Engine and Transmission Tech

They could at least, give Jim Stabe credit for the "Pfat" idea ? Whaats the budget, for a lap record ? Needs Batman to drive. So far out, why not mid ? Good Show, roverman.

Hi guys,

Just wanted to say, that the idea for this came about in 1995, so it was well before this forum was formed.. The first V8 was actually bought in 2007, so it's been planned for a long time, it's only now when I've got the opportunity to build it..

Work is going well on the engine.. We are about to have the liners fitted, we've done all of the mods to get the block able to be machined for the standard lotus bolt pattern.
We have designed and made new bottom end caps for the block to make it strong. We will be using the standard'ish spec Lotus cams and timing,mas we are using a steel flat plane crank..
In the new year, the new front cover for the timing belts will be made and hopefully by April/May we will be ready to fire her up!

There is a full build of the car and engine at www.facebook.com/APSMotorsports..

We're quite open about the build.. It's been my life Lind dream to build this engine and our MGB GT3....

Cheers Peeps!

Jason, what are you doing about the head studs if I might ask? The bolt bossed in the block could be a bit stronger and certainly may be considered marginal for the sort of engine it sounds like you are building, then relocating the studs adds another question. Just curious.

Jim

Jason, Will you be using a "girdle", in concert with the new caps ? A crank like that, in a 90 deg. V8, especially with moderate stroke, creates sizeable force/couple harmonics, directly to the main bearings/bulkheads. Target hp. is ? Not using a Coscast block ? Good Luck. roverman.

Pete Aardema says this engine build is covered in this quarter of "Racing Engine Design", GB. Where to buy ? roverman.

I bought the magazine with the car in,they are hoping to develop a kit to market the heads !
Billet sump,with longer studs to strengthen the bottom end up, I'd be interested in that,
There's no mention of the engine actually running,let alone a dyno session.
But should be going by the fall.

"Kit to market the heads", ok you got the "kit", now all you need is a 180 deg. billet crank and bottom end strong enough to take all of the harmonic hammering, fab-up a well designed IR inlet system and exhaust, OR slice and dice (4), 907 cams, like Fred did, to use the V8 crank. Sounds easy.... roverman.

Got the magazine at Barnes and Noble.
The two pictures shown were mock-ups.
Twin turbos, intercooled "each turbo capable of 650 hp."
"Camshafts specified for an output of 600-800 hp per cylinder bank."
"Maximun rpm,9300" "estimates engine should be capable of 1200-1300 hp using about 30 psi boost."

I think that's too much to ask of a Rover block.

Jim

Jim, I think you're right ! A few 1/4 mile passes-maybe, but the big-N, in Germany ? Big funding and big hp., I'd start with a Coscast block. Bang for Buck, would be TA heads, just not as cool. Onward, roverman.
