I ended up making 550 whp on my 35r setup, with a best 1/4 mile time of 11.7 on street tires.

That's about where I want to be whp wise. How much boost did it take you to get there 30? What did you have fuel system wise, as well as intake manifold and turbo manifold?

What were your 60fts? Spinning bad with the street tires? I guess the lack of torque really kills these cars. 550whp in something like a foxboy Mustang is high 9 second capable.

Haha, 9's on our cars are not that easy, at least not for me. Hell, even with 300 more hp then that, it is still hard for me.

For 550, it took 35 psi on a custom intake manifold, 272 hks cams, 2.2 ltr and 800cc injectors, dual fed fuel rail and a high pressure walbro, with injector duty near 100% on 110 race gas. Completely maxed out fuel system.

My track times were from a result of 1.8 60 ft on 205/40/17 street tires on a 3300+ lb car.

Did you still have stock fuel lines on it? How hard were you launching the car? Dumping it or just rolling into the throttle?

were you ever able to solve your ignition breakup issues? If not I know of an inexpensive solution :)

No. Still plagued above 40 psi. There are a few COPs with built in ignitors I have been looking into. A friend of mine is converting his evo to use yaris coils, and he brought one to work for me to test out, fitment wise. What solution did you have?

Well, if you look at his mods he lists some GM LQ9 coil packs....

I didnt want to sound like an idiot up front tbh...

I just wanted to see first what he was considering to be his problem. Which I would assume is because those coil packs cant light off his fuel under higher rpm.

Since its out in the open... I figured I would make a suggestion to switch over to the LQ9 packs because of their higher amperage rating and longer dwell capacities. They top out at about 5.5ms of dwell, which is more than twice the dwell of most COPs that are available.

Trevor, are your COPs running through some sort of CDI controller? If so which one?

11.70's on street tires is definitely pretty quick for an all trac. I was just wondering how much he thinks there was left in it with good tires. I'm just wondering if maybe I should go bigger than the GT3582R I have sitting here.. Hmm..

^How much power have you handled before?

You'll find that 550awhp is still quite a bit o power to the ground.

You can always go bigger. I would suggest just sticking with the GT35 for now.

I have been in the 6's @ 200 mph in the 1/4 mile so handling the power isn't an issue lol. I am actually a full time drag racer (hence my screen name), it's what I have done for a living for the past 9 years or so now. The all trac will be my first 4 cylinder build but I have always had a love for the all trac since I was 16 and just finally bought one this past year. Just looking to restore it like yours but just want it to have enough power to be a fun car around the back roads.

Long as you have the cash and a spare car lol 500awhp and reliability don't go well.
I could only dream of that much hp
