I apologize if this has been discussed before, but I was just doing a little research on the Greddy TT and it was just brought to my attention that it is putting out about 335 HP to the wheels. Now I read the motor trend article and apparently they were able to achieve 12.79 1/4 mile time which is awesome. Now I have been seeing on some of the forums that people having the Procharger (with about 368 HP to the wheels) are getting low 13s and the occasional 12.9,12.8. So could it be there is more power coming out of the TT and they didn't post it, or what's the issue. I was looking to get the Procharger, but it seems like a lot of people are having some problems, so I am thinking of waiting for the TTs. Obviously price is a lot more, but oh well. So what does everyone think could be the issue with the lower TT times?
ASWELL, I know one or two of the people on the forum have ridden inside the PE TT (maybe even driven it), how does it feel compared with the Procharger?

 

HEY THAT IS A GOOD OBSERVATION! ...interesting :P

 

what are the MPH's being achieved? trap speed generally tells all...not the ET.

 

It is just the difference in boost between the TT and SC. The TT reaches full boost at like 3-4K rpms. The SC never reaches full boost til the redline. There is more area under the power curve with a TT, even if the peak power output is advertised as the same.

 

The ATI Procharger has been trapping speeds at around 104-105 or so. MT got the TT Z at 106.5 mph. I am not sure about the Stillen, but I assume that it is much less.

 

Spot-on.

 

also. the greddy TT lays down 340lbs of torque while all the superchargers is around 300. so the TT will give you better 60' times.
