s400 big hp?
s400 big hp? I am working on building a boosted 5.3 for a pulling truck. I happen to have a mpt70, godspeed 72mm, and an s400 turbo all sitting on the shelf waiting to be used on something. I need to get a minimum of 900hp+ to really make it worth my time. This will be my first BIG boost build so looking for some advice. Will an s400 support that kind of hp? Want to stay cheap, any cheap good performing turbos out there? Prefer single but would go twins if necessary. How big of injectors will I need? Not afraid of RPM's. Was planning on stock bottom, stock heads with some work done. Any recommendations on other mods? Any users or sponsors that would be good to talk to for advice on this? Thanks in advance for any help you can provide.
Lots of S400's out there. The diesel guys run typically S475's or S480's.... but usually in a twin application with a smaller turbo. I think I've seen some S475-s480's in the 600+ HP range but thats on a diesel, not sure what you are looking at on a gas motor.

10 LS Engine Myths That Refuse to Die
Verdad Gallardo We were making about 800hp on or diesel tractor with this s400. Don't know for sure which model it is though. Our diesel supplier just told us to put it on and we would like it. It was running all over gt42's
since the exhaust is a 5 inch out do I need to reduce my downpipe to like a 3 inch for backpressure or do you think it matters? On our diesel engine our diesel supplier had us reduce the exhaust down to 4 inch. Also is a air/water intercooler going to be worth the added cost and weight vs just an air/air cooler? Any other mods or tricks I might want to know to reach my hp goals?
Thanks for the help identifying my turbo. I have two of them, will a 5.3 spool these with twins? Or would I be better off with just one? As long as I can reach 900-1000hp with one I'd rather just run the one and have a backup
That turbo is rated at 1050hp if I remember correctly. One should reach your goals if you want 900 at the flywheel. Run the biggest down pipe you can fit you don't want back pressure. Not sure on the inter cooler, how far do you pull, how long does the pull last and what speed do you get up to? If your not pulling for very long or very fast an air to air probably won't do much for you. What type of fuel are you going to run? Can you run meth injection or E85?
I decided to go with a S480 with the 92mm turbine on my build and I am doing a air to water intercooler. Since it is a street car too, I chose to do a heat exchanger (although not a huge one) and a water tank as well.
As for the downpipe, I went down to 4" mainly due to packaging constraints. If you can keep 5" do so!
