I will be bringing another GT1000 Twin Turbo SC to the Houston Cars and Coffee tomorrow. Hope to see some of you guys there.

How about using an empty blower housing just for effect, would that make everything easier? Less power but maybe less problems.

The solo picture shared has her looking very nice; John is there a chance that you could/would post a few more of the engine bay and how the combined system was integrated within?
In addition I would like to ask a few question;
1. Is this gal tuned for 91 and assuming so when under power/load what sort of discharge air temps are you seeing?
2. Are you using headers or a connecting pipe from the OEM maniolds back?
3. Have the cats been dropped from the system and if yes then did you try the system with them and if yes did the spooling of the turbos fall off greatly?
4. Your web site has some great information and videos however I was unable to find much information on this system; can you share a link direct to the information applicable specific to this or a similar gal?
Thank you and all the best

Hi John and thank you for the reply
I will await the additional pictures because they will likely answer most if not all of the remaining questions that come to mind.
With regards to your comment "It makes great power, looks good and is reasonably priced plus comes with a warranty; what else is there to know".
I agree John that these are items worthy of being shared however IMO are simply a reflection of the package being offered and your feelings rather than the description of the package itself.
I mean not to put you on the spot in any way but rather I am as are many a "nuts and bolts" type person and we like to know the mechanical aspects of such a conversion.
Takes care

John,
Thanks for sharing! The pictures look great and I have no doubt that it has the perfromance to match!! Man, I thought Don's car was nasty, but this one has to be an absolute beast! Now, don't forget to hang one of the coolers on to protect that transaxle. :biggrin
Kumar, I think the answer with respect to preference of TT or TT + SC, lies in what you are trying to achieve. If you inspect the dyno graphs of the big Whipple cars with those of the TT only, you will notice that the Whipple has almost a 200HP advantage at ~3000-3500 RPM. Although the turbos are spooled and starting to generate boost at this RPM, the "Saturn 5 - like" boost hits from here on out. I think this near vertical power segment in the TT cars is what makes them so infinitely enjoyable to drive.
You may recall that Jason experimented with TT+SC when building the GT that won the 0-200-0 magazine contest last year. The presence of the SC eliminated this 200HP low RPM deficit (compared to TT only), but on the top end the SC is "consuming" ~100HP as the engine spins those twin rotors. For the best 0-200 MPH time, Jason ultimately chose a TT-only set-up sense top-end power was so key to his objectives. (Interestingly, after a lot of different experimentations, Jason ultimately used his "normal" TT SC kit :thumbsup)
At the significant risk of over-simplifying;
Whipple SC: OEM-like linear, albeit higher, power from the moment you press the throttle.
TT: Good power followed by Saturn 5-like vertical power curve... timed pretty much when you would want it (otherwise you are just shredding tires).
TT + OEM SC: Stronger low-end power (watch those tires!) with a theoretical imposition on the top, top end... which you may never experience in the real (sane) world.
TT + Whipple: Shot from a canon, and then light the after-burners :eek (In reality, this combo may not be practical.)

Has anyone done a TT+Whipple. As i understand it Heffner does not recommend this and he would only recommend a tt+stock blower. The whipple takes more power to run than the Stock blower, plus you would need to turn the whipple down to make the combo work properly so at that point with stock like boost and the whipple it would probaly make less pwer down low.
Maybe some one has done and and has some info.
