From what I've read on forums the guy is perfectly happy making baseless insults about anyone online, even admins. Others say that he is really nice in person until he gets your money. Then he uses your money to buy a home and doesn't finish the car.

 

that sucks, you hear so much about his cars and then find this stuff after idolizing his work for years

 

Hennessy is very expensive, and many people had negitave feedback about him. I had a friend who bought a JEEP SRT8 Turbo from Hennessy, and it was just a BS for the price he paid!! $27K for turbo kit...its for nothing!!
others tune/mod thier cars with less than $10K and their cars are faster than Hennessy JEEP SRT8. you may check at Cherokee forums.

I would not buy from him a single part. I would rather keep my GTR stock if he is the only one in the world to mod GTRs..

Plus since when he knows about GTRs? its just BS

lets wait a bit, and i am sure a good tuning shops will come back with many things for us.

 

those guys do good work, i've always been a fan. Can't wait to see what they come out with for the R35

 

Ok so my point exactly. What do I do if I want to make my GTR run faster - Hennessey, setting aside the rep, wants $37,000 to basically change the turbos, change injectors, add a mid pipe and exhuast system and reflash the ECM

How do you make these cars like 50hp better without spending 20% the value of the car?

I dyno'd mine made 400 and 400 3 times in a row
