Possible build? 90 psi 2.2 ecotec?
Car throttle has an issue top 10 super sleepers. That's were I seen the vw. YouTube or Google it it should still be around. And yes I've seen that badass fmsr head... But I'm worried why are they the only ones that can make a head that pushes 60 psi + ....
Now someone please tell me I got my number wrong but if my blower is going at 20psi and my turbos kicken in 30 I don't actually get 78psi do I?

Boost pressure is outlet minus inlet. If you have a single charger, then it's output minus atmospheric. You don't get to count atmospheric twice. It'd be 64.5psi.
HOWEVER, that's assuming you get to maintain the same efficiency. You lose so much efficiency doing something like that, that as others have already said it's not worth it.

Pot Lol idk.... And no realistically 500 hp - 800 hp torque somewheres near the same range... I didn't say I wasn't getting alot custom work done to it...
And so my psi calculations are close. Then ?

The only thing I stated was I seen an mk2 gold with 2000 hp which is ridiculous. I want something that would keep up or smoke a corvette. Any ideas fire away.
Why will I not run nos... Even with safeties there's a greater chance at hitting it at the wrong time. 6 grand out the drain.
Why will I twincharge it... Turbo lag I had a car before with a t2 t3 turbo I put a turbo out of a ford diesel one ton... And turbo freagin lag man... Big time turbo lag. But once hit 4700 rpms, you hit 6200 rpms in a split second.

Alright since you guys ain't helping me get anywheres.... I'm gonna stick this to local build. And when I'm finished I'll take some pics and vids. But I won't go into the detail of work I've done ;-). You fellers have a good one

ZFR (ERF modified housing) LNF cobalt was reeling in a Mclareen MP4-12C from 100ish to 160ish. A stock e85 LNF will beat down C6 corvettes at the track with a good driver behind the cobalt, learn to race first then build power, power won't win you races.

It's not that no one wanrmts to help you or give you advice but when you start talking about 90 psi + an ecotec **** was bound to go down hill. Personally for your goals I would run a single turbo s259 and it'll get you to that range. Talk with the other turbo guys who run it and they'll give you an idea of the lag.
A twin charged build would be epic but I can only think the supercharger would be more of a restriction once the turbo takes over at x rpm unless you had a way to bypass it after a certain rpm. All well above my knowledge

I think you (op) need to read the ecotec build book so you can get an idea of what your asking.
Also take a look at rollermandans build thread and associated threads to see what kind of car it takes to handle the type of power you are referring to.

Btw zzp "only" needed 55psi to make 898whp which i believe is rhe highest recorded whp on a production ecotec block

So I'm curious to all the l61 owners I'm thinking about starting a build is there anyway to build an engine with 90 pounds of boost. My guess probably not. If I did build this what parts should I be looking for to handle 90 psi of boost. Plan:
Engine bored 30 over bore.
Eagle rods and bearings
Wiseco pistons 8:1 compression (drop in compression)
Billet crankshaft 4340
Supertech ported valves
82lb springs and retainers
Valve seals (no idea yet)
Competition camshafts (strip cams or racing cams) not fully decided.
Now would I need to have a Darton sleeves installed. What should I be looking for to push 90psi. (Actual psi 80) but 10 just in case anything goes bad. Will I have to nitro it, or could I use high octane gas. 97+?
Any info would be great considering I'm starting this ridiculous build soon.

You think the tvs will make 90psi?
