Awsome MR.Squezze, Great write up.
Glad you final got her back , Numbers are GREAT, Nice choice, Sounds good to. Waiting for that 3 inch :)

[QUOTE=Mr.Squeeze;1906768]My Twin Turbo built motor car has been through a long proccess getting everything together. I received my GTM stage 3 GT3071R turbo kit on May 22 and started to install it my self. Because of time and some issue's I could not complete the install my self. So I called up my friends over at Real Auto Dynamic's in Long Island N.Y to finish the install for me.

Car has the following parts.
Wiseco 10:1 custom pistons
Eagle Rods
ARP L19 Head Studs
New Stock Head gasket
Deatschwerks 850cc Injectors
CJM Motorsports Twin fuel pump
CJM fuel Return system
GTM fuel Rails
R/T Tuning fuel feed lines
HKS EVC S boost controller
Two AEM Widebadn Gauges in the Cuby
DEfi Boost Oil Temp Oil pressure in Stock location for a OEM look
South Bend TZR Stage two clutch Rated @ 700 RWTQ


are these parts just added on for the stock block or was a new engine installed.

[QUOTE=Dre370z;1908916]Stock motor was taken out the car and built with the parts in the list.

Most car's on Stock blocks with smaller turbo's dont seem to have a problem at all you should be fine.

Congrats again brother!

Cliff,

Congratulations on getting the car up and running. Looking at your dyno graph, it does look like a classic exhaust restriction, especially when you get to the high rpm and instead of the power continuing to climb, it gets wavy and starts to fall off. The .64 A/R housing you have are capable of 700+whp easily and I'm being conservative. We have done more.

I'm posting a couple dyno graphs for comparison. Both these cars have built engines. One of them is a VHR with our Stage 2 (GT 2860RS with .86 A/R). As you can see, we're accomplishing 608whp at 15psi of boost on 9:1 compression. If you are at 19psi with GT30's with 10:1 compression and only at 613whp, either you have a major exhaust restriction or something is not right. It is not a turbo sizing issue. Also, another way to look at it is that if the dyno graph did not fall off at high rpm, then I would expect you to be at 700whp at the same boost level.


As for T25 housings being small, remember that this is a twin turbo setup, not a single turbo. ;) You can't look at these dyno graphs and still say that the T25 housing is too small.

Sam

Nice seeing those graph's Sam that 14 psi Stage 3 is really what I would like my car to make at that boost level.

Good motivation right there.

Hey cliff....thanks for the good words. Look forward to getting this where it should be once we get that exhaust on there!!!!



Hey Sam, the second graph you posted with the GT30's....are they with.64 or .86 housings?

Looking good man! Amazing numbers!

P.S. Your old exhaust is enjoying it's new home :D

I cant wait to get the car back down to once I get the exhaust.


The thing I love about the car the most is the way it drives the car run's great love the tune.

^^^^thats good to know... That link is to a car with 272 cams which kinda skews it, but is goodmto see for comparison. Do you have any dyno graphs of stg 3 VHR motor?

midrange was laying out nice but up high was def suffering. Once Cliff gets the exhuast he is waiting on I am confident everything will lay out like it should

Thanks for the quick reply

New numbers with Fast Intentions 3 inch exhaust
Low boost 14 PSI 596 Whp 546 TQ
Mid Boost 17 PSI 631Whp 600TQ
High boost 19 PSI 647 Whp 613 TQ

WOW man congrats, Great build man!!!

Very nice!

Thanks man it's been a long road to get to this point ,will push for 700whp on E85 next year . I will post the graphs once I get the files from Vince on Monday .
