Default 9sec 93 octane setup?

Ok what kind of motor combo and turbo would it take to get a 9sec car on pump gas. Car is set up for the strip car is at about 3000pounds NA so how ever much weight to get a turbo and intercooler set up on there in added weight. Then what would this set up run on race gas?

id say go with a forged 346, get a 76gts turbo and run mid nines on pump gas with that race weight and low 9's high 8's witha good driver on race fuel.

this way, you dont go with an iron block, and will only add a couple hundred pounds at the very most.

At that weight you might just need like 550-600rwhp.

I think 600rwhp on pump gas is doable (no meth too).

I'd do a 408" iron block with a pair of T66's. That's what the Dark Dragon vette ran, and it made over 1000 RWHP at 13 pounds of boost.

Some cubes north of 400ci, compression around 8.7-9:1, and a 76-80mm turbo with boost set to meet the ET goal for the specific fuel.

I Ran a 10.09s pass on Sunoco 94 pump gas before the summer heat slowed my quest down some.

A big stroker motor is just going to choke off a 76-80mm turbo and I wouldn't doubt if they made less power on pump gas than say a 346.

On pump gas.... you would be wrong. Ringing it out to peak boost... we'll see.

So what go with
408 all forged 8.0:1
t88 -91.5?
Water to air in the car

or can i get away with like
360 8.0:1
t-76

BEcuse the only dif in cost between the 2 setups is the cost of the crank on the strocker motor.
I drive the car about 1 time every weekend out to some street races and besides for that it is a track only car.

thats what im planning on....it WILL be doable.

White98Z you really dont NEED as much power as you think to go fast.....if you have a rear,full suspension and all the prerequisites then you really only need about 600rwhp give or take to tap into 9sec territory.now if youre trying to go as big and as fast as possible...thats a different story....and remember if you go with a 408 ur adding alot of weight to the nose of the car as well.just my $.02

Well just 9sec on at pump gas on a tune that is not pushing the motor that hard. Then go 150mph on race gas.

Here is what the car will have got it have not got it installed yet.
wolf double sway bar
wolf torque arm
Wolf rear control arms and panhard
Wolf wheelie bars
wolf parchute
wolf 10 point cage waiting for there funny car cage to come out
Ford 9in 35spline with a spool
BMR K member

What i am going to to be buying is
Hals all the way around
Strange breaks
Motor plate
Glide or Th400

So i am wanting to go pretty fast on race gas just want to be able to drive it to the track or a true street race with the cruise and go 9sec

Here are some pictures i took of the car about 9 weeks ago

No, I wouldn't be. I helped a friend tune his ford, it was a 8.5:1 compression 408, aluminum heads flowing 325/255, vic jr. intake converted to EFI, and a precision T76 GT-S trim. Couldn't run more than 12-13 pounds of boost on 94 octane or it would knock horribly, exhaust backpressure was right around 40 psi, and we were blowing header gaskets and seeing valve float from so much backpressure. That exact same turbo on my 347" 9:1 motor did an easy 16-17 pounds of boost on pump gas with similar timing, no knock, and it made a lot of power on pump gas.

On pump gas, I would be right. Ringing it out to peak boost, I would be right. You're choking off the turbine and the compressor on a big motor like that.

White98Z: I think he's on this board by Brady96Z, he's gone high 8's @ 170 MPH on pump gas with a 380" small block. In a 3000 pound car I don't feel even 150 MPH on pump gas is way out there, there were lots of cars at the pump gas drags that bested that, some with motors as small as that 4.3L inline 6 that GM makes. I prefer twin turbos over a big single, not only because it's easier for an air filter and fitment reasons, but you are given a lot more choice on the exhaust side in terms of wheels and housings to pick when you want boost. If 150 MPH is basically the peak of what you think your goals would be, I would run the stock aluminum block with eagle rods, diamond pistons, your choice top end components, and a pair of .81 A/R 60-1 P-trim turbos. Shoot for 8.5:1 compression and with good heads you could do middle 9's on pump gas all day long.

Hmmm.

1) Let's say 9.99 on pump gas, no meth, at 3000-3100 raceweight. I would say 600rwhp is your goal. I think you can get there at like 136-137mph.

2) 150mph... Well that's a different goal. You won't get there on pump gas unless you run a lot of cubes and keep it light.

3) You can get to 9.99@136 @ 3000 raceweight with a 346ci engine. I think you would need to make 600rwhp but have strong power under the curve not peaky like some of the stuff in this section. You need good 'average' power.

NEXT (Eric) went 9.7's with only about 525 to the wheel. The key to his success was his suspension. His car was heavier than yours too. his setup was simple head/cam/175 shot/stock bottom end.

Work with what you got before spending a lot of money and changing setups.


150 mph will take at least 800 rear wheel.
