HP guessing game

THASTIG · 05-09-2021, 05:54 PM

Hey all I just finished everything on the car and ready to take it to the dyno on Tuesday. I do this with my crew at work, lets get some guesses on what the car will put down... Be nice to me 😂😂😂😂
Previous power was 457whp 449wtq on 91 and 487whp 479wtq on E85. This is all at 4500', DA varies up here per hour so good luck with that. Mods were 103tb, MSD IM, K&N intake, TSP 1 7/8" long tubes and E85. This is a 17 1LE M6
On top of all that i just added a D1SC stage 2 with race bypass, LT4 high side fuel system and AEM water/meth V3 system.
Pulley size was dropped too I now have a 8 rib 3.7" griptec on the stock procharger lower pulley, at this altitude its should be 10-12psi but thats also just a guess.
Im thinking depending on the day I should see 630-650whp. Not too concerned with the actual number just want to run 10s. Let me know what yall think.

Nice one player.. You're at high altitude too right? What are you at right now hp wise? What's your setup?

Joshinator99 · 05-09-2021, 07:19 PM

I don’t see anything helping the low side fueling...? LT4 in tank with JMS is entry level into blower world IMO.

Its a 1LE so it has a LT4 in tank pump already

I'd say 620. What I'd really like to see is what your low side is going to do and see if it starts falling off.

It should be fine, like I said I have a 1LE which has the LT4 in tank pump and I have upgraded to the LT4 HPFP and injectors, I also got the LT4 fuel lines. Im not going to run E85 since I have the meth injection if thats what you guys are thinking

Yes, I’m at 4500’. Setup in signature. I was 608 before the latest mods. My tuner estimated 700 or so.

Upgraded internals and increased ring gaps?

LT1ornothing · 05-11-2021, 11:26 AM

91 oct, meth, 12 lbs boost, stock internals and attitude. Sounds like a recipe for a ticking time bomb. Another forum member recently popped his LT1 on a P1SC @ 11 lbs, similar setup too, pump gas + meth, he claimed his set up lasted 1 year, about 20,000 miles boosted. Your set up has more fuel upgrades, but less octane.

By no means am I saying this will be your fate. Just know you are rolling the dice. Many reputable tuners recommend running an ethanol blend like E60 for your type of set up. I believe you will be very meth dependent.

As far as guessing power, 660 rwhp if it holds.

I was thinking the same thing. By no means would I ever want meth in my setup. Either straight DI or Di mixed with Port would be my only ways of going for fueling. I don't want to jinx you OP but this setup would constantly have me worried so I hope it works out for you.

Can anyone else verify this is true? I wasn't aware the 1LE had an LT4 low side pump stock..

As for guessing, I'd say around 600rwhp

I just added a LS pump to mine, so...no, unless they forgot it
