Has anyone made over 700whp with the gtx35r?

Yes, but, you basically need a big intake and no exhaust and E85 and a friendly dyno.

A time attack car I used to work on made 747 at church and then 727 at ums, both dynapacks. Given the difference in temp and elevation I would say they both ready pretty similarly despite what you might read elsewhere on the internet.

This was a gen 1 gtx3582. Hitting 700 with a gen 2 would maybe be a little more realistic.

Which one, specifically? GTX3576R? GTX3584RS? There are quite a few different setups at the 35 frame level. I'm also assuming you're talking about a single V-Band feed with the largest A/R available, right?

^ This.

There is a good ~300whp difference from the small 3576 to the new 3584.

From my personal experience a 3576 is going to get you in the 550-600whp range on E85 and ~450 on pump. For a regularly driven street car, this is as big as I'd go.

The 3582 we've made 760whp and 706whp. This was on Prime Motoring's Mustang dyno. It was also on E85 and a very custom low mount manifold, exhaust, etc...

Have not done anything with the 3584, or any Gen II variants, but expect ~10% more whp with the Gen II.

I have the gtx3582. I made 510 whp on pump gas at iag. Which was a conservative daily tune. I just got e85 around where I lived and would like to make 700-750 whp was just wondering if I could do it with the setup I have.

As your numbers show, a Dynojet reads on the higher side, so you should have no problem hitting those numbers on E85. Assuming your mods will support it.

Fueling capabilities will need to be able to handle +40% more flow. This is where running E85 (reliably) can get really expensive. E85 upgraded lines are REALLY expensive, you'll likely need a second fuel pump, bigger injectors, etc.. It just adds up.

I agree with KillerB, those numbers should be attainable with E85 and supporting mods.

E85 burns right around 30% more fuel per combustion event, are you referencing 40%+ for a safety margin?

BTW I made 629whp dyno jet with a HTA86 and E85, using stock fuel line to the engine bay back in 2009. I was using aeromotive fuel rails, 2200cc injectors with a bosch 044 setup in the trunk (so your right on point $$ wise ), but what I am trying to get at is the stock hard fuel line up to the bay is actually good for some pretty decent flow.

Of course a little bit bigger fuel line would be better but on a budget stock lines can do some work.

Bigger isn't the reason. It's more like what they look like after continuous E85 use

Alcohol based fuels (Ethanol and Methanol) corrode generic steel, which is what the stock lines are made of. To run E85 you need an entirely new fuel system from the pump to the injectors if you don't already have E85 compatible injectors and fuel pump. And as KB has already stated...that gets expensive quick.

Methanol guys still purge their fuel system every off season and leave the lines open so the remaining methanol can evaporate and cause as little damage as possible while the car isn't in use.

I have run E85 through those subaru stock hardlines for years (started running E85 fulltime in 2008) without any corrosion problems. Have you seen an example of someone who has had a problem with the subaru stock steel line corroding from running E85, with some photos?

Remember those 100% methanol guys are nuts. 100% Methanol is quite a bit more corrosive than E85 too. I would want to limit the damage as much as possible if I were them guys. I store my car full of E85 all winter long in MN, fuel lines still on tight, not a single problem.

I didn't document anything, but after some use, I didn't trust the OEM lines. Anything flexible became petrified with excessive surface cracking. Seeing as how my wife/kids are sometimes in the car with me, some research seemed to point out that running proper E85 rated lines was the way to go. Also the power level we were targeting might be OK with the OEM lines, but I really wanted to be sure the turbo was the only limiting factor.

I've read of other guys running years too. I really don't know what to think of that. Are the line ratings changing per year/gen, or are tome suppliers providing better lines than others? Anyone's guess.

Remember we are not talking about the rubber lines, we are talking about the steel fuel line that leads from the fuel tank to the engine bay. I have not seen one single report of a corrosion problem running the stock steel fuel line.

All my stock soft/rubber fuel line was replaced before I started running E85, with E85 safe fuel injection hose (goodyear from orielly auto iirc ), so I dont have any input on the stock rubber lines E85 un-compatability. Since we ventured into this territory I will say this; NOBODY running E85 should keep any of the stock rubber fuel line, thats just taking a serious gamble. Especially with so many people running higher fuel pressures to compensate for small injectors...

Of course at a certian power level it is just a given that the steel line will need to be replaced, who knows maybe 700whp is that limit, I dont have any personal experience past 629whp dynojet with the stock hardline. But dont get me wrong I do 100% agree that running a bit larger line for high whp applications would be ideal, its just not always needed. Now for example in your situation where you arent messing around, you have a power goal to hit and dont want any limiting factors getting in the way, thats a situation where running a larger line is a must. Its a racecar

the hard lines that run through the chassis inside the car are fine for E85. it is all rubber stuff in the engine bay that needs replacing.

Very interesting posts here....good stuff....real good stuff here guys...thanks.

I will be reworking my fueling system. Originally I wasn't planning on a rotated setup, but I changed my mind. Currently I have a DW65C in the tank with ID100's, pretty basic. I guess I am technically set up for e85, but I don't have a map for it and was thinking about the entire fuel line issue. I'll be doing some other things too since I'll be in that area anyway.

I've been visited by the parts fairy- here is what was left while I was asleep.

40 feet of Fragola 6000 series PTFE hose to run from the primary tank, to the surge tank, past the firewall, and all the way until the injectors. Ran next to the stock line under the car whenever possible

Radium surge tank holding 2 450's the new ones. Both to be hard wired to the battery 20-0138-02 MPFST, Dual Walbro F90000274 E85, Pumps Included

a bunch of Fragola 6000 series red and blue aluminium hose ends.

a hobbs switch to turn the second 450 on at about 10psi perhaps

the parts fairy took back the ID1700's that were left during the last visit and replaced them with ID2000's - the note that was left said something about even V2.0 1700's having some trouble - i don't like to argue with the parts fairy.

Your stock intake mani won't hold you back much at 600whp

I made 540whp on a lower reading mustang with e85 and a gtx3576 .82, id1700's, single wb 450 pump. So I'm sure you will make 600

Yes! It that 3582 a Gen I? I made more with our low mount setup on a Gen I, but we're in the same ballpark. Definitely curious how the 3584 compares. I've been considering it... if I don't sell KBM1. From the info I'm told, it should make a good bit more power.
