Pace double capacity can't cope with anything much above stock boost. I ran one on my old spec at 18psi and it was seriously underperforming. I made 199bhp on the rollers at SCA in Norwich and the operator commented that the ACT's were off the scale. Even running it alongside water injection didn't drop th etemps to an acceptable level. Since fitting the full width Pace I now run the car at 26psi and the ACT's never seem to exceed 40°C unless I'm being an animal on track.

Honestly mate I would recomend you do the job right first time out and fit something like a GRS/Radtec/Pace full width or even an Airtec front mount. There's nothing more annoying than having to pay out a second time because you purchased the wrong kit
