right i've just come back from a local track day and i was extremely disspointed with the performance of my frst... the best run i could manage with a extremely good start was a 16.2 with the following spec 1.8zvh, worked head, beige injectors, t3 conversion, double pace intercooler and 195 chip.

i know the chips not really suitable for the zvh but its been set up and works fine. what sort of times for the spec are anyone managing? i had a standard erst and could manage a 15.9! fair enough it has lsd but my starts were just as good with the frst to be honest. i even had a veteran track day guy try and he could only manage much the same..

would i be better going back to a 1.6cvh bottom end instead of this zvh? any ideas/advice much appreciated i am on a udget tho so cant go for massive zetec turbo full conversions etc! lol

Problem with the ZVH is most people that build them don't bother working the head correctly and as a result power and torque tails off sharply at about 5krpm. I would beinclined to Ian Howell a shout at Area Six and get him to sort your head. What cam are you using as this can play a big part. If it's a Piper 285T2 this will only compound the problem of the head. If the cam is standard is it healthy? A bigger intercooler would certainly help.

so it turns out that the chip is completely wrong for my engine...... so now im gunna get rid of the zvh and build a cvh from scratch as im not to interested/afford a full zetec conversion. cheers for the advice
