might find its running more on the charger side not at the inlet itself, boost will drop across an intercooler.

About 19 PSI is right - it does vary though, and is mainly dependent on cam timing and exhaust system.

How much quicker is it in real terms compared to low boost Ben? Never driven or been in a high boost.... My low boost is quicker than most of them and a lot of people have said for the extra expenditure they weren't that impressed?

Also worried about blowing gearboxes up where as mines reliable as can be at the minute.

To be honest pete, im not sure as of yet. I've only driven it in the p**sing rain and damp so not had a chance to really see what it will do.
When it grips in 2nd and 3rd, its evil.
Almost cant change gears quick enough in 1,2,3rd while 4,5th you dont spend much time waiting to changeLOL
The only downside for me is the paddle clutch is a pig. All the other stuff is fit and forget just like lb.
But from the few times i have opened it up, i knew it was worth it.


I managed to get brake fade on my rs310's the first time opened it up to Sad

Need some 330's now then LOL

I've had a few lads that have owned high boosts say to me when they have blown 3rd gear it was because of wheelspin in that gear as it suddenly bites after spinning they went boom so I'd try to avoid that if I were you Wink

Not much left to do to my car other than more power and track tyres so I still may yet go high boost. Got pistons rods swirl pot and pump so half way there....

That's where a plate diff will help over a quaife, if you're daft enough with the pedals a quaife will just let you spin a wheel right up.

a plate will bite and you'll spin both wheels if you have that little grip.

Nah will change the pads as i put standard pads in last year which are now not upto the job.
The minute it starts to spin, i let off or change gear anyways as spinning only leads to problems.

Believe me mate, thats not half way there. Its all the little bits you dont think about that end up setting you back.

Atb will be fine. Mine never spins in 3rd. But that could be due to the gearing i use. Be nice to see a high boost actually going.

Nope - It's been road legal for a couple of months now, just haven't bothered with any shows this year.
