Yes, we make all 128 harnesses long enough to place the computer under the passenger seat.

LOL I can't believe Larry left the amp disconnected. At least you had the sound of the dump tubes and turbos spooling to keep you occupied

Took this from Supraforums.com (but its a GTR build).

This would be basically the extreme limit of what the 20G's can do I'd say (since the GTR heads flow better anyway than ours)

So that's what a set of real 20G's (non-hybrid) can do. Nice. And with Tubular manifolds.
I wonder who made those? Custom? any idea?

Looks like that shop built them.

But I'd say this would be the ideal situation for 20G's when comparing them to our motors (this would be a fully ported head, bigger valves, big cams, tubular manifolds, etc).

SPE's GT-R put down 866awhp/849awtq with the TD06SH20Gs.

2 Bar, C16.

9.6@150mph w/ Drag Radials

However, I am not sure if they are using the standard hot side (IIRC 8cm^2) or one of the larger options GReddy offers.

Different power band. You make peak torque sooner then I do which should be the case since the 18g's will spool quicker. Also depends on your cams, manifold, etc......

Holy crap nice - how much boost was that? Tell me that was done in the winter in ATL! If it was during hot weather, you can easily add 15% to compare to Dynojet STD. In cold weather with no correction on Sharif's DD dyno, the readings are more comparable depending on how cold...

BTW, are those the real 20G's or Hybrid like mine (upgraded by Forced Performance). Also do you use the upgraded inter-cooler and associated cold side piping? Thanks.

they are upgraded 20g's. I know the hotside is choking my motor and I am looking at getting something bigger from greddy or see what else FP can offer that will work.

All my piping is the same except the one that goes from the IC to the TB. I did redue that one with less bends and it is now a full 3" all the way. Other then that all my piping is ceramic coated on the outside with a teflon layer on the inside as well as the intake manifold and lower intake runners.

GReddy R35 TD06SH-20 Twin Turbo Upgrade Kit. Well we are happy to report an update. Over the weekend, they began to boost up a little more from their 706whp @ 1.45kg/cm2 to a crazy 816whp @ 1.7kg/cm2!

Not only does it make great peak power, but if you notice on the graph, the mid range is still quite good with 360whp at 3500 RPM & 520whp @ 4000 RPM...

And the guys at SP Eng, tell us they are not done yet. We can't wait to see how much they end up with!

Interesting to see where the 20G's run out of breath...

meatbag, where is your battery and what is in its place in that compartment?

Nice piping and catch can setup!

(I don't see check valve preventing boost from going backwards through the catch can - just use stock PCV I presume? So you're catch can sees 18 psi etc?)
