would the hot side of a pt 101 with a 1.0ar be to small for a 400sbc at 7000rpm? also would the decks on my dart 2's be to thin, they have been angle milled to 57cc from 64? for my 1000rwhp plans.meth fuel and would probably prefer not to use these sorts of revs but just love a sbc at 7k+.top site thanks heaps

I was told by PTE to start with a 1.0 on a 400ci SBC. But the more I think about it, I should have gonne bigger. This is on G trim wheel. F trim Im told spols a bit faster.Im basing this on what other Turbo guys here run on 400ci +in motors to really know.. Hopefully ill be making passes in the next few months.

The 1.0 A/R should be perfect for what you're trying to do. 1,000 RWHP won't even be working that set-up. I spec'd a 1.0 A/R G-trim set-up for my own 400cu. engine that can turn 8,500 rpm.

It is a good starting place. You can expect to end up in a larger AR. Back pressure will tell you everything.

johny a freind of mine can hook u up-he is in australia if u are?

he gets a bit of pt stuff from time to time- price is pretty good-

he only sells new unit's

$2700.00 seems a bit high even if its had 3 hours work-its still s/hand

up to u i guess-

whats the sellers reason for selling it-

pm me and i can past it on

Thanks

The high price is because it's a Turbonetics turbo, not a Precision. I have a 101mm Turbonetics for sale as well, selling it due to dropping down to mod st (88mm) don't have the $ to compete with the Pro St guys.

To be up the top in Pro St means a full on package - not only engine but chassis and drivetrain. Mod St can back it down a fair bit - just on engine alone with maintainence Pro St looking at Tit/Inconel valves, bigger spring rates, alloy rods. Mod St can run steel components and a smaller cam and still run near the front. Chassis is another massive area, check out the breakages just from the cars running a couple of weeks ago at the WSID bracket meeting. Mod st cars pretty much came away unscathed, Tristan's pro st capri is going to need some serious $ thrown at it to repair it from the wheelstand. Another Pro car is looking at a hefty engine rebuild, and yet another Pro car is getting a new shafiroff motor to get to the top. Mod St cars.... well I know Kryger is looking at another.... set of tyres! Big diff in operating costs. At the Brisbane event I know another Pro car is looking at a big engine rebuild due to valvetrain failure... again Mod St is alot more affordable.

Oh and with regards to the failure rate of Turbonetics gear.. I think it happens to all of them. Heck look at all the threads about the new billet Precision gear failing.

hey cb75,pro st and mod st,imo. pro is a car that can put the pwr down,and mod is just another half or standard chsis car with to much hp, Steve Athans in pro street has no probs,basic 23% 350chev,internal gated dryers,primative(so they say)mech injection and yet dollar for dollar,and mph is the fastest in aus by far! with no tit valves or alloy rods to be seen! just wait till he turns up the wick(he already has 1470 rwhp)

I'm not running my junk in an ex-pro stock car like Athans. Big difference between a street car and a pro stock car. The new cars appearing are pretty full on, I cannot and will not compete with these guys throwing hundreds of thousands on "street" cars.
Campisi is quicker by over half a second on Athans, and his new mustang is going to be pretty damn quick. Heck even the naturally aspirated cars are quicker than Athans now. I know he has a good low maintenance combination but he's not at the top or will be within a year at his current level. I'd like to see him turn up the wick, will be interesting.

i am sure if someone gave steve all the tricks of camps car(the best ford has in engines,efi ect) and he only picked up half a second and a few mph he would be realy shited off,and buy the way steves car is an all steel ex super stock car.nothing like a pro stocker. but compared to a cortina i can understand your confusion
