I plan on adding an edge comp drag box also adding a little bigger sticks and having my hx 35 made in to a hybred would that get me close to the 400 hp range? also will that turbo handle that hp ? is that a good choice for some one that tows alot . thanks for your oppions.

 

IMO, it will be way to hot to tow with. Forget the turbo hybred and get a bigger one.

 

A hybrid Holset is barely capable of supporting 400.

Go bigger on the hot side, and accept the lag that is part of life with a more capable turbo.

jh

 

I think you would be alright. There seems to be no perfect setup for 400 HP, without sacrificing spool up, egt's, etc. I am thinking of doing a hybrid too. It is cheaper, & at least you do know what it can do. It will run cooler, because it has more air flowing.I wanted an HTT, but it seems that you have to give up too much, whichever way you go with one of them, at least according to a long running thread on here right now. Good luck.

 

400hp should be doable with a Hybrid. I did 440 with Hx-35 on Drag comp and Mach2.5's in the old 5spd truck and towed with managable EGTs with just the sticks

 

I will turn the comp way down when I tow witch should drop 80 hp so then the turbo should handle low 300s hp dont you guys think?

 

I did 390 with my setup.

 

are you guys serious? with mach 6's and a smarty i was getting to hot (380 hp approx) with a sps 62/14 while towing. And thats alot more turbo than a hybrid.

IMHO, yeah its possible but not good for #6 piston (or the rest of them for that matter)

 

Bob Wagner made 401 with a 35/40, smarty, amd mach 4 (150 hp) injectors.

 

Let's also look at what you're towing. You can get by towing small stuff and not worry very much because you're not working it that hard. But as you step up to large loads, you're having to watch the pyro the whole time to make sure you don't snap the needle off.

It's also not so much about what peak horsepower your turbo will support when running the dyno, it's about how well it works when you're in your towing range. You can hop on the dyno and run a quick peak up to some HP number and it'll work fine with the stock turbo because you ran for a few seconds. Now you turn around and put the engine under load and keep it at that higher HP number and things are melting because you can't keep it cool.

I could make dyno runs with my Smarty and TST both maxed out on the stock turbo and it wouldn't run too hot that I worried. But when I hooked up a trailer and ran with the TST on 2 or 3 and the Smarty on 7, I could max the EGT gauge if I wasn't careful.

 

Yea i wouldnt suggest towing very heavy at all with that setup.

 

What are the Stage 5 Jammers rated at? Just trying to compare your setup and mine. 390 seems to be low, unless I'm thinking those injectors are larger than they are.

 

There supposed to be 150 or maybe 155 i thought it was kind of low myself but not sure? I think my stock turbo is what is killing me well besides my clutch.

 

We just recently dynoed a customers truck 99 auto with Drag Comp,AFE,4" Exhaust and Jammer 4's did 402hp

 

Putting down #'s on a dyno, and towing with it is two totally different things.
