well after working the bugs out of the built engine and the turbo intake pipes which turns out have been holding the car back for YEARS now.
Than i did the M6 to 4L80 swap, was the best thing i ever did to the car. it ran 9.96@140mph with a lame 1.68 on 13psi of boost. This al so had the injectors pushing 96% at 6500rpm. The car is a easy 3800lbs. i was only on a 2bar map, so here is the plan i sent out the 60lb/hr injectors to be upgraded to 80s. put a 3bar in and the meth back on the car. going to try to get it to the dyno shop in a few weeks here.

i want to run some 9.0 index stuff and maybe some street class. 8.50 cert. cage is on the list for this winter.

so for this next stage in the cars life im thinking of taking it up to 18psi on pump and meth and seen how it goes from there if thats looks good might shoot for 20psi!!!

so this is the plan anything you guys can think of that might help me along would be great.

Thanks guys

ps transbrake coming after this is done

18-20 psi and pump fuel going down the track? Blown motor. I would just use e85 or race fuel at that point.

Yeah and I wouldn't run 20 psi on it.

GueSS Who

We run at 20psi on a 427 with the APS kit and it runs 5.34@131 with a 1.24 60ft on 275 radials. We have the stock turbos on the car. I think you could probably go quicker then your 8.5 if you really wanted to.

i dont think im the frist guy to do it in here. im pretty sure mightmouse is 20+ on his car but i could be wrong

FWIW, I run 18-20 psi on my APS car with pump and meth

Good luck to you man. Its should be a beast

02 how much power do you make with your car at that level of boost? And with what trans?

tomz28

iTrader: (20)

GueSS who. What's up buddy your car is a missile for sure. But you got a lot more CID than me(364ci) lol. I think 9.0 index is good for me. I also need to lose some pounds on the car

You'll be fine man! With the larger injectors you wont be tapping out the fuel setup. What size nozzles for the meth...forgot to ask you and twins correct?

tomz28

iTrader: (20)

yes i will use both for this. but now i need to fine the space to put them in. you know how same that space is. i might just drill and tap holes in the innercooler it self

I'm pretty sure that he lost a motor due to trying to be a pump gas/meth hero, and vowed to run race fuel above 16 psi or so. I am for using meth to be able to run a few lbs higher or run a extra few degress of timing but its just smart to understand your risking thousands and thousands and thousands of dollars to save $5-$10 a gallon? Esp at the racetrack where there is fuel readily available.

i do understand the concern and id like to run just race gas at the track. but some events might not let me use race gas in the furture(street classes). we need mightymouse to cime in on this to see what the godfather has to say LOL

i want to do hotrods drag week and run the street class i wounder if they will let me use race gas?

116 is a great insurance policy. Some get by without it....some don't. One little hiccup on that tiny meth elec motor = boom at 20psi.

I would not put 80's in your car....you'll be taking them out shortly with the power potential that it has...and your weight.

120's rated at 3bar would be the minimum...if the pumps get weak...the duty increases for safety if you have wideband feedback. You don't have to now....but you will later

i cant argue with that. you are right no matter how well the meth is set up it will only take a fraction of a second to END my motor. so with this been said could i do a 50/50 mix of pump and race gas? or is that still not ok for waht im doing?

i just want to drive to the track do some low 9 passes and drive home how can we make this happen. this is still a street car guys remember that


my 60s only had 65psi on them at full boost. im going to run the same base fuel pressure with the 80s or should i trun it up some to safe?

some weight will be coming out before this summer as well

At 20psi I would want a minimum of 110 oct. So it depends on what you are mixing.

Which computer are you usinf 99+ stock or aftermarket?

What fuel system are you running.

It won't take 20psi to run low nines if that is all you want...but you will always want to go faster...that's the reason for 120's...pay me now or pay me later....lol...

Here's my 4037lb street car with AC working...my goal was only 10.8's and drive it on the street...it never ends....

sweet vid

twin walbro 340s with -6an to a Y-block into -8an. -8 to the back of PS fuel rail. cross over in the front to the DS rail with -8an. with -6an at the back of the rail to the FPR and using the old stock feed line as a return.

the 20psi is more to get a base tune for it and to see what it does on the dyno lol. i know i dont have to push 20psi to run low 9s. im going to start small and work on dailing in the car so i have a great 60 foot and only after i do that will i start working on turning up the boost.

im runnig stock 2000 cumputer

so what is a good plan for fuel? just drain the pump gas put in race gas and drive it to the track. that kind of sucks or drive it there low on fuel and fill up at the track with race gas?

At 18psi I make mid 700's to the tire through my M6 trans with a 347cid with bone stock LS2 intake and untouched 317 heads. That's through original sized APS 20g knockoff turbos with pump gas + meth.
