how much hp/boost can a built lt1 take?

INTIMID8 is pushin like 800+ on a twin turbo LT1 that runs 9's. If it's built right, i'd say it can support the same amount that an LS1 can. Expect to spend lotssss of $ though.

i've allready got a pt88 and juise, but i am going to a turbotec.ytk88 over winter,and this is a street car still. anyone got anything bigger or simular?

rick intrau has like a 98mm or something like, full blown race car in the high7's low 8's, i dont know if youd consider that similar

yea, this car has to still be a street car too!

I've run up to 24 psi and pulled 146 mph in the quarter at full street weight using a production LT1 block converted to 4-bolt mains. With a half-fill, you can run Rick's numbers. I did have an overboost incident where I blew both head-gaskets but nothing else was hurt.

this caught my attention. alot of LS1 guys talk about their heads lifting at really high power levels. there aren't too many LT1 guys up there but the engines are very similar to a SBC. at what point does a SBC start lifting the heads? I honestly think it would be at a higher pressure than an LSx due to 5 cylinder head bolts per cylinder rather than the LSx's 4.

a strong 383 LT1 with ported trickflow heads and a good sized turbo would be very fun

Any pics of your setup? What kind of numbers were you already making?

engineermike

zigroid, I thought that statement was funny too. The common logic has always been that the LSX can't take as much cylinder pressure as LTX/SBC due to the reduced amount of head bolts.

the SBC can definitly take more cylinder pressure than the LSx (up to the new World/GMPP **** though)

how strong are the LT1 block castings though?

engineermike

Strong enough to go high 9's / low 10's with a 2-bolt, low 9's / high 8's with a 4-bolt conversion, and low 8's / high 7's with a fill.

no real data or numbers but we guessing on 950hp to the wheels maybe more. my home made kit is real simple old slp headers swapped side to side, and y pipe run to the turbo mounted in upper left front cornner of car. where the abs used to be. and a custom radiator. it was a air to water," which my whole intercooler kit is for sale", but now im going back to air to air.

how is the haft fill for the street? i heard not to bother will it.

I am running a half fill on my late model GMPP 4-bolt block and it is fine on the street. I'm running the Evans waterless coolant and Redline synthetic. Cooler coolant and warmer oil is good for HP.

Once I hook up the 2 stages of nitrous I expect to easily get into the 700's for rwhp, and the 800's for rwt.

ARP main and head studs. 6" rods, all forged, good balance job at 6200 and a Fluidampr all help make a smooth, strong and safe setup.

From what I've read you should be looing elsewhere for a block at the four digit rwhp range. As I recall, George baxter had started to see evidence of the block flexing at more than four digits. Nothing has been created to solve the problem as far as I know.

Many guys have said this kind of power is comletely and totally useless for a street car.

yes you can't launch on the street with that power,...but you can bring it on in 2,3,and four,and drive by the guy! plus on the street they are typically at the same disadvantage on the launch. my car, on a day when the roads are warm, will take everything my pt88's got and some no2! except in 1 gear and some times 2nd
