so on a tangent here, a colleague bought a used hennessey gtr700. I looked online and i guess it has new turbos and intercoolers, plus a tune. No transmission work. Is there likely to be a transmission problem? Thats a lot of power, but then again, the NSX transmission seems to take 500 rwhp just fine for quite a while... and the ford GT transmission holds 850rwhp no problem.. and the supra holds 600 no problem..
BTW: If your colleague bought a Henessey GTR, he might want read this thread if the car has not been checked by a reputable tuner already:
