My plan is for a 2 1/4 mandrel bent coming off genie 4-1 extractors on what id say will be a very hot a15. (not very very as in total race) Im opting for the 2 1/4 because i belive you get a better note rather than a big blurt that a 2 1/2 gives out plus id rather the extra room than having a bigg 2 1/2 running over the diff.

My mildish a14 i believe is quicker than commodres and sixes as a street car. May not be over the whole 1/4mile but street wise i really believe so. I drive a commodore to work everyday and the 0-80kph is really poor compared to the datto. Ive said before it jumped my mates 185kw v8 commo by a decent amount before been wound in. I miss the datto drive to work everyday. Zip in and out of traffic and pull away effortlessly beating other cars. Not to mention those tight situations where you just nail it in 1st from a intersection to beat traffic. If i did that in the local six id have a nice impression of another car of some sort in the side of the car. You'll be very happy when you drive this thing if you think the a12 is nippy. This will be blinding in comparison.

I have to agree with Freak, if you think the A12 is nippy this will be blinding in comparison.

With my hopped up A15 I leave those locally built sixes like they were parked, in fact its only the WRXs and real hot V8s that ever beat you at the lights.

wow thats pretty immpressive! I thought it would be a bit chunkier but had no idea it could hang with a 185kw clubby, I hope my old 4 speed and diff will last a little while
