turbo questions

[GranSportSedan]

I am in the procees of going turbo charged on my 300 engine. I have figured out i cant flip the exhaust manifolds because the drivers side will hit the cross member, looks like the sanderson headers would work if flipped but when i read the specs on the website it staed the primary tubes are 1 1/2 inch and are only good for aprox 300-350 hp. obviously they are talking naturally aspirated and i'm wondering if they will be capable of handling more than that in a turbocharged application


NOTES:

This header offers 1½" primary tubes, which is good for about 350HP on a casually used 350 cubic inch or smaller engine application.
The Patented Leak-Free Design that Sanderson Headers offer you is the only leak-free flange design on the market ... Do Not Attempt To Use Flange Gaskets! The raised flange on the Sanderson Headers will buckle the gasket during tightening and actually cause a leak!
Sanderson Headers are NOT emissions legal on pollution-controlled motor vehicles. It is the purchaser's responsibility to verify local regulations for compliance.
Wrapping your Sanderson Headers with ANY thermal tape voids your header warranty. The best thermal protection for your headers is our Aluminized Ceramic Coating that is available for every Sanderson Header.

Talk to Mark Burton. He's been working turbo set-ups for a while now and could probably make you a custom set-up.

thanks for the advice, i really dont want log style manifolds and i want to build the setup myself. i'm a detail freak and if I build it and it's not to my liking then i only have myself to criticize

yes the manifolds will support alot more than the 300-350, just for an example, my motor has stock manifolds and so do alot of people that have turbo ls motors...just the stock manifolds will support 1000rwhp when boosted, now if NA youd be hard pressed to hit 500

Good to know.. I'm not shooting for 1000 hp but i do want a little kick from my 300 :Brow:

Usually with turbo headers guys like to keep the primaries the same I.D. as the exhaust ports so that the exhaust gasses don't loose velocity on their way to the turbo(s), then the downpipe(s) are as large as they can possibly be so there is the least amount of back pressure possible.

Thanks for the heads up on the manifolds BTY

you could do like the sts turbos and mount it toward where the collectors are or rear of car
