1985 IROC Z vs 1999 528I BMW

Hey

One of my buddies wants to race me in his BMW. Its a 528I 4 door car with a 6 speed trasmission. Do u think that I have a chance against him or what...

Thanks

Yeah

I smoked a 2000 528ci 4 door when my car was still a TBI 305, I did everthing you could do (chip, ram air, headers etc., gears, 1.6 rockers) and I gave him a head start and still won. - it was an automatic though

I think you have a very good chance. Though I don't know a lot about the BMWs, I took a convert one when I had the LG4 with headers.

You shouldn't have much trouble with him. It's not an M series car. Sure there are quick bimmers out there besides the M series but a 528ci is not one of the quicker ones.

You'll have him for sure. I raced a 328 when I had my stock LG4 and just edged him. 5 series is far heavier than the 3 series. Happy killing!

My ragged LG4 with headers/exhaust is about dead even with my good buddy's 1995 325iS right up to about 130. Then he pulls, but that's where those cars *really* shine, right?

Are u guys sure about this. I have a 1985 IROC Z with a 305 TPI auto and 3.42 gears. Hes got a 1999 BMW 528I with a 6 speed. Im not sure if I will win.

Does anyone have 1/4 mile times for his car.
Thanks...

They are rated at about 180bhp and far less torque than our cars. I would guess they would weigh as much if not more with all the luxuries synonimous with the Marque. I had 2.73 gears when I left him, and it was from about 60- 120 mph- when I backed off.

Like I say I think you will definitely take him.

My wife drives a 525i. Based on my experience with this car, I think the race will be closer than it may seem. If this guy knows where to shift to keep the engine in it's optimal power range, it will be interesting.

Please tell us what happens.
