direct Injection only. We didn't just break our previous DI only record, we destroyed it.

Not a lot more need be said other than we got 777 whp (uncorrected; std was 772) out of our shop car with no port injection used. That's right. Direct inject only. We used our off the shelf double barrel shotgun system which is matched with our special VTT/SS hpfp controller. That's it.

At a Glance:

Uncorrected Graphs:
DI only, 777 whp /701 wtq


DI only, all dynos


STD Graphs:
DI only, 772 whp / 697 wtq


DI only, all dynos

Quick History:
To refresh your memory, back in June Tony was able to get 650 whp with our proof of concept prototype hpfp system. That was exciting from a theoretical perspective but many of you were mildly cranky that we didn't have a hard date on turning that proof of concept into a viable product. We heard you.

The Car:
E90 335
Forged Rods and pistons
Stock head
VTT GC Turbos (http://performance.vargasturbo.com/bmw-products/n54/)
VTT silicone Inlets
VTT silicone Charge Pipe
VTT Custom PCV System
VTT Crank Breather
BMS Downpipes
Custom Dual 3" to 4" exhaust
Custom LPFP setup
VTT Double Barrel Shotgun
VTT/SS HPFP Controller
Custom tuning by none other than V8BAIT (Justin)
NGK 5992 Plugs
M3 rear end swap with 3.15 FD
DSS Custom Carbon Driveshaft
Stock 6MT
PTF Twin Disk Clutch
100% E85
NO PORT INJECTION

More Details:
This is possible with our off the shelf VTT Shotgun Double Barrel, our controller and some flash tuning changes. It shouldn't be a surprise to you that at this level the system is VERY sensitive to fuel system health and capacity. Every aspect of the fuel system must be in absolutely tip top shape to even come close to this DI only.

More questions? Ask away. We're here. If we aren't, it's because we're testing.

I love it, keep pushing the limits.

I'm happy I held off buying port injection.

Promising. Nice work

Link to hpfp controller and "db shotgun" please.

You da man, thanks for doing this. There will always be many doubters aka HATERS but you just keep doing you no matter what and stay encouraged.

Nice work. Now that it's proven that DI alone can get you there, we are open to the evolution of HPFP development.

This +1!!!

This is what a vendor thread should look like. Not that other train wreck.

Can you elaborate on the custom LPFP setup? My stage 2 LPFP will not support my stock HPFP and Hexon RR600s.

How is the second hpfp controlled?

[jpsimon]

awesome

The split second controller. Very similar to how PI systems use it but with the hpfp instead.

Tony made a post on it going over great detail... but it's on different forums.

If you do a google search for VTT 1200+ radium you can see pics. It's a custom system and has considerable headroom.
