I have all supporting mods, built engine, fuel system etc.
My goal is 900rwhp, so what size turbos.
I was going to go twin 76, but I don't want them to take forever to spool up.
Also, I do need to upgrade the size of my injectors, what size are you guys running?
Take your sarcasm somewhere else. I know it has been done, so your negativity is not welcome here.
Increasing the size of the turbos does not increase the octane level of the fuel. Sarcasm should have been expected. The tune is what will make 900whp. If the 57 or 61mms flow enough for 1000hp why go bigger?
I can't speak to 900hp setups, but my car with a SINGLE 62mm pull like crazy and spools very quick. I would think TWIN 62mm's would be an insane amount of hp, but I wonder how quick it would spool. I am pretty sure even a single 76mm would be a little slow to spool, and twins would surely be a complete dog in low to mid-upper rpm range. But again, I am on another planet than 900hp setups. I would call Hellion (who was very helpful to me) and get there expert opinion.

I don't want to run race gas, I want to make 900rwhp on PUMP gas.
Twin 66?
it is possible to make big power on low octane however it isn't very safe. most pump gas's aren't very consistent and when your pushing the envelope for power you want a very consistent fuel.

you are wrong.
i make 700rwhp on 10psi with a big turbo. someone with a very small turbo could make 700rwhp as well but they would be running it at its limit, and iat's would be VERY dangerous, this could not be done on pump gas. you can make more power, on less octane, with a bigger turbo, because it isn't producing anywhere close to the heat a small turbo produces.

i have a friend with twin 61's, his car spools nicely.
when people talk of lag im not really sure what they mean, cruising down the freeway in overdrive and punching it, sure there's lag, but then hell even na and in overdrive on the freeway the thing isn't going to be really all that responsive.
response is just a downshift away, add brake boost in the mix and lag what?
who doesnt downshift when racing anyway?
and with a proper two step there is no lag down low off the line niether, so really, lag is a thing of the past imo.
