09/11/11 Rolling Road Report

Finally we decided to run the GT4X on the rolling road, its been 5 years since the last run and we were intrigued to find out just how much power the car had. The car is very difficult to dyno test and we encountered wheelspin throughout the runs, despite this we recorded 743.9 bhp without nitrous and 548.7 lb/ft torque. The Nitrous adds 75bhp so making 818.9bhp is a fairly conservative estimate :)

Fensport GT4X 4wd turbocharged 3S-GTE with 818bhp


Having created the UK`s fastest Front & 4wd wheel drive Corolla`s, we decided it was time for a change in direction and try something new, but we still wanted to retain that "shock factor" that our corolla is so famous for, so we decided to build a celica - the new celica, the generation 7.

We wanted to create the best all round track / drag celica the UK has ever seen so we started with the generation 7 TRD M Sport. This limited edition special model is factory strengthened for motorsport use, making it an ideal base, it is also much lighter than the previous celica gt4 models .

We started the theory side of the project back in august 05 and started measuring and working out what parts may fit or be required. Then in October 2005 the real work started with delivery of the car and the very first job was the 4wd conversion and the 3sgte engine installation, this was acomplished using a variety of standard toyota parts from the celica, the 4wd corolla and the GT4.

The car has been built with all round performance in mind, it will compete in a wide range of events including Ten of the Best, Time Attack and Drag Racing Events.
