300whp S70 T5 Manual

Probably cost over $4K to make that 300whp lol.

Jared you should just make 300 whp already so you can make posts based off of experience like Rob's...

Until then, your mocking people who do things right and actually get results doesn't really amount to much ;)

To the original poster, it's been well covered here (and there is at least one similar thread here on the first page of the forum now where I've weighed in more heavily (My Planned Upgrades or something). But basically, a 19T with good exhaust, larger injectors (blue 395cc would probably be most preferable), and good tuning will get you what you want. Upgraded intercooler makes it much easier to do so... But not absolutely necessary for 300whp. I would fully recommend it if funds for it are available.

lol are you serious? You have one of the ghettoest and most powerful cars in FL, doubt it cost you close to 4K. You did it closer to right..

what are the overrated dynos ? what are the ones that are underrated???? i guess . . . .

Mostly cooling issues.

19T setups with larger IC will hit 285-290 without to much effort but stock IC setups will suffer.

On the street this is a different matter. Often the amount of boost reach on the street vs dyno says enough.

When all was said and done, probably 2500+ or so for my hybrid turbo setup, and that's doing everything myself including all the exhaust work and all fabrication. A 19T setup when finished will probably have similar costs unless you are buying someone else's setup used. Neither of those costs factor in intercooler upgrade.

When I put the wagon together, I'll probably have a slightly higher cost, but I will hopefully be putting in a different intercooler and fixing a couple of issues with the sedan's current setup...

Well I am basing the costs off of doing the majority if not all the things yourself. So you're right there. Likely get a superior turbo at a better price and an intercooler setup if done yourself would cost around 500 with a good core.

If I read another "how do i get 300whp" thread, i'm going to puke

:rolleyes: Why don't just post do a search?For what?It's a good thing to get new advice from people that have acheived what I trying to acheive!

Thanks for all the positive responses for the people that did so.For now I think I'm going to try to get the most out of the stock turbo with a custom rica tune water meth injection and full 3 inch exhaust.To bad the exhaust housings are so small on the stock turbo's.

I'm sure everytime someone post "how to make horsepower" thread something new comes out of it.I can promise you I'll be thinking up of something ;)

John, port the housing outlet on the turbo. Maybe port the manifold side too. Maybe even look into a super 60 wheel. I know thats what I'm doing now, if nothing else porting the manifold side a bit. You really aren't going to want something pushing huge CFM on stock rods. When you start getting into the higher CFM ranges of bigger turbos our rods bend like toothpicks under a fat lady :-\ (especially untuned)

Actually thats what I was thinking! Boost pressure is directly related to a engines inability to flow.Of course if everything stays the same,like cfm rpm,etc..prob alot of the reason rods get bent is from detonation but I'm sure alot of cases is from overboosting and the backpressure from the small turbine and restrictive exhaust cause a sort of hydraulic lock sorta say of boost and piston can't squish what can't get out..I think some porting is going to def. help..I would like to see what kinda results from people that switch to the s60r exhaust manifold and go with a turbo with a larger turbine :unsure:

posted at the same time..lol

Actually, Joe... I'd be willing to bet that a turbo with a larger turbine helping produce more efficient boost and potentially a bit more lag will help our rods out with higher hp goals.

You are right on Joe.Take for instance the .41 A/R housing (stock volvo). Changing turbine A/R has many effects. By going to a larger turbine A/R, the turbo comes up on boost at a higher engine speed, the flow capacity of the turbine is increased and less flow is wastegated, there is less engine backpressure, and engine volumetric efficiency is increased resulting in more overall power. The .41 A/R is able to create the pressure differential at a much lower engine rpm, giving the compressor ability to make its maximum rpm speed sooner, why the 15G and all others spool very quickly. As the engine rpm climbs, the pressure differential is lowered due to the physical volume of the housing size becoming a restriction on the post turbine side - volvo turbine housing suck !. As the housing size is increased, it take greater engine rpm speed (greater exhaust energy) to spool up the turbine, but the pressure differential is less effected by the physical volume of the housing. If you are after maximum midrange gains smaller housings are essentially (15G,16T,18T), if top end gains are essential larger housing are essential(16G,20G,3071R, 28R).
