How much H.P.
 

I am sitting in front of my computer while waiting on a guy to come pick up a boat that I don't think is going to show, so here you go. I have a 511 cu" BBc in my 28 Pantera It currently has twin turbos on it now. ( actualluy it did ) I have removed them in order to go with either an 8-71, or a procharger, or Vortech. The motor is a tall deck 511
4.250 stroke X 4.375 bore It has a good steal crank, Carillo rods, JE pistons, ceramic top rings-gapless second, It has been o-ringed and reciever grooved, It has a set of ported 990
heads, copper gaskets already.Dart single pane intake as of now. I am still alittle up in the air about the induction I want to use, (I wouldn't mind keeping the turbos in a way but they quite down the exhaust a little to much for me.) I like the power claims from the prochargers and vortechs, however I like the cost of the 8-71 a little better. Any one want to take a
comparision shot @ this ? also what kind of power should I expect with either of these setups especially the 8-71. I realize that I did't give any cam specs. However It will not really come into play because it will be changed acordingly. Also If anyone is interested in a complete twin turbo setup , twin carb setup , extremely large PFM intercoolers ( double the normal capacity ) Rayjay 301 e 10 turboes, Exhaust Ect.... Even the cam if someone wanted it. Send me a P.M. and we will talk. I have alot of pictures of these. Thanks Guys, Scott

Thats a hot Setup!

How much boost were you running?

Re: How much H.P.
 

I just recently bought the boat and to make a long story short I ran it one time , and was having what I thought originaly thought was a condensation problem due to low oil
temps , along with a cold charge from those intercoolers. However I have since found out it is a leaky head gasket problem. So I didn't want to run it much untill I found out if it was condensation or not and now I am glad I didn't. I bought the boat from an old man who had the boat for 15 years and hardly knew the differance between boost & power trim!

Re: How much H.P.
 

I can appreciate the Idea of changing to a roots.
However That setup with the right components
which sounds like you have is far superior.
Run some good Cometic head gaskets and
Reassemble it I think you will be happy.
I dont know your capabilitys but if you reassemble
that correctly You will have A Strong setup.
Pressure check the intercoolers. Is the manifolds
and turbo housings water jacketed? if yes then have them
checked aswell.

From my view the old man who owned it for fifteen
years may have not known the basics but, someone
he knew did!

Good luck :drink:

How about a pair of 588 quad rotors?? One to run and a backup. You can get a rotation going with rebuilds...and run like a raped ape!!! :eek:

:D :evilb: :drink: :evilb:

Re: How much H.P.
 

You still have the Sonny leonards?

Re: How much H.P.
 

Yep....they are coming out of the boat in about a month if they don't sell and I'm going to sell the parts off of 'em. Heads, intakes, innercoolers, blowers, cams, pistons....all of it except for the blocks, cranks and rods.

Who wants a spare set of motors for a Poker Run beast????? :D :evilb: :D :evilb:

Re: How much H.P.
 

Sounds like a well built engine. What compression and cam?

A pair of 301E turbos will only move enough air for about 750 HP. That's a lot of hardware to deal with for only 750 HP. The 8-71 can easily deliver that much HP with an intercooler and is a much simpler installation. A single centrifugal/intercooler/blowthrough carb on that engine can deliver 950 HP and is also very simple in comparison.

I don't blame you for taking the twin turbo stuff off. I've been down that road too and decided against it.

There used to be a 28 Pantera in Sandusky Ohio that had twin turbo's and a Stern Powr Outdrive.

Re: How much H.P.
 

Thats her. Do you know the boat ?

Re: How much H.P.
 

Tomcat I sent you an e-mail saturday if you havn't seen it, take a look at it when you get a chance. Thanks , Scott
Keep it comming guys. How about the 8-71 without the intercooler? Although I would feel much better with an intercooler.

Re: How much H.P.
 

No I don't know the Guy that owned it.I looked at I once,but the twin turbo's scared me away.This was ten years ago.
