Re: Preparing a 1988 F150 for 600 ft-lbs of torque

I'm running 18psi on my 4.9 with a ported head. I have the m5od in mine with a ceramic clutch. I'm over the 700 tq range and my tranny is holding up fine with the only mod being switching to 5-20 motor oil instead of atf

Send some pics of the turbo and let me know what the diameter of the compressor housing and I will see what I come up with. Also I will see if I can locate a flange for it as well

Re: 300 efi turbo header

I know its inconvenient but if you want to send your turbo and wastegate to me I would be willing to build the setup for you on my motor and ship it back to you. I just want to see more turbo 300's on the road.

I'm considering tooling up to make up pipes for the efi 300's out there. I plan on making them for a t4 flange with external wastegate. If your interested.

Re: Centrifugal Supercharger vs Turbocharger Advice

Know my setup is different but if you want power. A turbo setup is the way to go. My 300 makes 18psi by 3k rpm and pulls like a freight train. I have a gt35 on my engine and some head work with forged pistons. I admit I'm not that familiar with the 200 capabilities but I think a t3t4 turbo would sui...

Re: Anyone here successfully running an aftermarket EFI System, Megasquirt, Holley Hp, Sniper, Atomic, FITech?

My ms2 has been running for over a year on my project. As far as how well its working..... I had to have a custom clutch made from ram clutches to support all the torque I'm making. The ceramic clutch I had let go after 12psi of boost. It made it 3 days at 18psi. It only took one day to get everythi...

Re: Turbo 4.9 f150

The factory ecu is maxed out due to being tuned for such a small injector. I have already tried to work around it. You can get a used megasquirt cheap if you can't get a new one.

You should have no problems with that. I would recommend at least a 30# injector though. Go heavy on the fuel system. You will be glad you did

I have the mdo5-r2 as well. I've heard its weak but mine is going strong. The only thing I've done to it is change from atf to a 5-20 motor oil. My megasquirt hookup only took 3hrs so its an easy swap over

The megasquirt is pretty easy if you understand engine basics. Just don't get greedy with the timing and you should be safe. And as a daily driver...... Before I was making gobbs of power it was great. My problem is I'm using a 5sp so a clutch that can handle all the tq is kinda touchy in traffic. W...

Based on displacement you would need to rev way past what a stock cam could do. But if you could come close to 6k it might work

I'm curios as to what people are getting for power out of their built 300's. I'm hoping to hit about 500hp and 850+ tq out of my boosted motor this year.

Re: 250ci turbo questions

I know im new to this forum but I have been building turbo cars for some time now and my take on this is. If your running good internal and have a well thought out turbo kit 10's are no problem. You might have to make some of your parts but its worth all the time in the end.
