Its a First Gen


Ok here is what I have in mind. 800hp pump gas 900 race gas.

Twin Master power T70s( maybe PrecisionGT4088-hybrid 67mm) turbos
2- Tial 38mm waste gates( already have)
BBK shorties turned around backwards( already have)
3in. Downpipes
2.5" from turbos to I/C and 4in. to TB( already have the aluminum 2.5 piping, silicone hose and t-bolt clamps)


Questions...
What size I/C are you guys running??
What fuel systems??
Anyone using stock computer??
I have a Stock stroke Scat crank and eagle H-beams should I do a .030 stock block(only block I have) or do a 408?? Will it be worth stroking it??

I run a Powerstroke IC, sumped tank with twin Walbro external 255's, upgraded lines, 60's HPX Mass air in blow through, mass air conversion. I run a stock T4M0 (94-95 Mustang GT) PCM with a tune. I would not stroke it.

Blue Oval Forever

There are a few different one's.

At first most went with the PSD one as it was ford and fit our body style truck.

Some nowe have gone to a Generic one from E-bay.

I have a spearco I am going to use. I know a few running it also.

What sizes?? I use a Cartech Turbo Systems one on my Stang that is 30x3.5x18. Its also a twin I/C.

Blue Oval Forever

My spearco 22"x7" (w/o tanks) intercooler

I will post pic's on it and a PSD.

just give me a bit to go out to the garage and take some.

turbodgumby

cool thanks.

Blue Oval Forever

OK here is the PSD







This is the spearco

turbodgumby

the spearco looks like it sends most of the air through the middle instead of across it more evenly??
Here are some pics of my turbos and my intercooler.. Also my present twin turbo project. I am going to use the same style intercooler on the lightning.

Man 800HP is a lot of power to shot for. I now the parts you have won't get you there. This is from a person that has been there and done that. The header you have won't get you there. 15/8 header are to small they have to be a least 13/4". The T70 won't flow the air needed to make the power at low boost on pump gas. Race gas yes but not on pump gas. The PSD IC is fine I make 1100HP at the tire with that IC. Its cheep easy to fit and lower the temp 80 to 100 degrees.

Stoking it? yes it will help big time. The problem is the block. the block won't put up with the power. You can put a girdle on it and leave all the stock parts in it crank rods and piston. with some heads and make 600RWHP and it will live all day long. I made 580WHP and 711WTQ for 4 year and never hurt it.
But if you try to stoke it its going to be too much for the stock block at that power level. Because of the added weight of the throw.

EFI
Stock computer I don't know. I tried it and try and try and it never worked. At the time [1999] I wanted it to work because I had just spent $3000 gran on a P&A Pro comp E4OD trans,which I still run to this day. I put a F.A.S.T and a Baumman and never looked back.
With twin turbo of that size there no lag at all. The boost is on all of it at 3100RPMs and so is the power, mine make power 700WHP on 10LB from 3300 to 6200 and that were it shifts. it a big low RPM torque monster.

You can drive down the road at 50MPH and have 10in of vac at 3000 4000 or 5000RPM depending on the gear it in and stomp it and its going to go right to boost. [and the truck going to dead sideways on you.] And the stock computer just cant deal with it. The boost on a Turbo come in were ever the engine ask it to. Turbos put boost to the engine to load. the more load the more CFM it feeds. Blowers feed CFM to RPM. Turbo aren't driven by the engine there driven by heat. the more foot on gas the more fuel in engine the more heat in pipe the more boost. If the computer can't see the boost it can"t do the job. It will eather go dead lean and backfire or go dead rich and fall flat on its face. And you can"t drive a the injector you need with the stock computer. [about 83LB for 800HP].

Fuel system
The bigest and badest you can get. no front tank. sump or a cell in the back. 10AN feed line up 6AN line back. Fuel rails. and a BG King sumo or a Aeromotive Eliminator or Pro pump.


I would Build if it was me a 408 sportmen block, Trick flow trackheat ported heads. Cam motiom cam costom grind hydraulic Roller cam. Nothing off the wall. Trick flow 351R[not the box] intake,80 or a 90MM TB. 2 To4R or TO4Z turbos with a Q trim 58 or 60AR hot side. 3.5" down pipe and 3.5" or 4" exhaust, 13/4 headers. PSD IC. and A badest E40D you can get with a 3500RPM PI converter with lockup.

And it should go 10.90 @126 in the 1/4 on pump gas.


My truck goes at 4400LBs 10.90 11.0@ 126 or 8 on 10LB and pump gas. 10.30 or 40 @133 on 22LB race gas, and 10.0 99.9s@145 on 30LB of boost. on 2 [to small for the engine] T04E 58mm turbos.

Must done something right

DallasGT01

you do realize he said twins right???

twin 67s will get him there those turbos are rated to 780 i am thinking.. EACH....

thats almost 1600 flywheel...

nm... Didn't see Gen 1 truck

Yes I know he said Twins.Your your right 2 67mm turbos will SUPPORT 1600hp at max boost.not make 1600HP but support it. You can't just bolt two turbos on something and it makes the power they say the turbo will support.
That just means that the turbo will move the CFM it takes to Support the fuel it takes to make that much HP. That not the IC loss ,heeds, intake, TB loss or the cam your useing. Theres a lot to it then just that.

A T76 will only support 850HP on 30lb of boost. now turn it down to 12lb and your only going to make 550 600hp.

Ever time you 2x the boost of a turbo it 4x the CFMs output.
with that being said he wants to make 800hp on pump gas. 800hp is a lot air.about 2200CFM to get that kind of air at 10 to 13Lb of boost [2x the boost = 4x the CFM] is not easy. there some good size turbos to do that. and its going to take an engine that make 500hp off the boost to make 800 on the boost on pump gas.

Just look at all the 9.0s and 8.90s pump gas cars running around. What are thay doing? there 800 to 900HP. There running twin T76 or T88s on 10 to 14 LB of boost. Or running on E85 or have a snow kit on them.

Its not that you can't make 800HP on twin T70 you can do that at 22lb. but your not going to do it on pump gas. And your not going to do it on 15/8 headers.

idk how you couldnt make 800rwhp on pump??? there are 6 7 03 cobras doing it...

skidmarkracing

no kidding, I put 858 on pump with a single turbo and a 5.4
