mmmm, Looking at this thread, I'm wondering if anyone has worked out how thick the gasket/plate would have to be to get the comp down to what it is on the standard VLT motor ?

3mm? but we dont want to lower any compression, high comp FTW

higher comp = less boost required yes/no? low boost needs more yea? I once read on this forum 3PSI= 1 point in comp, so in saying that wouldnt a high comp engine running less boost make the same power on less boost ????? All in the tune detonation is the killer of all engines N/A or othewise Some original photos have not been recovered yet.

Thats correct, more power on less boost, Methanol injection helps to bring down the intake temps to stop detonation, so if you were wanting to run high boost on a high comp engine then Methanol is going to help.

I want to chase the N/a highcomp manual record. haha! just to be diff from you bas! Ill be sourcing a new turbo / injectors soon as its slapped together.. E-Z how much was your turbz?

looks like methonal is the way to go for the high comp setups. lol bogz thats alright man, what turbo you llooking at getting? i think im gonna be getting a packege from kyle soon, just give me a couple of months for saving, then ill see what turbo i want, but i want a big fcuker at that. for now ill stick with mine and hopefully crack a good 12 second pass

I dont know yet, im getting a r33 box asap. and lsd center! Do you still have that one?

I helped john (304CID) with some of the component selection on his 10 sec calais. The car had little more than a standard rebuild including the stock NA oil pump(higly unrecommended!!), pistons rods and crank. It had no port work as far as I know, just a tighe cam, valve springs, head studs and a .073" cometic head gasket, the turbo side was a old school plain bearing HKS T51R(no not their new looking ones, think 90's style TA45) on one of my manifolds. The car made 315-330rwkw from memory and run a 10.87 on its second outing on avgas. I believe it ran low 11's on straight pump, but he never pushed the setup too hard as he always intended to sell it. Rajab racing built a car years ago that was in zoom that had stock NA pistons and rods in it that went 9.9, so I'd say you'll have to beat that time for the record. High compression is ok to a point, but anywhere in the 9's and your asking for trouble on pump fuel. Where high comp is starting to get common place in big hp engines is running C16 and the like where the octane of the fuel can support the detonation threshold of the compression and boost your running. Forget trying to run 10's on pump fuel with stock NA compression. Unless you have spares, or like rebuilding often For the record, Cometic make multi layer steel gaskets for the RB30, their .073" head gasket gives roughly 8.6:1 comp, which I recommend as the best all round compression for both pump and race fuels, and they have a 3mm head gasket which drops it to the factory 7.8:1 compression. Both work equally well as a decompression measure AND a head gasket, no more dodgy blow outs with spacer plates and the like. 6BOOST Some original photos have not been recovered yet.

what constitutes high comp? Anything over 8.0? 8.5?

above 8.5 id say. but really talking bout the na compression, not sure if its 9.0:1 ?

9.0:1 is stock non-turbo compression

I will be running an NA with cam, ported head, GT35/40 & a 3300 stall on LPG. Although I may cheat later on adding a cometic multi layer head gasket Some original photos have not been recovered yet.

I still dont know of anyone who has made more than my na ****ter! 338rwkw unopened na bottom end with 200,000+ km on the clock and i still run a standard ecu and injectors. The methanol does help through the other 6 injectors welded into the bottom of the inlet runners!

I has a couple of things done to it, runs a 1147c wade cam,the head has been ported, valve spring, ****ty ebay t70 turbo with a crappy manifold and waste gate. i had a inlet manifold made and it very similar to the rajab cast one. I run a acl 3 layer stainless head gasket and there is a set of ARP head studs holding it together. I did run it down a calder a few months ago on street tyres. Ran a 13.3 at 120mph, i didn't really get any traction till i threw it into 4th gear. I was sort of happy with the mph considering the traction problems.

I was sort of happy with the mph considering the traction problems. very impressive man, sounds tuff as. one thing, you got a 3 layer stainless gasket, so that defeats the purpose of high comp, as that will lower it to standard turbo compression wouldnt it.? also, dont the standard injectors at the very max go to about 220rwkw?

Some original photos have not been recovered yet.

Hey Bas, My mate's car has stock N/a internals and is running a decomp plate and his cal's T3/4 see's 19 pound everyday. Ultimately low 12 to high 11's!
