For the parst 7 months i have been thinking about starting a small street legal drag car i have the time and basic knowlage to do most of the work myself. I have been thinking of joing the RWYB street challenge its a very relaxed season all you have to do is register, have a driving license, M.O.T and Tax.

I have posted this thread to see what you guys think is a good bases for a drag car. My suggestions are light rear wheel drive and easy to modify (popular).

I was thinking of a BMW 3 series 2 door, strip the whole interior new tyres brakes suspension clutch air feed and filter.

What do you guys think good idea ?

Sounds like fun to me. I guess you get a season or so practice in before you really start to challenge. There are loads of Engine swap options on the BMW so I think it is a really good base to work from.;)

An example to ponder over:
1996 328i
190bhp / 207lbs/ft
Weight 1466Kg

In standard trim:
1/4 mile 15.93 sec @ 88mph. This would put you 106th in the current championship.

Remove 230Kg in weight:
1/4 mile 15.21 sec @ 90mph - 97th

Add 50bhp & 50lbs/ft:
1/4 mile 14.21 sec @ 98mph - 64th

To be competitive ain't going to be easy, but then, if it was it wouldn't be worth doing.

Keep us all informed if you decide to do it. There is quite a lot of drag racing experience on this site so you shouldn't be short of help and hindrance :)

Data gathered from CarTest 2000, drag racing simulation software. Comparing virtual with real data (mine) this software gets pretty close (.15 sec and 2mph) if you can supply it with accurate car data.

The only thing with that RWYB street challeng thingy is they don't have drive classes. At the very least they should have FWD, RWD and 4WD imo.

Hmmmm, yes and no.

3 classes would be fairer, but life isn't fair.

If you want fair, enter one of the bracket racing classes.

Competition rules are simple. If your car is road legal, you can enter. You alone chose what type of car to drive, so if you drive a FWD that is your choice :)

Anyway, you would probably find the AWD boys wanting to race on their own or against FWD cars only, as the REALLY quick cars are RWD :)

I plan to enter the competition next year and would not be happy if there were no AWD cars to embarrass :)

Ok, well i have done a few number crunches and i recon i have about 1500 to 2000, to spend on a car. I say 1500 because this leaves more money to be spent on modifying the car, i recon i have about 3500 to spend. This is all pounds sterling might i add. This car does not need to be road legal, so insurance, mot and tax are out of the window for the time being, until i need to race then the mot will be biggest part, anywho !

I want to forget the BMW thing at the moment, and start with what i beleve to be important engine and drive.

Criteria:
Engine - 1.8L + (up to 2.5L)
Drive - RWD (prefered)
Weight - As light as possible

So what do you guys recommend if you where to do this?
What car would you choose and why, i want some reasons so i know plus and minuses of a few cars. Im in the dark about what car to choose im new in the drag scene and i want to get it right.

Nissan 300ZX. Two choices - the lighter Z31, with only a single turbo, or the heavier Z32 with a twin turbo.

Don't forget to check the engine fitted!

Should be able to get one for around £1500-£2000.

They are a bit heavy (about 1.5T), but have a good drag co-efficient of 0.3 (less wind resistance).

Not sure of any other RWD cars available in the sub-£2000 bracket.

Downside is it's a bigger engine than you're aiming for (3L V6).

If you haven't been already, get yourself to a RWYB (Run What Ya Brung) drag meeting to see what everyone else is using, what is fast and what isn't and what takes your fancy. Santa Pod has regular meetings of this type.
