Evos without lots of suspension work typically look a little more like this with sticky tires.....

I loved driving that car.

Damn!

Talk about inside rear wheel lift!!!

Scooby South · 02-09-2007, 04:20 PM

Do Evo's benefit from Bigger Front bars like Impreza's do????

handling wise

Anyone know where the weight and power of a typical 2.0L or 2.2L BSP S2000 would be?

2800ish or so

Chiketkd · 02-09-2007, 04:34 PM

Thanks. How much power over their stock 240hp can they make with an intake, full exhaust and an ecu tune?

Chiketkd · 02-09-2007, 04:35 PM

Looks like my answer is in post #10...

Also, my stock legal car weighed less than 2700 pounds on the scales in '04. Another big advantage for them is good suspension geometry. All the camber you can want STOCK. Oh, and a 50/50 weight distribution.

A well setup S2000 will probably not have HUGE bars. The enormous front bar thing is a carryover from stock. Anyone worth their salt will properly setup the car and lose the huge front bar. A well setup S2000 will lift the inside front tire off the ground at corner exit (mine did) and will slalom like a CSP Miata. Spring rates should be at least as much as noted above, particularly in the rear to limit the dynamic toe changes under bump.

The cars should be able to make between 250 and 300 horsepower in SP trim, but there's not much extra to wring out of the engine. Honda took almost all of it in its stock form. The big powertrain item is the rear differential. The OE torsen unit (aside from being a little on the weak side) is prone to wheelspin when lifting the inside rear tire off the ground. While suspension setup can largely fix this problem, a good differential will solve it. Of course, this just results in the car being NASTY to drive, as you'll light up both rear tires mid-corner if you're not careful. If you're going to beat the S2000, you'll do it with gearing. The AP1 cars will reach 65mph in 2nd gear, but need to downshift to first below about 35mph. The AP2 cars can lug 2nd down to around 30mph, but need to shift to 3rd at about 60mph. Neither of these cars has safe headroom to be raising rev-limits without serious internal engine work. The only other way to beat them is in the slick conditions. The cars are wicked when its slick... damn near impossible to drive fast.

btw Rita's 2005 BSP C4 weighed more than my AS car.

Huh? Previous posters have said that the S2k can get to under 2700lbs in stock form???

I think I've probably taken my S2k further along in BSP development than anyone else... Bone stock my car was 2770 on a full tank with the spare and tools removed. A reasonable weight for a well developed BSP S2k will be around 2530 full tank (my car is a little heavier than that)... S2k's fuel starve easily and don't always recover from it gracefully so you're better off running full tank vs. the weight savings imho. You could probably get to 2500 on a first gen (AP1) but you're probably splitting hairs at that point and compromising setup (i.e. lighter wheels at the compromise of proper wheel width, etc.).

I'd expect Dynojet numbers for a BSP S2k to be ~220-230 on a 2.2l (AP2). And maybe 10-15hp less on a 2.0l (AP1) but the AP1 will have gearing advantages on faster courses. Not considering the ud/bd possibilities obviously. You can get more peak hp at the cost of mid/low-range but that's a bad idea imho...

Here's another great Mako pic, my Evo bone stock including tires... If not on 2 wheels, pretty close to it.:

True but it also still had a lot of stuff that could have been pulled under SP rules, that car could have lost 100 lbs.

btw check that S2k link of weights. The 2nd lightest C4 in AS, French, was as auto and he was only 10 lbs over me.

I think Rita's yellow car (w/ 4pt rollbar) was sub 3000 or very close to it... I have seen top-level BSP L98 C4's on scales at close to 2900 (~ 1/2 tank)

I started autoxing after going to an event and watching Rita. Even bought a Corvette because of that, that I prepped for BSP, that I still have. No jokes here...

I think Ramey got his 96' LT4 car down around 3000 lbs, so it can be done.

No doubt that is one fast Grandma. She also just bought back her AS C4, she then took it to an event and put away two time AS champ McWho.

For whatever reason the Z06 was not her bag, she did ok in it, but man put her in a C4 and watch out.

This varies widely from car to car. I ran mine with 3 bars of fuel without starvation. I know people that couldn't run with less than half a tank. No one seems to know why this is, but some cars are better at picking up the fuel than others.

As for weight, Andy McKee speculated that the scales in Topeka in '04 were heavy by 25 pounds or so. He swore that my car (previously his car) weighed closer to 2650 on other scales with similar fuel loads. I doubt all of that difference was gained in A3S04's over A3S03's.

The next funny thing was that moments later I told Tom ... "Hey, I got that on (sic) film, and it's for sale!" He should have bought the rights right then and there and had me erase it! hahaha

Are you familiar with Jason Uyeda's car? He did a great job with it. Moton, ITBs, etc.

I'd be more interested in seeing the torque numbers for a well-done BSP S2k. Torque is where it's at when you're driving off a 25-30 mph corner...

That is Jason U posting.

Duh...

Jason - care to share your torque numbers?

Care to share yours

Should be about 165-175 on a Dynojet for an AP2 and again I'd guess ~10 less for an AP1...

I'm running Ankeny built Penske's btw...
