I have to ask, Whats under the hood on this thing??

The pace car.
Is there actual footage or photos of the inside of the engine bay?
I can never seem to find anything about this.
I'm curious as to what is under the hood of this thing and how its configured.

Re: I have to ask, Whats under the hood on this thing??
It's the hot 3.4L 225BHP GM motor that they built for the three official pace cars.
There used to be a video on youtube of the engine bay but I don't know where it went.
I also have photos of the bay at home...
This same magazine article goes on to describe the modifications to the 3.4 V6/60 engine; the main points are listed below:
Bow Tie aluminum V6/60 block, bored to 92 mm diameter
Billet steel four-bolt main bearing caps
Production 3.1-liter crankshaft, main bearing journals were cross-drilled and micro-polished
Prototype cast-aluminum pistons
Priority main feed oiling system modeled after the small-block V8 design
Production "Generation II" aluminum splayed-valve cylinder heads, ported and polished, combustion chambers relieved enlarging them from 28cc to 34cc, producing a 10.7:1 compression ratio, Iskenderian valve springs, titanium spring retainers
Crower solid lifter camshaft with .459-inch max intake lift and .484-inch exhaust lift, Iskenderian solid lifters, custom-made Smith Brothers pushrods, Crane aluminum roller rocker arms, special studs from Ryan Falconer Racing Engines
Production 3.1-liter intake manifold modified with 1.25x2-inch runner tubes 6.5 inches long, custom built stainless steel fuel rails with .5 inch primary tubes and 5/16-inch secondary tubes, high capacity fuel injectors from a turbocharged 3.1-liter V6
Fabricated intake plenum equipped with a production Corvette L97 throttle body, custom PROM for the ECM
4 speed automatic transaxle
Custom headers, single high capacity transverse muffler in place of the spare tire
Twin ram air inlets behind the grille feed a pair of high-flow filter elements for the air cleaner assembly
Water pump had every 3rd vane removed to reduce coolant flow through the block at high engine speeds
Engine mounts filled with polyurethane, upper radiator support reinforced, second torque steer strut installed, diagonal braces from upper radiator support to the strut towers
Aluminum half blocks replaced the steering gear's stock rubber mounting blocks, metal bushings replaced production tie rod bushings, stock 14:1 steering gear ratio was retained
Corvette electric radiator fan, battery box relocated and radiator core moved forward for additional clearance, auxiliary coolers for engine and transmission oil mounted in front of radiator core
Production Beretta GTZ brake system augmented with modified Corvette Z52 front disc brakes, high-metallic front pads, high-capacity rear drums, front suspension features a '90 Beretta direct-acting stabilizer bar, Beretta GTZ springs, Delco gas-charged front struts and rear shocks

Its been a while since I read this.
I wish they made our 90 beretta's with this engine. It would have been a lot more fun.

It's a nice piece of history but you can make so much more power these days. The headers are nice tho.

Yah, but I mean for an original Beretta INDY, I think it would have been better if they used this engine instead of the standard 3.1 MPFI.3X00-Modified wrote:It's a nice piece of history but you can make so much more power these days. The headers are nice tho.
I think it would have made them worth more and more rare.

That is about a $20,000+ engine all custom made and/or fabricated and modified to work on a very limited scale. They required that level of power to qualify as a Pace Car.GHOSTOWLGRID wrote:Yah, but I mean for an original Beretta INDY, I think it would have been better if they used this engine instead of the standard 3.1 MPFI.3X00-Modified wrote:It's a nice piece of history but you can make so much more power these days.

There was no attempt at all on GM's part to make the production Indy's rare or collectable. It was simply an attempt to sell more cars. THAT is all they care about!

I should really get my vid uploaded and on here. I did a full walk around on the pace car, including underhood vid. And LOTS, and crap-ton of pics.

No he just said they would be very disappointed if they showed up on youtube or something... LOL
Re: I have to ask, Whats under the hood on this thing??
I'd love to see those. I find this car so interesting!3X00-Modified wrote:I have quite a few under hood pics as well, and underside of the car.
92 GTZ 3.1/auto, no real mods other then a strut bar, I fight hard enough to get it road worthy!
