Big Cubic Inch SBF combinations

[2Fast4You]

Anybody have some great input on making big power w/ a SBF combination, N/A or Power Adder?
Let's talk success here and give some other Bangerz a little input.

I'll let you know in a couple months.:lol: For now I'm gonna the 427 n/a at a compression of aprrox 9:1. Using a sold roller n/a cam, hopefully a regular vic jr 351 intake converted for f/i and stock vic jr heads. I'm shooting for close to 500 at the tire but may be a little stretch w/ the compression. I could go turbo but that would easily put me in the 800-1000hp range and I don't feel like paying for all the supporting mods yet so just gonna be an under achiever for now.:bigthumb

You deffinetely have the cubic inches on your side. Just think, you can make all that power on pump gas. I am looking at big cubes running 12.5:1 compression w/ a custom solid roller for NOS. I want to put down at least 1000HP at the rear wheel. Not sure what the best crank, rods and piston combination is going to be for this? I am going to run the Victor Jr. heads as well.

Big hp with n/a sbf. thats my build!

[adragon72]

I don't know if you would call it big numbers but I have a 331 9.1 comp, GT40s un ported, novi 1000, victor intake and it made 495rwh.

408W with an ebay turbo. 16PSI at 4500, and it bled down to 11PSI by the end of the run. Once I get the boost control worked out a little better, it should pull a bit higher.

Im thinking off going with a 408 your motor and turbo combo is pushing some pretty good numbers thats the numbers i want too push what heads u got

I thought you were going to build a motor for 8.5?

[Paul408Notch]

Canfield heads, spyder intake, Fast XFI

[2Fast4You]

I thought you were going to build a motor for 8.5?

I want to be able to run that class and maybe be flexible enough to run another class as well. Is there something I need to know about that class that I need to know that with this combination would prevent me from being able too Adam?

That's some good numbers, are you running NOS on that yet?

[2Fast4You]

What kind of numbers you looking for?
Is there a specific class you want to run?

[2Fast4You]

Canfield heads, spyder intake, Fast XFI

Those are some good numbers Paul, what kind of boost control are you going to go with?

[2Fast4You]

Where can I find all the class regulations for the 8.5 class?

[Adam@S&MMotorsports]

Where can I find all the class regulations for the 8.5 class?

They are posted on extremestreetcars.com. There are several rules to conform to as well as knowing what combinations will work well. Give me a call if you have any questions.

How many pounds of boost your running ? this is about where i wanna be with the cobra , not trying to set the world on fire just a fun little street car.

Here is a link to the 8.5 rules.

What kind of power is that combination making?

[adragon72]

no i havent sprayed it. i really dont think it will take the spray at this point.

some were around 8lbs i believe.

[Paul408Notch]

I'm letting the XFI do it. Just have to get it dialed in a little better.

[2Fast4You]

Paul,
Is it true that you have an Ebay turbo kit on your car?
How in the world did you ever get it to run again and make that kind of power?

[Paul408Notch]

The turbo is some cheap Chinese turbo that originally came from ebay. The cold side is all ebay piping. The hot side is a hacked up BG kit.

I'm not sure what you mean about running again with that power. I built the motor for a turbo years ago, and now that it finally has one, it really likes it.

[Blowpastyou]

Big inch windsors don't make any power with turbos... Now big block chevy's on the other hand.....

[JASON408]

i run a 430 with some high ports about 13 to 1 everything built for spray . made made 570 na to the wheels thew a auto first pull to 7k then my starter broke so did not get anymore pulls . runs 9.80 at 140 na with a very tight tight convetor and in outlaw trim will run 5.40 at 130 on 8.5s on a 350 shot. i run the limited 8.5 to but cant spray as much becuase of the jet limit but most of the cars in the class are prob 650 to 750 to the wheels cars and run 5.90s to 6.20 . its very fun and all the guys are very helpful so if you got any more quetions just ask

[TurboNG]

I make 452 wheel hp N/A on a 349 @ 9.5:1 comp at like 6000rpm gonna mb do a custom Cam and up the Comp up to 11:1 and turn it higher to 7500rpm should make 500 wheel hp then thats not bad for a 302 base motor....

This is good info guys, all this can do is to help guys that have less experience in building HP.

I have a 393, TFS TW heads TEA ported, out of the box R intake, flat top probe pistons, run it on E85, stg 3 TFS cam, mid length 1 3/4 headers, made 470 to the rear wheels on a mild tune. If I put a vic jr style EFI intake on it, solid roller, and it would make a bunch more power. It made that power peak at 5400 rpm's.

Mike,
When you stated TEA Ported, what does that mean?

[Blowpastyou]

Total engine airflow. Its a company

It's always nice to learn something, that's exactly why this thread was created.

Is this your NOS motor?

[TurboNG]

No that motor is in Barny the Purple Dinosaur..
His 9 sec car is a 308 stock cam, out box heads, ect.... (Rs) car
HP dont make fast cars HP to weight combos with 1.2s 60fts make fast cars ;)

[NXcoupe]

Dave is correct. This could run nitrous easily and was in the initial plans of the engine build. It's a long story, but I just put this together to see how it would run and let a buddy of mine drive it and hear it before it gets parted out. We are going to take it to the track one more time with a gear change and trans repair, it should go in the tens pretty easily on slicks. Big cubes are nice, but especially in an 8.2 deck engine which this one is based on a 9.5" deck.

[2Fast4You]

Is anybody running the shaft mounted or the stud mounted roller rockers and why?
What brands and ratio are everyone using?

[03z06vette]

Im using 1.9 shaft mount Jesel .. just because im gonna be running high rpms. stud mount are fine for the normal 7000 and under rpm engine.

That is what I was thinking as well, I was told the combination I was going to be running I more than likely will be turning 7600-8000 RPM,s.

[2Fast4You]

I currently have forged aluminum stud mounted roller rockers but need to convert to the shaft mounted rockers. I am still at this time going to run a PG trans with a trans brake and it shifts electronically through the valve body. all I have to do is hook the lead up to an RPM switch in the ignition. I currently am going to utilize my existing 4500 stall converter w/ this combo as well.
