Al_Galone Unregistered A	Can everybody list their times on 402m and please give us your modifications. My personal best TT is 14.205 (and I am not fuc... pleased with it I think it has to go little below 14sec) I am trying to find out what could be stoping my car to break the 14sec limit,becouse when it was a complete stock it run 14.35x seconds. I have a custom decat straight trough exhaust 60mm,K&N panel filter with drilled airbox,K&N air breather,Baileys DV36 BOV,Gtec1,manual boost controler set to 1.2bar,new turbo with 360 degree bearing,stagered seals,and a bigger compresor wheel,modified comp housing,Walbro 255l fuel pump with wiring mod,Good year Eagle F1 tyres 205/50/R16 on 7,5J rims with 16mm distance plates. Complete turbo and IC system isnt leaking anywher,boost is holding prety well almost to redline, I am not sure what to do next. I know best way to go is to go on RR and check everything,but till that happens any opinions??? Last edited by Al_Galone; 08/09/2008 12:34.

Over here a lot of people use Santa Pod for the 1/4 mile. It's used for top fuelers so the strip is not your average tarmac! It'd be easier to get a better launch (and time) at the 'pod than at an airfield. As Nigel said what is your 60ft time?

I am sure that we all would have a better times if we would have a better tarmac,but since we dont,I have to find some other way.
