I'm just curious about how fast these super light cars are. Anyone have an idea of these times with different sized motors? I'm looking at either a spyder kit or speedster to build myself. I'm a Porsche nut and race vintage 911's. If you caould post times that would be great. Also any new infor for a newbie that I should know before ordering. Thanks,
Chad

Chad,

I have not timed my spyder. But, I raced against a new Corvette Z06 about 1 month or 2 ago. The guy could not beleive that a 2.3l VW Type1 engine left his brand new red Z06 in the dust, of course he did catch up, but not before we reached 100 mph :-D My car's weight is 1150 lbs with approx 180hp and the 0-60 is somewhere in the lower 4 seconds and it tops at about 135 mph with a 4 speed transaxle. I highly recommend to restudy the aerodynamics of the Spyder if you want to go faster, because it may take off without adding wings.

550 Spyder => "Giant Killer"

Hey Chad,

I am one of the guys that enquired about your old red RS clone. Anyway, I have not "formally" timed my Vintage 550, but can say my experience is pretty much like Martin's. I have a 2.1 liter Type 1 in my car and am running at about 1200lbs. Zero-60 is somewhere around 5.5 seconds by my reckoning. I can also echo Martin's comments about hanging with other cars with heavier iron at least up until around 90-100mph (I have personally done so against a Viper). However, the front-end begins to get really light and it is serious white-knuckle time from there on.

I would think traction would be the biggest accelleration problem for a Spyder replica if you have over 150 BHP and a 1,200 lb. car. Of course a ZF limited slip or torque-biased differential would help if you have wheelspin problems.

My new (in process) IM Speedster will weigh in at about 1,800 lbs. and have a 200 to 215 BHP 2,387cc type 1 engine hooked up to a custom close ratio 901 5-speed and torque-biased LSD. Hopefully 0-60 will be in the low 5 range and 1/4 mile in mid to high 12s.

A Spyder with IRS instead of swing axle rear suspension would be nice...
