time attack are doing a little write up on each class before the final race at snetterton

http://www.timeattack.co.uk/index.ph...nge-rwd-final/

 

Congratulations mate! I think i'm rite in saying this is your first season of competing isn't it so well done, you must be well chuffed with what you've achieved and the possibility of winning your class! Good luck with the last race and congrats again!

 

thank you mate,

yes it is my first year

to say i am chuffed is an understatement!!

looking forward to the final race

 

Fantastic stuff Ronnie

Waiting for you to PM me your address so I can post these high-res pics from Cadwell

 

thanks mate.

i'll pm you my address right now

 

Well dont mate

 

I'll get the CD posted today

 

thanks mate you still not coming next week?



thanks mate, love you x

 

nice one ronnie

 

hey ronnie, you thought about adding more downforce to your car in the future, i know you probably dont want to add more power for fear of reliability but just just thinking if you want to win maybe next year then is it something you have thought about.

Just alot of the japstuff have splitters, diffusers, big wings and canards, and eg matt webb has full double wishbones alloy suspension front and rear aswell.

Or dont you see yourself wanting to push to that level?

 

I'd love to go as mad as I could with everything mate, it's just the money side that holds me back

I know everyone is on a budget. I am on a tight budget so it's all down to money really

But hopefully I'll have some more sponsorship for next year which would enable me to put the money in to some testing etc

 

Go on ronnie my son put the ole mota on top spot son you deserve it ;0-)

 

Well done beloved x

 

Well done Ron you & the guys have a fantastic job this year a big pat on the back to you all

cool, fair enough, you can easily and cheaply make your own to help with downforce.

using thin ali which is cheap, light and bendy is your best bet, bend a couple of canards for each side of the bumper and bolt on a piece of plywood painted black will cover you for a splitter.

that was you will have much more front end grip which will help on turn in.

then since id imagine you would want to keep your whale tail you could increase the size of the gurney lip on it to provide a bit more downforce.

there is the option of making a diffuser but to be honest unless your car sits alot closer to the floor i wouldnt say its worth it.

Just thinking out loud to try and speed you up the cheapest way, downforce realistically is the next step up for you.

as you cant really compete in the suspension department, power is to costly and cossies are heavy restricted in terms of tire widths(rx7s can run up to 335mm wide tires or 315mm on stock arches if required)


How do you find the balance of the car currently,

in low speed corner entry/exit
in high speed corner entry/exit

sorry if its loads of random questions but im just thinking for the future

 

i never thought about making my own canards to be honest, but the ali sounds like a good idea

i have an escos lower splitter that i have just fitted and i will extend off of that under the car as an undertray.

can rx7's have tyres that wide? blimey, i've only got 225's

car feels fine now in high speed corners

low speed is under steery.

questions are good mate, no need to apologise.

thanks

 

Surely if its a case of more downforce then simply have beefy as a passenger

seriousley tho ron nice one,well done for season one you and ya crew should be well proud good luck with the final race

what/where exactly is the restriction on a 3dr for putting wider rubber on the back?

 

jesus!! my rx7 comes with 235s on the front from factory and everyone complains thats not enough rubber on the front, me included!!

ill be going over 285s front and rear by xmas on stock arches to help balance the car out

since your high speed seems to be fine you need to be careful with your balance, if your going to add canards, you need to run a decent angle with them to make up for your lack of tyre on the front, this will help with your lower speed understeer, but then id advice you extend the wing on the rear of the car, the rs500 mini gurney does help at high speed but if you bolt on a extension to that in ali(curved of course) this will increase your lower speed downforce level and balance out the canards.

you should be able to get more tyre on that id imagine, you might need to work on the arches a bit but your gonna need more tyre to compete, especially at the lower speed corners where mechanical grip is more important.

if your struggling with the wider tyres rubbing on the outside of your arches, what are the insides like, you have to remember its not a daily driver or a drift car so you dont need to worry really what its like on full lock(unless your sideways everywhere, in which case suspension needs work)

the way to get bigger tyres is to increase the width of the wheels but offset that with a high ET, ie if your running 8inch et30 wheels, move to 9inch et42 which means your wheels 'stick' out the same as the 8inch but you have big tyres on there.

good thinking on the splitter, you want it running back to at least the sump, the further you go back the better, if you can extend it to the gearbox then thats ideal.

if you want some pics of my canards i can stick them up for you for ideas.

 

or you can just stick to the body shape that won every touring car championship on the planet worth winning as standard.
you fuck about attempting to add Aero without a decent wind tunnel or computer programm and you end up aggravating the issues of running on shitty tyres that dont do even std roadcars much in the way of favours !
Aero is the very last thing you need to conern yourself with on a control tyre, work your suspension correctly first and you will see much greater gains .

 

true, but back then what did it have to compete with, there was nothing really thrat put out the 500bhp+ of the 3doors in competition....look what happened when the skyline gtr came along.....more grip so dusted the rs500s....plus they were running slicks which gave them much more grip over what he has.

Just thinking that since he is limited on tyre size compared to others(his main competitor has a smaller car with much wider tyres all around) the only other option i can think of is aero, he cant get a more advanced suspension setup neither than a well prepped rx7....hence what else is he left with.

if you were him competing against a car that beats you in everyway apart from possible aero, what would you do, try to be the better driver?

not having a go as i know you have much more knowledge that me so it would be great if you can expand your ideas

 

I meant that he has a LONG way to go IMO before that needs consideration , working the tyres to the best of their availablility is more to do with mechanical grip and spring control , sure a slippery shape helps but then the 3dr has that in its favour already .Time attack is all about a 1 lap , getting that right at the optimum time and temps is all about the tyre ,and not a very good one at that so go practice the set up to each circuit and optimisie what you have ,get it off those 18" rims for a start and drop the car over the wheels ,re-valveable dampers and optimise the geometry etc...
