With 10:1 comp you'll most likely need more octane then 93.
If your making 450flywheel, 10lbs should get you there. The TFS 2 is not the best turbo cam, if you go custom you can bleed some of the cyl pressure off to help with the 10:1 comp. Is this all on a stock block? If so your on borrowed time.
If you are talking a stock block, forget the boost.
Save yourself a ton of money and just have your heads cnc ported by TEA, go custom cam, and sell off your intake for a edelbrock vic jr, get a 75mm TB, 30lb injectors and you should be in the mid low 400's, for a tenth of the price the turbo is going to cost you.
No, not on a stock block. Its aftermarket with a main girddle. Tech says good for 650 fly hp. Main goal is to hit mid to high tens with as much of the parts I have already. And I want the power all the time. I do have a nitrous kit (125hp shot) that is going to push me to mid 11's. I should have around 380 ish to the fly as it stands and 125 shot should get me 11's easy with 3.73's. But having the power all the time just sounds much better.
PS I have a 80 mm maf, a 75 mm tb and 30# injectors already

"not a stock block" is a little vague for an answer.
Since you suggest it has a girdle, it probably is a stock block nobody puts a girdle on an aftermarket block.
What's the block brand and model? Not to be confused with the company who put it together, or the engine internals.
And for the record, nobody talks flywheel hp, it's all rearwheel, because once an engine is installed the only method of measurement is to the wheels.
Is this a dss shortblock or something? The main girdle won't do much but increase the chances of saving an expensive rotating assembly when the block let's loose.
With the 10:1 I would just run a bigger wet shot on a intake spacer kit or something.
