22psi

 

not bad on the DD .

did u try going like 25 to 26 psi ???

 

tried it and ran out of injector, 22 psi is good for now

i made a good impression on some Cobras

So here is your 'race gas' E85 dyno overlayed with Cass0007's APS extreme on pump

3071 in a smaller housing vs a 3082


And your dyno compared to a race gas single 67mm turbo on a 6cyl IS300 from this thread http://www.supraforums.com/forum/sho....php?t=542083) (which would easily fit our cars if someone made a t4 flanged single kit!!!! )


and just for fun, my Vortech vs those sweet 3082 turbos

 

Very nice man . Handing out beatdowns to Mustangs FTW!!

 

damn when you put it in a graph like that it makes me totally sad

 

ooouch

 

allso that guy with the blue Z from VTR made 800 to the wheels with a smaller turbo and 23-24 psi what to say

that motor was using a stock heads and cams and made 800whp on a dynojet

 

ya thats why we think you have a TON left in those turbos/ your tune or something....

I just wanna know how we can get this outta a single 67mm

do u mean that a big flang can help to flow more with less backpressure ???

 

I believe that is 93oct + meth, so its very similar to running E85. Also, its not a true Extreme kit, just the tuner kit upgraded to Garrett BB 3071's.

Just for the record, so do I

The log manifolds will be the bottleneck. Doesn't anyone listen to Terry

 

i guess the real test is to see what XKR's car does

 

XKR still have a car ???!!!

 

OP, what supporting mods do you have? What cams? Downpipes? Which exhaust?

If you have it in another thread, you can just provide the link.

 

The downpipes are standard with the GTM kit, I have the first generation GTM Stage 1 turbo cam, ported and polished heads, +1mm valves, Greddy Evo TT exhaust

Maybe the cams are killing my car since they aren't very aggressive for the heads I have

 

Congrats on the new setup. But it's a far cry from your proclamation and previously stated power goal.

Your turbos are not even waking up until 5000 rpm, but then you are only running them to around 7200 rpm. That is a very narrow power band. If you are having problems with your cam phasing, and they are not advancing in the mid-rpms, that may be steeling some of your mid-rpm torque. Before you do anything, the electrical issues need to be resolved.

Nonetheless, I don't think your cams and turbos are well matched. The stage 1 cams have only a 256 degree intake and 264 degree exhaust. Your hp is already starting to fall off after about 6400 rpm, which is not long after the turbos have spooled up. In a nut shell, your cams are not allowing the turbos to open up and run.

To get the most out of those turbos, you need to run up to 8k or 8.5k rpm. So longer duration cams are definitly worth considering. They should help widen your power band in the upper rpm range. I would recommend at least GTM stage 2 cams or BC stage 3 cams (both of these are 272 degrees), and maybe even the GTM stage 3 cams. Also, to run those rpms, you should probably have a billit girdle.

The GTM stage 2 cams have less lift than the BC stage 3 cams, and thus will have less lift angle, which is good for high rpm operation. That said, I believe others are pushing the BC stage 3 cams to 8500 rpm, so I think those cams will also work, and the additional lift should provide a benefit. The GTM stage 3 cams have close to the same lift as the BC stage 3 cams, but quite a bit more duration, so these should really shine at high rpms. The big concern with high duration cams is their lopiness at idle and low rpm. I have been told that the GTM stage 3 cams idle fine, though. Perhaps Sam can steer you to a video where you can listen to a car that has them idle.

 

r u runing 750CC injectors ???

i like to know the Duty cycle, and allso how much timing ur runing.

those turbos should make more hp !!!

allso there was a DE engine with the STG 4made 682 whp on a dynojet with 19 psi and 109 oct.

still the number for a STG4 is better cuz it made this power with les boost.

i dunno what to say, if can SAM clear this for us GTM turbo kit owners.

 

^ low attention span?

copied form page 1 of this super long 3 page thread

 

I originally planned on doing a 116 octane tune thats why i was originally aiming for a higher hp number. Things changed and I went a different route.

Smalltuner, you are comparing dynojet numbers to my dd numbers which is basically apples to oranges

If you look back at shop builds and see wongys g35 put down 639 on injecteds dd then put down 719 on a dj

I would say my car is well into the 700s on a dj

I will look into changing the cams but probably won't for a while. After missing out this whole year I plan on leaving the car alone and driving it next year
