Well i`m booked in on saturday for a rolling road shootout!

My setup is:

Stock Gti-R motor, Stock T28, 444`s, Walbro 255, Front mount, HKS Musroom filter, 3" all the way from turbo outlet to side exit, JAM Racing ECU, running at 14 psi, timing 20*.

What sort of power should i put down?

I will post graph if i get one!

250-275whp??? Make sure everything is in spec. Compression, Spark, fuel pressure, timing.

I will be happy with that. dont think i`m going to get time to do a compression check!

I have replaced the rotor and cap and gone back to OEM leads, running brand new ngk7`s left pre gapped.

The car feels healthy as at only 10psi i had no problem sticking to the ass of my buddys TVR t350 and trying to overtake! :biggthump

The only problem i know my car has is a torn CV boot and a tranny drip :(

you might need to bring that gap down a little.. im not sure what they come, but i would think between .28-.30 is where youll want to be

Do you mean .028" - .030" ?????

I get really confused with plug gap figures :confused:

I was told the spark plugs came pre-gapped. They are not. Check them!

I just re-gapped the plugs to .030" they had to come down a little but were fairly evenly pre-gapped.

It seems to be a little smoother through the revs than before at 10psi.

I`ll leave the gap at this for the dyno run and see how it goes at 14psi :)

Took it out for a little pre dyno high boost testing and wow i love 14psi :biggthump

It feels so much better than it did in my Gti-R, prob due to the transmission losses!

I hope it all stays together for the run tomorrow!

Wish me luck! :fingersx:

I am guessing 282 with it tuned right! Hopefully I will be within 1-2 HP!
