How to build 700-1000 hp 30 psi boost 13b?
 
How do i build 700-1000hp 30 psi boost 13b motor.
1. Which apex seals?
2. Which flywheel?
3 And all other parts.
I think Abel Abbara has that motor, does anyone know what parts he uses?

Im guessing a hell of a fuel setup :D.

Not that much of a deal... This is the easy way: 3rd gen engine, ported on both ex. and int. Jay-Tec intake manifold, Haltech, methanol, Turbonetics T-series, G-Force tranny, Ford rear end and a few things...

Do you have a website for Jay-tec? or at least a vendor that sells their products?

When I rebuild my GTX over the summer(after I'm done playing w/ the stock port right now) I'm going to do all custom porting to it and have that big 'ol purdy T88 on the side for kicks..I'm hoping to build it up in the 800HP range....just gotta get my shop open, lol.

This was their web address:
http://www.jay-tech.com/default.htm

I think that they recently went out of business, but I'm not sure. :(

They had great stuff BTW. The exhaust manifold flange on my 20B was made from two of their 13B flanges.

Um sorry but 1000hp engine == about 10 secs. to pull up and then go down a quarter mile. rotary's dont run 30 lbs. for more than that. they run 10-15 daily but over that they only last about a week when run that high all the time. I doubt you could run 30lbs on any apex seals for more than a minute at a time.

somewhat disagree, guys like Chris and Peter have the knowledge and the experience to put together a motor that will handle it.

Peter would do it on stock 3 piece 2 mm apex seals too i bet ya

How do you build a 1000hp 13b?

the question is not so much how as HOW OFFEN!

and the answer is AFTER EVERY RACE!

So true....so true.

It could be done...but as soon as you got down the track...you have to start all over again

Crispeed is making 651 rwhp on a partial bridgeport motor at 31 or 32 PSI with a small shot of NOS. And Im pretty sure that motor lasted the whole season with no problems. Its all in the tuning.

maxpesce 02-19-02 01:07 PM

651HP is a LONG LONG way from 1000hp!!

mazdaspeed7 02-19-02 01:14 PM

651 RWHP is 813 bhp with 20% driveline loss. He did not say 1000 rwhp.

A Tomcat's fuel pump should do it.

That's still 187hp short of 1000hp :D and any Race Car (like chrispeeds) should only have drivline losses in the 10% or less range

Unlikely. A racecar still has a gearbox, diff, axles, etc, so it's going to have the similar losses.

You think the guys who are making "big power" are going to share all their secrets??? :D

once you get higer numbers the % goes way down. power is lost to heat. just think how hot your tranny and rear end would get if they had 160hp worth of heat in them. they'd melt in 2 secs. it wouldn't be much more then 700 at the crank.

Do i need to remind you that it was done on a Dyno Jet dyno which reads 15% less than flywheel? thats 756Hp at the flywheel

looks like you need reminding too, that HP loss thru the drivetrain is a dyno derived 'absolute' thing, its not how much HP is lost thru the drivetrain, its the reading discrepency between the particurlar rear wheel dyno and the true engine Hp output.

Dyno jet system = 15% less at the wheell
Dyno Dynamics = 27% less at the wheels

see my above replies, but yes you would melt it if you were TRUELY loosing 20% of 756HP

HWO 02-20-02 02:49 AM

i should also point out that Peter's 13B PPT makes 830HP with no extra dowels and he has plans for more boost, higher octane gas and reckons it should easily break the 1000HP mark

Felix Wankel 02-20-02 02:55 AM

crispeed's engine had over 100 passes on it.
