This is on a Dyno Dynamics "Heartbreaker" dyno with boost limited to 25lbs ( Winter Tune/Stock Block) This turbo has sooo much more in it! Can't wait to see where the top end is with it...

The motor will be built out to handle max tunes and boost on the GTX3071 in March along with the SST Tranny.

SSP's 600HP upgrade + DCT seals along with the new LTW flywheel

My 2011 MR is having fuel pressure problems that are probably due to the Surge Tank install.

We will be re-routing the return line back into the regular tank to see if that corrects the inconsistent AFR graphs...

Goals: 390-400WHP @ 28-29 lbs of boost on 93 Pump after the block & SST builds...

~430-450 WHP on 106 Octane and 35-36 lbs of boost

 

nice numbers& power!!

 

subscribed for update... fellow GTX'r

 

nice to finally see some results.
Also a fellow GTx user.

 

why so laggy? the whole point of using this turbo is for spool. may as well have gone bigger with that ****ty lag;.

 

Good luck running 35psi with the SST gearbox. I've got a pretty big build and I need to rescale to get my load below 300. SST's don't like anything over 300. . .

 

LMAO....... you serious my dude? Your trying to say that this 30R Turbo should spool like the Stock X Turbo.....

I'm pretty sure that spool is on point.... It has a nice boost curve and makes power where it should be... Keep in mind this is a MR also so on a GSR there would be a bit more lag.

If you have another graph of a 30R EvoX that spools much more sooner please by all means post it..... But if there's any signs of "Brake Boosting" (Yes I've seen it done on paper and on YT vids) on the dyno or creating lots of load to get the turbo to spool before the official dyno run, your post will be invalid.

 

My 2011 MR now with a Stage 1 build and Kelford B's on 109 Octane,


Peak boost 30lbs


93 Octane MAPS soon...

The Shootout graph is lower than flywheel but higher than a dyno jet.

+11% is a solid convrsion factor to figure Dynojet #'s vs Dyno Dynamics

Dynojet approx on race gas: 445HP/422TQ

Figure the Kelford B's are about 30HP of these #'s

Dyno numbers on 93 pump on he Dyno Dynamics ere : 368/320 Dynojet would be 405/355. Those are solid #'s for a stock frame BB turbo on a MR

The car shifts fine in every gear in Spt and SS...Mission accomplished.

I have added the 93 Octane graph so you can see the 4 PSI boost difference between race gas and pump 93...

 

375 torque on stock SST?

 

Yes that is correct. Its a dyno Dynamics Dyno which reads 10-12% lower than a Dyno Jet. SO peak torque and HP are actually higher that that!


The case has never been cracked on the car. No clutch packs etc...


65K on the tranny and the Stage 1 engine has allowed me to run the **** out of the Garrett GTX3071r with a 0.73 AR

 

Sweet. Cant wait for the upgrades to see more results

 

Awesome torque. I'm running the GTX3071 0.94 a/r on my 11' MR. Interesting to see the difference in spool vs top end between the two a/r's.

 

That is the easiest solution but there are other things you can do in the trans tune to keep it happy.

 

wow very nice.

 

from what i have seen the .94 just adds lag. but that is just a subjective comment from seeing the .73 graphs which look just as powerful as any 94 results posted. people have just assumed the 94 is a better idea. no one one has done a back to back on same car to actually compare.


there were really nice gains here going from 25psi to 30psi. the 73 housing is flowing nice and not holding it back at all.
