the anti can bugger the tubbys nicely,but only realy worth it if your going for the highly expensive ones


as for Launch control,waste of money if you ask me,a mate has it on his 490lb/ft wagon,planted throttle whilst on high boost setting,anti was on as was the launch,seemed "bog down",so tried without anit and launch on,a much better result ,why spend out on Launch control when "we" already come equiped with it built in??

Re: My Classic mods in rediness for Simtek and Bob Rawle

Looking forward to seeing the results of this. Basically the same mods I will do to mine before mapping next year.

It's gonna be a monster!

Re: My Classic mods in rediness for Simtek and Bob Rawle

Launch control is worth while if you are planning on drag launching, it retards the ignition to allow boost to build. Just holding down the throttle will not build boost.

This combined with setting the correct revs for the strip (note each drag strip has different grip levels) will ensure a fast launch. It can take a while setting up.

Mine was originally set at 5500rpm and 1.3 bar with Eagle F1 tyres on, as soon as I fitted 888's the revs had to be raised to 6000rpm. But once it is setup correctly...................wow.

On a Simtek, the option for antilag is setup with the launch control, but you dont need to set up either.

Re: My Classic mods in rediness for Simtek and Bob Rawle

Thanks JD... and all for input

The last part arrived yesterday VF28 and gets bolted on tomorrow... then off to Bob Rawle on the 29th with Bro Brumbrum... we will video the 'black art' if possible... if not then some stills

AIM 300 HP on performance map and will go for 'round town' on the second map

More interested in torque delivery than all out HP...

Be careful road mapping around Swindon, loads of roundabouts!

Re: My Classic mods in rediness for Simtek and Bob Rawle

yeah, as JD says. I don't fancy your chances in the saturday afternoon traffic espeically when Bob ups your boost and power and you have to brake hard on your 2 pots with three of us in the car

Re: My Classic mods in rediness for Simtek and Bob Rawle

personally i would recommend a dyno map which is finalised on the road.

you cannot create correct load conditions on the road.
