Can't help you with the math, but I think you're gonna need some help with the finances!!!

Math forthcoming....
2000 BMW 323 Ci
2.5L hp I6
chp 170 @ 5500 RPM
ctorque 181 @ 3500 RPM
Bore X Stroke 3.31 X 2.95
Compression Ratio 10.5:1
https://ams.scca.com/netForum/eweb/d...%20Process.pdf
170 * 1.25 (IT gains) * 0.82 (driveline loss RWD) = 174.25 whp * 12.9 lbs/hp (ITS multipler) = 2248 w/o adders or 2250
Do you have excessively large brakes? It's a BMW, I would assume so, +100 (in your face!)... so 2350.
Could there be a torque adder? maybe, if so then add another +100 (in your face... maybe)... so 2450
no way.
Let's try the other way around...
3000 - 100 = 2900 / 12.9 lbs/hp = 225 whp...
225 whp / 0.82 = 274 chp
OR
3000 - 200 = 2800 / 12.9 lbs/hp = 217 whp...
217 whp / 0.82 = 265 chp
Either I forgot to add something or you need to lots of luck ( I mean $).
Confirmed that the 99-00 323is/i seems like the same car as your 323 Ci.

Tim- when "converted" to ITR what car model does it become? How much needs to be swapped? I only ask as I know this is your ultimate goal.

1. Y'all are making this harder than it need to be, actually doing math. Ron's guesses are about as good as one is going to get if the question is about how much power is going to be necessary to get it in the competitive ballpark.
2. The car is listed in S - not in R and not in both. There's no such thing as upgrading to a class above any given car's spec line.

The cars here have to make AT LEAST 200whp. I've said it before...I have seen no dyno sheets but at the same weight as our ITR S2000 in it's debut and shake down, they were able to pull out and pass at WGI and we had 205whp at the time.
The 'upgrade' being spoken of is probably a 2.5, 2.8 or 3.0 swap.
You're crazy Tim. lol

Thanks Glenn, I think you got, except I don't think BMW's come with DW suspensions. Perhaps 50 adder for brakes and 100 for torque. By those numbers Tim needs to put down ~181-2 whp to make process power. Like Andy said, in full 10/10th mode, they probably make MUCH MORE as witnessed repeatedly.
