Cool build - now back to reality, what's that likely to cost?

Dave

Probably like 10k GBP. Oh wait, new block, so maybe 30K GBP...

Block 5000, crank 3000, rods 1200 , pistons 800+ , intake brouh ha ha! exhaust 1200, dry sump 1000. And machine and labor and managment and dyno and clutch...

I find it more interesting that they're getting these large HP figures from motors that don't rev to the moon. 280hp @ 7500rpm from a 2.3L is pretty damn good.

My guess is that it's all in the head porting combined with a damn good camshaft.

meh...a Mountune Duratec makes 8 more horsepower.

That's the endurance spec Formula Atlantic motor. The more high strung version is more like 320BHP from 2.3L.

My friend Jack that linked me that was a crew chief on a Formula Atlantic team for a few years. The 280ho version was very durable he said.

Do you want to know?
Really? Cause you won't get it by guessing.
And 7500 IS a chunk higher than typical in the last say 10-15 years for 2,0 to 2,3 motors in rally use in the big gravel countries.

Thanks for making the obscene amount of bucks I've wasted on my car look like sensible fiscal policy.

They didn't say anything about porting on the Duratec, did they?

First thing is the tq numbers are in NM not ft lbs....so about 200 ft lbs. Hurst drives one of those in the Capri, which is pretty neat but he says it isn't any faster than his old Chrylser street car with a 3.5 V6 above 60mph.

To keep this G2-G5 thing in perspective...You're looking at tq numbers from a pretty pricey race engine. My son's 2.2 Ecotek was dynod at 225 ft lb at the wheels with 10 lbs of boost (supercharged). That kit cost $2600 from the local Chevy dealer and we installed it in a day. Now if we worked over the Ecotek and upped the boost we would easily and reliably be well past 300 ft lbs and no where near the cost of that NA motor.

The reason we keep noobs out of G5 is the easy and available excess power. G2 can go plenty fast but they can't match the raw in your ass slam of the big torque available in G5. So far the formula seems to work.

206 ft/lbs

And what the motor doesn't make for ft/lbs a 5.1 axle ratio can.
If the newb rule was to make any sense, then the final drive in newbie Gp2 cars would also be restricted.

Yup 206 ...which is about 200...no where near 279. Pete was all over it, just missed the nm clue.

The rule works pretty well. Most cars don't have 5.1 axles available and that ratio really limits top speed and you're shifting every 20 seconds one way or the other. A good boosted motor like that Ford or Ecotek doesn't need to be hindered with a 5.1 and will pull like a freight train in 5th.

Currently there are only a couple cars in the US that have any serious effort spent on the them. I think the majority of people realize this sport is for fun. The fame and fortune from winning G2 or G5 (or Open for that matter) vanishes long before the credit card debt does.

What's a decent terminal speed to plan for, incidentally? I mean, in theory at least, some of us might be looking at something even steeper than 5.1:1.

I think a top speed of 115 to 120 MPH is a good target.

Before I spent that much on a motor I would buy my self the whole car like the A7 Golf's we had out here in WA a few years back. I think $40k would get you a nice 220-240 Hp golf with the xtrac 6 speed sequential and big old scary proflex, huge AP brakes, massive knuckles etc.

Hell for a few more bucks I could buy Toni Gardermister's BMW as a whole car with seats and stuff.

Hmmm, that's what I was hoping to hear... that allows the nice big scary 5.71:1 rear end ratio even if I plunk down the cash for a close ratio gearset later on. Noice.

Have to admit, the fact that most people do under-prepare their cars is one of those reasons I'm scraping together the cash for this instead of running a roadrace car. It's looking like probably something around a quarter the cash outlay compared to the classes I'm familiar with, even if the rally cars could be built a lot farther within the rules.
