I make 650 on 100 octance but I don't count that as pump gas cause I can't get it at every station. I guess I am like a Jr Bryan lol since I am from the same town and just a lil younger. Give me a few years and a bigger income and I'll see if I can keep up.

A 346CI Alminum LS1 should be able to make way more then 650rwhp on pump gas before it becomes risky. I've heard of 183CI Toyota supras making 600rwhp on 93 octain.

Yo MM, here is Monty's car. He sold it a while back and I believe the new owner wsa backhalving it and going racing with it.

Its not however, an LS1. But I still think you'll find it interesting.

No, I am not kidding! If you'd like, I can start naming parts! Stock LS1 engine, TEA heads, Lunati billet rods, Turbonetics 60-1's, Racegates, Spearco 282 intercooler, Etc. I own a little buisness doing auto repair and custom fabrication, so all my fabrication is free! I get some parts at cost, but for the most part, I kept an eye out for second hand new parts. It wasn't easy, nothing is!

I consider this a "cheap" setup. As far as Monty Williams motor, I had the exact same motor minus the twin turbos. Monty and I built our motors at the same place at the same time. Sold mine to a member of this board on New Years.

I decided I wanted a cheap motor with a little boost. My goals have changed with my family and I wanted a low dollar "fast" car. Unfortunatly Fastimes motorworks cannot tune the stock PCM's yet so I am stuck going elseware for tuning.

I guess with a pumpgas car, tuning is how you get there. With 347" and good heads, 750+ rwhp is attainable on pumpgas with a good tune.

AGAIN, LET'S NOT TURN THIS INTO AN ARGUMENT... JUST POST UP YOUR POWER NUMBERS AND COMBO.

You'd find more people hitting 800RWHP on pump gas if they built the motor with ~7.5-8.0:1 compression and used the compressor (Super or turbo) to flow the air required for a target power level.

Alot of folks build setups with 9.2-9.5:1 and up compression which immediately raises your octane requirement at a given boost/cylinder pressure level.

7.5:1, the right intercooler setup and fuel system 20 plus pounds of boost is possible on 94 octane

Thats a really good point you brought up. Most people have not "designed" there setup for pumpgas. Personally, I chose a super efficient 60-1 hi-fi turbo, The largest of the shelf intercooler Spearco makes, and am at 8.1:1 compression. Most people are worried about "lag" but think about it, without the turbos, is 375+ rwhp really gonna be that laggy? If you design the setup for it you can make bigger numbers.

Anyone else making big power??

I love how everyone thinks high end motors cost 5 digits to build. Id say most of the people on here dont know how to do much themselves except change oil (NOT EVERYONE)

Those of us that can actually do things ourselves, save a LOT OF $$

i agree, lets stick to figures that have actually been reality.. i am seeing too many .. it coulds or it wills or it woulds if... go do it.

5litereater did 700rwhp on 93 octane with 14psi STS kit (then he blew a head gasket).

Wouldn't that then be an example of it not working on pump gas?

I made 754rwhp, t400 trans, on slicks, with C16. My 83 lb injectors are close to maxed, so that's over 950 crank hp.

John, From what I have heard and seen, your 83's ahould be good for a LOT more power then that??? Are you running real low fuel pressure, or could your pump not be putting out enough causing your injectors to have to open 100% to accomodate? That's odd?? Isn't Mightymouse making over 900 rwhp with the same injectors?
Tell more about your combo, everyone likes to brag!

i have 96's and i run them from 3 bar base +1/1

they are closing in on 80% duty FAST.. but then again i'm below 10:1 a/f wide open

man thats alot of fuel going into your motor, bet you still get 30mph dont you

KAOS

so with a iron block is 750+ rwhp possible safely without the methinol. pump gas only?

MIGHTYMOUSE

iTrader: (59)

you mean mpg? no i certainly dont.. i get pretty shitty mileage when i'm WOT

but i still get about 200 to the tank city driving during the week.


or do you mean 30mph in the second 1/8th mile.. if so then yes i actually get a little more than that.

eviltwins

Sure you can. Almost every single person at the pump gas drags this year is on an Iron block. One of the guys last year made 940 RWHP on 93 octane with a small 331" Ford. One of the guys running this year works at Murillo's shop and he's gone 8's @ 165 MPH in a 3600 pound car on pump gas, with an iron block, and it's street driven regularly. There are 2 5.4 DOHC ford motors that I know of that have bested 1000 RWHP on pump gas, and they're both obviously iron block motors, and one of them is street driven with frightening regularity. If we're talking about with methanol, Wolverine on here made 950 RWHP on 93 + meth, with a 331" motor and they only turned it to 5500 RPM's before the dyno would shut off because of too much torque. A full 7000+ RPM pull and that's 1K RWHP easily. Danimals car would break 1000 RWHP with ease on pump gas + methanol as it sits, or on straight pump gas with a bit lower compression.

My car is blown, with a T400. I use more power to turn the blower and you can't compare a T400 with an M6 car. I'd expect to be over 825rwhp with an M6.

How much power is that car making?

Bryan Wilkinson

Let me clarify, None of the cars listed above running iron blocks, have 10:1 compression and make that power.

The thread was not about who had the fastest car on pump gas. The thread says who has the most power on pump gas. No Meth, No Alky, No Water, No C16, just plain old 93 Octane.
