On the Snetterton track day thread from Mondays event.

[Andrew aka Stuwy]

 

Hello,

 

After meeting you and having a chat with you, and watching you on track, would you mind if I make a suggestion?

 

 

Im all ears, im a complete novice to track driving and it wasnt until the afternoon I actually knew about the red and yellow cones so my lines were all completely wrong.

 

If im doing something wrong and you have advice then im happy to listen

 

 

Its not wrong, its impossible to do a track day wrong*

 

The cones wont be there on a race weekend, you need to learn how to read and drive a track. That can only be done with experience.

 

Take off ALL the wings, skirts, cannards, end fences, diffuser ect ect.. maybe even de-tune the car.

 

Get the cars geo set up how it needs to be, book into a track day and a session of driver training.

 

Then after driving the car all day, go home and analyse you on bored footage and how the car felt.

 

From there add a wing or diffuser (small changes) and book another track day with a session of driver training.

 

Go home compare your corner speeds/straight line speeds and how the car felt.

 

Then Add or take away change the bits you have added.

 

By jumping in the deep end with NO track experience you have no base line to build on.

Bit of an update, had an interesting couple of weeks assessing the damage and slowly making changes ready for the next track day

First up looking at what got cooked on the track day

Thats the spark plug cover for the bin

burnt a hole in the pipe between the airfilter and the turbo

melted the bottom of my air filter

also a bolt dropped down into the cambelt gear

blew a chunk out of the housing and cambelt


Repair time

Replace air filter with larger one since i will be also increasing the power

Installing turbo with 12.9 bolts and k nuts(special thanks to darren for them) to try and keep them together under heat


Temporary relocation of the air filter to get to some cool air




The obvious question is why not just use the drivers side inlet for the filter instead of the long journey through a hot engine bay, but for the moment that inlet is blocked by an oil cooler so until i move that over to the other side and have new oil lines up it will stay there.
I did strongly think about running the turbo inlet pipe straight through the bulkhead and have it in the car but since its noisy with the turbo behind my head I think it might be to loud with the airfilter sat behind the passenger seat, still tempted to try it.

Wowzers, lucky escape with your cam-belt, presumably it doesn't have a cover? The rest of it looks nice and easy to fix

The car didnt have any covers when i bought it, so im planning on going up a scrap yard next week and taking a full set off a random rover k series car, i cant imagine the crap man will want that much for a set

Also mini update, sat down this morning to start drawing up my aero modifications for the next stage, this is stuff i want done before the end of the month, the main aim is to vent both front and rear arches to reduce lift and also drag.



The front design will need adjusting slightly after having another look at the car this morning but the fundamentals are there.

So made a start on the back, before cutting looked at other competitors just to make sure they have been running something similar and there cut lines are similar and running in club class.


Saved 4kg off the weight of the car, so i think im about 705kg now, only another 25kg to go to meet my target,will need to change the diffuser mounting points to add some strength back into it as ive removed 5 mounting bolts but overall it should do the job well



next thing i need to do is find someone who can machine 5mm off each of my rear wheel spacers to allow the car to run lower without the tyres touching the outer arches

[Nev]

Haha, if you don't stop stripping bits off that car, you will only be left with the turbo (and no toaster) ! LOL. What front and rear neg camber is the car set up with Lee? Have you tried experimenting with it and what impressions did you get with different setups? And what front ARB and spring rates have you got front and rear ? In fact, whats your full geo setup please?!

2.7 deg front(remember i get more camber under bump so might end up reducing that down to 2.5deg as im not using the outer edge, 3.2 deg rear, again looking at it, i might reduce slightly as the the outer edges arnt being used.

 

Im running a pilbeam arb on the stiffest setting, im currently running 700lb front and 1150lb rear, i did plan to change back to 900lb rears and see what my roll is like on track, though looking at some of the pictures from snetterton i can still see a bit of roll in the chassis so i might keep the rear springs as they are and see what its like at brands.

 

I never had traction issues, never had any understeer or oversteer with this setup once i had a few laps under my belt, but at the moment i havent really pushed the car to the limit so at that point i will know what the balance is like and change rates accordingly

[Nev]

Gosh, that's quite an aggressive setup, can't be fun on the road.

only turned the front up to that on track, I run it at around 1.7 on the road, the rears im going to make some new shims this week to I can reduce the camber for the road.

 

The car is still along way from being dialed in and neither am I, so we should both go faster every time we get on track, plus the car and myself need to go on a diet, there is a good 50kg to be removed combined yet.

 

On the road when its 650kg it feels pretty quick, not NEV million horsepower quick, but not slow, i would imagine when its up to about 340bhp and around 500bhp per ton it will chase most things down up to 130mph

[Nev]

I found 0.4 degrees of neg camber on the front suited my car best for fast road. I found that when I had more negative camber that I couldn't rely on the front to dig in with certainty (which clearly you need when driving on unknown roads).

 

You car sounds amazingly light, it must be quite different to mine in "feel".

 

Keep spannering and keep us up to date mate 

[Matthew Bentley Racing Ltd]

Would need to check my setup sheets to be 100% but Mikes car ran 3.75deg front and 4deg neg rear camber and Jamies TA car we ran closer to 4.0deg front and 4.75deg rear.

yeh, both of them have said to me they run alot more camber, the interesting bit is when you look at my tyres there is a good 35mm of tyre on the outer edge front and rear that isnt being used, I always thought you should look at camber firstly by trying to make sure all of the tyre is being used and once your in the ball park then look at tyre temps.

 

Is there a reason that you run so much more camber, is it because im not pushing hard enough in the corners to get the roll which will then use more of the contact patch?

[Matthew Bentley Racing Ltd]

I would look at tyre temps last. We run that much camber for two reasons, one they need that much as the tyre wear is even, and secondly it better to be on the side of too much camber than not enough. 

 

I would say yes you probably aren't using the whole tyre surface because it was your first time out and corner loading isn't where it could potentially end up.

well i know the apex speeds and the turn in points i need to emulate around brands for a 51s lap, so thats what im going to aim for, whether i or the car is that fast i have no idea, but i will be sending the car through at the speed needed so It will either be a win or bin situation!

Lee, for your and everyone else's sakes, for god's sake don't do that!!!!!!!! How do you know that the track conditions on the day, your tyres, your setup, your driving etc, etc, etc will allow you those specific speeds??? Just get comfortable in the car on whatever day you do and take it from there. Setting yourself a target this early on in your development phase will most likely end in tears.... A 51 second lap isn't hanging around.

yes it is, 51 sec's is gay!

A 51 second lap is quick round Brands Indy in anybody normal's book so don't let Simon wind you up. Lee, listen to Jamie FFS-It has taken a long time in a known car to get to those times, not straight out in an unknown car with a relative rookie behind the wheel.

Ha, I should of known you'd bloody say that!! If 51 seconds is so gay, then why were you doing those sort of times in LOT class C racing?? At least I seem to remember it was those sort of times..........

 

Joking aside, I don't reckon a 51 is gay. Yes, I dipped into the 49's in my car in 2010 in testing on 888's, (without the sequential) but during the actual Time Attack event couldn't get anywhere near that because of the different conditions, circumstances etc. And yes, I know you've been round in a 47 something in an Elise on slicks.

 

Anyway, very much looking forward to seeing what we can get the car round in once it's back together. 45 ish do you reckon?? Obviously not with me driving. I'm far to gay:)

I got down to a 51 in my Honda Elise but it took time to build up and I mean weeks/months. FFS dont just go for it, it WILL end in tears
