Vishnu/FFTEC: 738WHP with 6466 Twin Scroll (New World Record)

3000GT MR · 07-28-2013, 03:27 AM

When you say upgraded fuel rail. Exactly what does that entail?

And at what point was this required? Has the HPFP been left alone?

Next week we will find out

I just noticed it does look like torque drops off ever so lightly around 4100.

DriftDreamzSS · 07-28-2013, 06:41 PM

Very impressive, love how the power never falls off.

AWil335i · 07-28-2013, 09:52 PM

This looks incredibly promising. Can't wait to see track times.

Longboarder · 07-29-2013, 01:51 PM

Great work as always Shiv/Captain Insano.

Can't wait to see your car in action at the Airstrip Attack 4 on Oct 5th and 6th!

klipseracer · 07-29-2013, 02:00 PM

I think a twin scroll setup will do very well. Something that interests me more than a big twin. But lets allow the competition to improve our options! I was prepared to be disappointed by this kit, but it looks to be a performer. When do you think you'll see 30psi? A wastegate spring away?

pits200 · 07-29-2013, 02:26 PM

That boost curve is looking infinitely better than past single turbo logs pre-twinscroll.

Congrats FFTEC!

AYF80 · 07-29-2013, 02:32 PM

I wonder if the Top Mount will perform any differently

is there anyone that can overlay a boost curve on that dyno similar to this

I don't see any additional runners that would cause different performance. @shiv@vishnu or the ff/tec guys are probably the best ones to ask though.

BabyZ · 08-05-2013, 05:13 PM

I am ready to see this hit the track.

We changed the boost control frequency of the Procede's wastegate control which smoothened things out nicely. The twin scroll also does a very nice job of eliminating cross-talk between cylinders that can interfere with boost control as well. Also seems to be more knock resistant but some of that could come from the much larger 1.0 AR exhaust housing. We may be coming close to some sort of cylinder head restriction as well. I think we may see some pretty crazy gains with ported heads. But I think we are good with the power at this time. Now it's more about supporting it safety and making sure it is put to the ground. The car is actually really nice to drive on the street. At part throttle, you wouldn't even know that it is so powerful. No compressor surge or bucking. FFTEC really did a spectacular job with the hardware. And the electronic control behind everything isn't so bad either.

3000GT MR · 08-05-2013, 07:03 PM

Shiv will this updated boost control freq be available for existing singles? Or is it better DC in the map?

Yes, I will be posting it up soon. But the new freq seems to be more benefit for high boost twins scrolls than the single scroll kits.

To be honest i haven't been most impressed with the boost control side of the set up. But i also haven't had the time to really investigate or make changes a as id like. Not sure if it's the slightly larger turbo from what it was designed around our what.
