So you mean like a class where people bring what ever they want to the track and then run it. . . . . .. so like a RWYB?
That and the fact that 99% of the time man with the biggest cheque book wins will see it getting pretty boring pretty quick
great in concept but to produce a concept competitive class is going to take more than a one line facebook status

Thought I'd post here too.
"Really wish there was a HEADS UP race class in the UK..... altereds, dragsters, slingshots, doorslammers, turbos, supercharged, nitrous, anything goes. Just drag racing! No sand bagging."
That would be cool. Bring back pro comp!!

Comp Elim or Top doorslammer please !!
Our little V6 is fed up of bracket racing & to little to be allowed into Pro Mod ........
Just drop a VK in it chap... You know it makes sense.. Our little V6 is fed up of bracket racing & to little to be allowed into Pro Mod ........
In terms of full blown, all out, heads up racing, yes I can definitely see some potential there, but there needs to be some level of weight/HP/cost control..
Top Sportsman seems to be the right sort of direction (having a had a quick nose at the rules) but I don't know enough to make too wide a comment...
Top doorslammer would obviously rule out the pointier cars which is fine by me, but the 6.0 cut off would be nice to lower a bit, maybe 5.90? It's still not the ultimate answer though because if it took off and money was on offer, someone could come along with an uber light car, screw blown hemi and spares for Africa and pretty much sweep up if they were on the ball. As for a true anything goes class, what would stop a top fuel dragster entering and just clicking it off shortly after mid track or something and collecting the spoils?

Not at all, look up a class called 7.0 Pro in states, great racing. That and the fact that 99% of the time man with the biggest cheque book wins will see it getting pretty boring pretty quick

Not the case, if rules were written right then most money should mean sh*t. There would need to be an ET index cut off, say 7.0 or 6.90 or whatever.
Aware it will take more than a facebook status too, but I posted for opinions

Thats the point let the dragsters in but as mentioned it would take some clever rules using weight/engine/fuel to sort it to be fair. For me simple as, they cant race in this class and wouldnt anyway but i get your point, someone could in theroy wipe the floor but great, makes the rest get faster,
this is my point, how many racers have been racing with the same ET since forever, where is the progression? the 'try this' attitude, its simply bolt this to that and run the same
now I am not for one minute knocking dial in classes they have an important place in Uk racing but heads up IS drag racing, its the get faster or go home
and think of the cars that could run in it? loads
there needs to be a class under FIA racing thats heads up but with sensible and very well thought out rules and it would take off
wicked fish said:
i bet john spuffard/gordon smith/dave wilson would all like that too!!
especialy if there was prise money
Like i say, its only an idea, they can enter if it ever happened but again there would need to be an ET cut off but fastest and slowest especialy if there was prise money
Whole idea is aimed more at 'Sportsman' racers, though I hate that term,
take super mod, heads up, good racing, job done,
this idea but race altereds, dragsters, slingshots, door cars, dont really care, all heads up

I dont no alot but i think the problem is putting a cut off as it hinders it having 7.00 cut off still would end up as an unintenstional et class there would be cars that run quicker than 7.00 and as said just clicking off at 1000ft to stop a break out like said it would need other restriction with no cut off to be a true heads up class
