Fuel Mods to Support 800whp TT Setup w/ 93oct (NOT e85)?

[SolarFlare]

Probably easier to just ask the dyno operator to put the temp stack for the dyno into a mount of hot coal.

The problem with your statement is that hellion has already surpassed 800 and 900whp with 93 oct.

If they hadn't then I would agree with you.

Give it a try and let us know. I genuinely hope it’s possible. Many shops made over 850whp on 93 too but that doesn’t translate to normal users. It’s more of a look at what we can do

On a dyno.

Put it in the real world with temperature swings and changing driving conditions and it will pop.

People just don’t get how fragile this engines are to detonation.

93 and heat just don’t go together.

Buy E85 by the 50 gallon drum it's stupid to push the car that far on 93 it's a ticking time-bomb at that horse power level. But if you like buying motors go for it

To attain that on 93/94 octane, your biggest issue is going to be heat.

Best options?

Ported heads, camshafts and a great tune.

Even with the above, I wouldn't risk it for longevity sake without a water meth kit with multiple failsafes.

I've seen articles where people dyno over 800whp on 93, but the engines aren't stock, have ported heads and airflow enhancements.

I'd love to do this, but from a cost benefit analysis, I see the venture of going for high WHP pump gas as an excessive expense of time/money in comparison to the alternative.

What I thought.

Lol... let me know how your quest goes, sharpie. Ill be watching.

While you are shooting for 800whp (not 1,000), Hellion did not do it on a stock motor (from their 1,003 rwhp on pump thread):

↑
Is the engine stock for this 1000 whp run? Any internal engine mods, other than the fuel cam?
We replaced the rods and pistons but it still has stock heads and cams (aside from the larger fuel lobe) and all VCT is still operable. We built it because we are going to go above 1000.

Compression ratio was also changed (again from their 1,003 rwhp on pump thread):

What is the compression ratio?
Hello. We rebuilt this one with 11-1.

What gen motor? I made 825 with the Hellion sleeper on a gen 3 using 93+boostane. Was 2 full cans to the tank so a little over 102 octane. I have the stock pump with JMS bap and DW95 injectors. About 12.8psi I’ve turned it up to 13.5 on 3 cans on the street but never dynoed.

The only way to get 800+whp on 93 is meth injection or alot of octane booster.

The dyno result your going by is from a manufacturer who is trying to sell products. Look at the majority of independent peoples dyno results. You wont find anyone making 1k hp on 93. Dyno numbers can easily be toyed with correction factors, temperatures, etc.

On the very best 93 with a reliable tune, you'll probably top out somewhere under 750whp.

Was that Boostane “Professional ?” It takes a little less than 1 full bottle to treat 16 gallons of 93 to 102.

ahl395 is dead on. On my 18 Whipple (not TT, I know) I was able to make right at 750@7200 on straight 93. At 7200, it pulled timing and we let out. Drained the 93 added E85 and made 887@7800. This was done with Fore triple L2 and ID1050X

I only run professional. Buy it in the 5 gallon pails. I fill the smaller cans from that. I usually run a full can per tank but for the dyno I dumped a second can in. There are some serious diminishing returns on the actual octane number once you go past a full can. You will still see results though, I can see a degree or two more of timing for each can I put in after the first but the first can is where you see the best bang for the buck.

with the Turbo an engine doesn't have to make as much crank hp to make 800 rwhp as a supercharger because there is no parasitic hp loss from turning the blower. i'd be interested to know just how much hp the whipple or edelbrock takes to make 800 rwhp. i'm guessing they rob at least 50 hp

I’ve got nothing against turbo(s). They can make huge power. However my street driven Whipple car will run 8.70 this year and that’s all I need, so I don’t care about parasitic loss
