Water/meth would help, but two compressors make an awful lot of heat. One turbo at 35 psi discharges at over 250 degrees. Add another one on top of that and you are going to see 500 - 600 degrees in the manifold. That's really going to hurt density.

I hear ya on the compression. Not the best thing on a cold morning, but it helps keep the HG alive with a lot of boost.

 

so what your saying is lower compression pistons would be better, but i don't really need them, im just conserned about blowing my hg at 60psi even with the o-ringed head, by the way how much does it usually cost to o-ring a head?

 

hey just a few more questions and i'll stop picking your brains for more info. in the quest for MORE POWER would it be better to put in lower compression pistons, huge cam like the f1 diesel cam, pods or edms, 3200 or 4000rpm gov spring with 60lb springs of course, fuel pin, and piston lift pump and possibly upgrade the compressor to a 60mm, or maybe the 56mm is okay? OR.... put on twins with the same pump mods and injectors, but no cam or lower comprssion pistons. i now this may sound dumb but i don't want to go into debt over this engine i figure twins is the more expensive way to go, but i like to look at all my options.

 

ATS has pricing for o-ring or fire ring on their website. 1318.82cdn for fire ringing or 987.64 cdn for o-ringing the head. O-ring can handle 70psi fire ring will basically take more then your bottom end!

 

wow almost a thousand dollars to o-ring the head!!

 

Well, Canadian dollars...

 

so what is it in American dollars, less??

well i just looked up the exchange rate and basically candian money is like $1.3056 dollars to our $1.oo or something like that, correct me if im mistaken.

 

Stock intercoolers get leaky real fast above 50-60 PSI, don't they? The aftermarket, good for 85-100 PSI models usually have $1000+ dollar price tags on them, which gets you one heck of a water/ methanol set-up...

 

If you go with big injectors you will need more air. A hybrid ain't gonna cut it, even with help from a cam. You are better off spending money on twins than on low compression pistons and a cam.

 

i'm only seeing 400* before the IC at about 60 psi. i do definitely agree that an IC would be GOOD, i was just thinking that it wasn't absolutely necessary. KTA is hit 600 without it, sooooooo.....

and you should be able to get o-ringed for $300.

 

thats in usd

 

Sounds like your system is working good. I would have expected higher temps.

 

me too. i was pleasantly surprised.

 

I paid about $400 cnd to o-ring my head

 

hey begel1 said that a stock intercooler can only handle up to about 60psi, is that true,(no offense begle1) also with a twin turbo setup, not a crazy one for drag racing, but a normal twin setup, will i be boosting 60-80 psi? and would it just be cheaper to not intercool the twin setup and put on a water meth system? thanks
