Are you talking about static or dynamic comp? with a correct tune, and modifications to the combustion chamber, an extremely high boost/compression can be had, without detonation they are boosting ls1's with turboes, twins, and chargers, all with standard internals (so 10:1+ comp)

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 14.3 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. If you made 338 kw im sure you could of scraped a 12.... Got some proof ie dyno sheet?

What n/a records have maatouks suddenly smashed???? have they run quicker than 9.9 on a unopened na motor?

u soon baset Some original photos have not been recovered yet.

my mate is currently building his vl 180k's standard N/a RB30 bottom end N/A auto (shift kitted) 3200 stall,tranny cooler GT35/40 550cc injectors microtech LT10s Cometic Headgasket 38mm External Gate bosch 044 pump surge tank 3inch turbo back zorst etc etc he's hoping to see into the 250-300rkws zone he wants to know if its a big ask from it but personally i think it should be fine considering all the other ppl that have done it

if using a gasket that lowers compression to ~8.5:1, is it better to keep the na pistons, or put in turbo pistons? would gasket hold ok with that compression, don't want to take off head again and again. also are turbo engines slow off boost?, i am used to my vlt high compression engine

Good work mate, really relevent post and some good encouragement to the people in this thread that have little money and are doing their best EDIT: In case it slipped your eyes, they are talking about NA-t record, not a normal VL turbo record, as in stock NA pistons or stock NA bottom ends. I doubt the maatouks cars are either. 6BOOST Some original photos have not been recovered yet.

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 just a question for you are u talking about the red berlina or exec witch ever one it was? is this the car http://www.nizpro.com.au/no_laughing_matter_main.html Some original photos have not been recovered yet.

any pic's mate?

I can't wait to see what it pulls this weekend Scooter, I'll be there to spectate.

well currently i am running a totally stock rb30na havn't done anything to it other than bolt my manifolds to it it's been sitting in the shed for 4 years and was seized 4 hours before we started it have currently run a 12.9 with street tyres, next street meet is next friday, let u know how i go then it's a bit smokey through the breathers but exhaust is clean as a whistle, and has a bit of blow by at the 10psi mark but other than that it's great, just spent 2days on a car rally floggin the **** out ot it, (and nearly emptying the sump) had to put 4litres of oil in it on the Sunday before we started racing again. i think it will be my best motor yet so the setup is as follows totally stock na rb30, un opened 100k plus cpc manifold with 6boost injectors 6boost gt35 kit standard coil wolf 3d jet automotive auto Some original photos have not been recovered yet.

Quote: Originally Posted by Raptor Yeah I think not, he just got rolled hard. If not im in trouble. raptor i think hes talking about the manual records, rajab ran the 9.9 in a auto i believe. Correct me if im wrong its just from what ive read.. Some original photos have not been recovered yet.
