Did you do the engine calibration for that? (is there a torque curve to go with?)

If you did the cal, that is very impressive nice and smooth (ignoring the numbers).

 

Depending on the AFR and response, you might want to lob a little more fuel in below 2.5K, and perhaps a tiny hint of ign advance.

yes I did map it myself, on the road with no det cans or proper afr logging(just looking at the wideband under throttle), its very roughly mapped at the moment and theres loads of driveability mapping that needs to be done, but i will get help with that with someone more experienced.

 

its fairly laggy setup as its not really designed around a stock engine, more the forged engine im building so 25psi+ and 8000rpm capacity, but since ive got a close ratio box it will allow me to keep it in boost on track.

 

I might turn the boost up a little more to help with the top end as the dyno guy said you need to set the cams and increase the boost if you want more power(dont actually know what the cams are set to, just that they dont touch the pistons!)

Fair play... if only I had the time and a more understanding girlfriend Admire your practical ability

Have you been watching made in Chelsea or the only way is Essex or some such bollox? ...next you will be calling your car your "whip" and describing it as "reem"

[darronwall]

why are you still considering doing a public session at a ta event to test your car??it is comparible to going for a day out with a sunshine bus load

just come to croft will you

You dont really need much time to learn how to map, im completely self taught from scratch, had no lessons for spoke to anyone, just jump in the car and make adjustments and then watch the wideband, that will teach you 50% of mapping straight away, its just simple maths and physics.

 

My partner isnt in to cars and I dont have alot of free time, its just making sure you allocate a little bit of time each week to work on the car, you dont get alot done but over the weeks that time adds up.

All depends, im making some carbon fibre wing uprights today, if they come out of the mould alright then I might well go, im not looking for lap times, more just to feel the car on the track again and get the scruits to have a quick look at it.

 

Will you stop going on about croft, i will get there eventually, I might be getting made redundant in the next couple of weeks so dont have loads of money I can spare with 2 young children and a house.

Cheers buddy, always look to yourself for inspiration, if you dont actual try things out yourself rather than following the herd then nothing would ever get done.

 

If it proves to be reliable then its an option for us lotus guys who want 230bhp+ but dont want to have to pay £10k for a honda conversion.

im at oulton park at the weekend so if anyone is going and you see me, please come say hello

pops flames well

[turbotoaster]

thought these 2 pics might help show where i am aerodynamically.

 

first is a stationary shot, the spiltter is 70mm from the ground and the skirts are 60mm from the ground, the diffuser has been trimmed on the moving shot so ignore that.

 

 

this is with 700/900lb spring setup and im accelerating at around 90-95mph

 

so when im running full power i might need to up the spring rate if its touching at 110mph+

[Nev]

The lack of gap under the front arches is clearly noticeable when moving. I'd love to have even 1/2 the frontal down force you have

[turbotoaster]

Well your car easily has the potential to match it, or even exceed it with the vx from clam having a pretty square face

 

Just as a reference point on how the car is now, on my first clear lap(so basically 2nd ever lap in the car in its current setup and first time at oulton) i was 1.5secs faster than jimmys best lap in his yellow vx220 and on the next lap i was predicted to be 3.5secs quicker but a red flag came out, this is with the same power, my car and me combined being about 150kg lighter though, i think with more laps it would be 5.5seconds quicker than jimmys with the same power.

 

Im not knocking jimmy or anything like that, just thought it would be a nice comparison as we are the same power at this point, watching his video he is about 5mph quicker than me down the straights.

 

now compared to mike from 2013 he was running on the international circuit so not really a direct comparison, with that in mind he will have a little bit of the lap where he has the potential for a high top speed hence bringing his average lap time speed a little higher, he averaged 84.6mph, my first lap was 83.7mph and if i had got the 1.38.2 it predicted then that would mean i averaged around 85mph so matching his time assuming i dont make a mistake.

 

I think mike was running around 350bhp then and 800kg compared to my 710kg and 250bhp

[G-Bob]

good to hear you are finally getting some seat time. 

 

From reading all the reports etc.  it seems that clear laps are a bit of a rare thing in time attack and the skill seems to be in finding the space and making sure you don't get caught in traffic.  Apparently that's a bit of a skill in itself.

Are you comparing to Jjj in season 1 or 2?

[Nev]

Wonderful news, I had no idea your first session went so well, it just goes to show what sound principles, genuine vision and determination can achieve. I take my hat off to you. I am hoping you may even get a quiet apology from a few of the previously nasty (and mainly uninformed fukwits) who have taken the usual negative stance to anything "not out of a box" or bought from Elise Parts. But I doubt it; they will just hide away and wait for the next easy target Good on you Lee, I hope you get to refine and tweak it now over the next year. Once you do, please run some circles round the VX drivers at next years National, or burn them alive with your exhaust as you overtake them on the corners!

I compared to 2011 for jimmy as that was the last time he was there, I also checked through all his runs for the day and watched his video to check for any traffic and it was clear.

 

I don't have any footage of mikes but I went through all this laps for the day to make sure he hadn't run faster earlier in the day and all his laps are within 1 second of each other so its a pretty good assumption he didn't hit traffic.

 

Since 2013 was the last year of running I assumed his was reaching the 'ultimate spec'

 

Don't get me wrong its not super quick at all at the moment, im leaving 70-80bhp on the table which the current engine and another 50bhp ontop of that for the forged lump, and I was nowhere near as hard on the brakes as I should be so there is plenty of time to come from it, at the moment im 5secs off the TA rwd lap record around there owned by Jamie Willson so I have a lot of work to do.

 

My aim for the car is to take that record and while there is still a lot of work to do from the car and my driving its going in the right direction.

 

I would love to be invited to national day, be great to see how it compares to a vx220 with reduced weight, its a bit slow in a straight line but would be fun to see what its like in the corners/braking

[The Batman]

Ah ok dude, in 2011 he had to run Pirelli pzero tyres and was running 250bhp so not a direct comparison as you are running semi slicks! Ooo Jamie and scuffers would not be happy if you took that record! So go for it dude!!! Stop saying you're under powered! even if you run 250bhp you are still only 700kg!!! And book the national mate

Well its a bit slow compared to stage 4 turbo guys I would imagine, plus ive had it up to 1.7bar on the road the other night, the torque at that boost is immense!

 

That would make sense on why I was so much quicker than Jimmy even when taking it pretty easy and he was 5mph faster down the straights than me.

 

There is so much time left in the car, watched a video of maidstones lotus cup car and im 11mph slower through turn 1 and 11mph slower down the straights so its going to be interesting how fast it can go with practice and more setup time, haven't even played with camber as its still setup as 1.5/2.5 degrees for road use.

 

I think a full day testing at oulton will bring out its true potential

 

When is the national and where is it? if its at croft it would be cool for mike to drive my car to see how it compares to his.

It's at snet 300 so you can turn the boost up and play with the stage 4 tubbies! It does really show how much potential the car has, considering you have next to no driving experience on track in the car. Get a proper lap timer though, performance box etc
