Viper,

JD is right, but I'm not sure the difference in trim amounts to any measurable real world difference to you. One is a 56 trim and one is a 52 trim. At 20psi, the difference in efficiency between them is 1%. The trim has no effect on the ratio of the major diameters of the comp. and turbine. Because of the more ideal wheel ratio of the gt4294r compared to the gt4094r, it will spool just as fast as the gt4094r, and you'll have less backpressure and run cooler and make more power with less boost.

 

My car is currently at PFSupercars right now, and I'm shooting for around 530hp on pump and Ray said it's very possible with my mods with water/meth. Hell, I might even get more, I'll let you know once I get it back and break in the motor and go back for the final pump tune/race gas tune.

EDIT: And it's going to be my daily driver, except I'll only be running 15-16psi since I have a 15lb wastegate spring daily, and raise it up when I want too.

 

It's a guess on my part about the fuel blends. I don't know honestly if they've changed but I've suspected that they'd get ever-so-steadily worse over time due to the EPA guys putting possibly stricter and stricter restrictions on things. Maybe it's just my pessimism doing my thinking for me.

Now that is funny, tell your friend thanks for the amusement. Talk to Ray at PFS he is right by you and can more than show you what want.



I agree one hundred percent! I think you'll be better off running a 4294R on either a nice TiAL housing or the T6 I haven't been too big on the T4 frame on the 42R's 4094's are nice for packaging but that's the only benefit over a straight 42R.

 

Copied from the NRS thread, will likely post in the AI section as well:

Here is some VBOX data on Jake's Capella taken from Ausrotary including Pete's comments and a link to the thread. This car made 3 runs in the finals at summernats making 563 RWHP, 582 RWHP and 588 RWHP respectively. This was done on a Dyno Dynamics so for Dynojet the figures would be approx 647 RWHP, 670 RWHP and 676 RWHP respectively. Done on NRS 3mm 1pc

DEFINITELY READ THIS THREAD FOR THE FULL STORY ON THIS CAR Pgs 5 - 6
Also a pile of info, links etc for the Racelogic VBOX. Any questions you have for Pete you can ask them here:

Boost is higher also, but cant give all detail but there is enough here to keep you interested, you will see true vehicle speed, rear wheel speed, rear wheel slip percentage and some other interesting stuff :laugh:

**note waving rpm line is due to wheel spin/slip** and struggling for traction, but still enough to out accelerate a Pagani Zonda

OR every single body panel will fly off, and the street tires will explode :!: (more like it LOL)

yea, my dyno representative was telling me about a bad *** rotary at the summernats this year! then rice hit me up with the good news fo sho!!!! great stuff
