Stock Headgaskets

[NebTurboST5]

how many lbs of boost have people pushed them too? i think i remember reading 22-24 lbs is max is about it. my car has head studs in it. just curious as im going to order a new wastegate with an 11lb spring so i could run upwards of 22 lbs. i currently run 18 with 18* of spark advance and havent had any issues.

Run em.

[NebTurboST5]

Run em.

planned on it as i dont plan to tear it apart. just curious if anyone had any experience on high boost.

The guys from Canada has run up to 30 on completely stock motors. I don't think you'll have a problem especially since you have studs and your car is slow.

Im not sure what you would switch to. I sent SCE an email to try and get info from them, but they are difficult to get ahold of.

MLS are stock head gaskets on the 3000GT/Stealth's and also DSM's. There are many, many guys running 20+ psi of boost and still lots of others running 35+ psi of boost on the factory MLS with no issues on those platforms. It's odd that the 3800 platform would have issues with them, unless there was some sort of manufacturing defect or something else causing the failures/issues.

I think stock is probably better than those.

[NebTurboST5]

no doubt.

Ive had MLS with less power then I have now and they blew. I then went with stock. Worked much better. I just blew my stock gaskets at 25 psi due to cracked heads and also my engine not breathing enough. I only have a rear PEM which i'm getting rid of. I have new stockers ready to be put back on.

I forgot who but he ran 28 psi on stock gasket.

holy **** i just realized that my car trapped almost the exact same MPH as yours. my pass was only an 11.57 though. it was a turd out of the hole.

[NebTurboST5]

good info thanks. i think im gonna run a 11psi spring in my car so i might turn it up to low 20's

Sal's car didn't accelerate for the last 330' that's why he only trapped 122 lol

any particular reason he shut it down at 990'? i guess i was just excited. if i could get a 1.74 60' out of my car it should go at least 11.4x

AFR was 16.0+ or something and was making no power… think he sucked the canister dry.

[NebTurboST5]

ouch...

[Silver2kgtp]

Yeah the car just lost all power and fell flat. Like Nick said canister was sucked dry. E85 saved my bottom end.

Seems like stock GM gaskets are the way to go.

[GTPpower]

If you get some real tires on the front of that thing, you can cut big boy 60ft's.

I'm gunna be running 24-25lbs on stock felpro gaskets And head studs.

[NebTurboST5]

i would get the gaskets from GMpartsdirect not a parts store. i have seen the felpros from a parts store fail quickly
