How much hp/tq would this combo be?

[loud2004marquis]

Having Stainless Works exhaust and doing an Eaton Swap with a 2lb. lower and 3.00 upper (metco), where do you think I would end up as far as hp/tq?

You may want to reconsider that upper pulley size with a two lb lower, that's going to give you some pretty big boost (like 15+).

I'd recommend staying with a stock lower, or if you go with a 2 lb lower, using maybe a stock (3.6") or 3.4" upper.

I'm running a stock upper and 2 lb lower and that's good for just under 11 lbs boost, 430 hp/428tq.

Boost might even lower with the exhaust???

Which would be good for the stock motor.

DTR + 4.10's + Eaton swap = Wreeeeeeeeeeeeeeedom

Bout ready to put that eaton on? I'm trying to get some parts together as well.

Yes, free flowing exhaust will lower the boost pressure while increasing the horsepower. Efficiency is a wonderful thing.

Keep your fingers crossed its under 450.

Thanks Rex!

Still researching and collecting the last few parts. It will be late fall or winter this year when I start. Want to take the car to the strip and run it n/a to see what it does. Your gathering the parts too! How far are you in your hunt?

While that seems to be the "magic" #, I was @ 472 RWHP on a stock motor for over a year, somewhere around 11lbs of boost.

Zack was around 490 for a couple years on a stock block till he upgraded.

I've been at 466 for almost two years with no issues. I am bored with that and upgraded myself to play it safe.

Most here know how him and I drive our cars.

H.P. has very little to do with remodeling a block compared to AFR, timing, and boost pressure. Not too mention centri's can push them safely into the very high 400's.

Yea that would be a great comparison, and fun too. I would be interested in running to a drag strip with ya. I'm not very far at alli wish I could just drop the car off and have someone else do it. I hardly have the time.

Looks like all 3 of us in the Hunt :beer: I have been slowly getting a part here & there it's kind of fun and it's at your own speed .

^^^^^^ Yup. Too much timing and not enough fuel makes 'em go BOOM, even at much lower HP.
