Most power with only a LPFP upgrade? ST or TT?

wren57 · 06-29-2016, 11:10 PM

I don't want to add fueling beyond an upgraded LPFP. Given that constraint, is there any reason to go to a ST or anything bigger than a rr600 or pure s2?

major HP gains with a single turbo. Think 750+
, also expect major lag. Twins are supposed to provide stock like quick spool.

Major lag? Full boost is at 3500 rpms for most single turbo setups. That is no way a "major lag".

But that doesn't address whether or not more fueling than a LPFP is required to hit those levels.

A single is pointless if you don't plan on adding more fuel. They are way more efficient but if you don't add pi or tbi then it's a bit of a waste.

That's what I figured, just thought I'd ask. Decisions decisions...

Hey wren, I'll be selling my Hexon rr550's (wedge made 600+whp on these) in the next few weeks if you're interested. I'm putting down around 550whp on an e30 custom flash.

Not really,
93 octane and fuel it stage 2 without port or meth got me 548whp
93 octane and fuel it stage 2 without port or with meth got me over 630whp

haven't ran e85 and meth yet on the dyno but i would assume ill be over 730whp easily without port.

You'll need pi/tbi to hit those numbers. stock hpfp won't do.

in that case...that solves OPs problem. unless he doesn't want to run meth.

you arent going to hit over 700 on e85 without PI or at the very least TBI.

Id be interested to see what your HPFP is looking like as is on the 93 as well. More air = more fuel and the HPFP just cant keep up with most peoples demands.

I am running 30 psi now which with this turbo is good for well over 700+whp

93 mix with e85 and methanol.

wren57 · 06-30-2016, 02:51 PM

Meth is considered fuel IMO. I hate the concept of Meth. Just my preference.

1BADM3 · 06-30-2016, 02:55 PM

You going to have to add fuel for twins, single or nitrous if you want over 700whp that is common sense

You seem to have missed the point of the thread.

if you are running 30psi, youd be at or over 700 with proper fueling... Just adding e85 isnt going to magically get you to 700+, you need to adjust fueling to make it. And since you need more fuel when using e85, you will need to add fuel, which is probably close to maxed out for you if you are running 30psi.

post a log, lets see your HPFP readings.

Also, looking through your build log, you ever been on a dyno? based on what ive seen, you havent gotten any real numbers, just what you think it should be doing...

Well yes, you do have to set that up as well. So the simple answer to you original would be- No.

That is without port injection.

So your suppose to post everything online? Everytime i go to the dyno or change my car i have to post on the forum? Lol

I know what my car did on the dyno at 26 psi, now that i am running 30+ psi the car will easily make 700+whp on e85 and meth.

So you're a keyboard racer. This all makes more sense now.

You're the one that came in here abrasive and off topic. Nobody asked about 700whp, the question was what power is possible with only a LPFP upgrade.

Seems to be about 550whp is the limit. At that level there's no benefit of a single over twins except ease of replacement.

NA55 · 06-30-2016, 08:24 PM

I made just over 550 with e40 on a stage 2 LPFP..
