Cams and Pullies


VEMS S13 Loom adapter - Money shot ;)


Graham and Nismo Pete have been busy with my car at DCMS :notworthy

Pics speak for themselves 





This EGT Probe isnt the VEMS one, just for plugging the hole drilled for the time being.






The Prototype manifold needed quite a lot of core rotation so the actuator had to be adjusted













I believe the engine is now in, and should be fine to be at APT on Sat 3rd March
Thanks Graham @DCMS of Burnley

Car wouldnt start when built, suspected it was the Alarm.
Massive [size=24]THANKS[/size] to Gary for sorting it, never seen an alarm ripped out so fast !!!!

The removed offending wiring.


Phatbob probing ...


first plug-in of VEMS


Modified CAS, this may change design after the initial testing/timing issues this weekend

Today Phatbob swapped the 4 hole CAS disk for a 24 hole one and solved the 1 hiccup in the plug and play system - no pics as I wasnt there, however I heard the car running and idleing on the phone.

Yes, thats installed and running :D :D

Got an update, from APT in Norwich, my Tuners, via Rob :D
Theres no Cat, just a full 3" bore exhaust/drainpipe.
Quote from: [email]rob@vems.co.uk[/email]
Just been talking with Gary , he's got the car to idle on the SARD 1000cc injectors with the following gas analyser readings:
270 hc's
1.0 co
1.0 o2
1.00 lambda
14.4 co2

I'm rather pleased about this as it goes towards proving that our injector control code is as good as we've always said it was!

Looking forward to seeing the power figures now.

Rob

Well, its spent all day on the dyno ...  still some tweaking but my Tuner is VERY happy with the VEMS.

Quote from: Gary@APT
heres the best graph may be a little more to squeeze with a more stable boost,but making good power for spec!!


you can see how boost is a little unstable but not bad for a low pressure actuator


overall the vems looks to be the bollocks,we are only running the 1000cc sard's to only 58% but idle control is amazing

i reckon kev it will be great on track look how long the torque spead is:thumbs:

Well Time Attack round 1 was at weekend.
I'm happy, got 8th with a cracked manifold, 6 of the cars that beat me had over 500bhp, and was 0.35s of 6th, and the first RWD car.

Next round I'll have more front aero parts and will have number 4 runner welded to the manifold flange again .....

Hi, car looks excellent & obviously is doing the bizzo! I have a vested interest in the engine specifically as I'm in the process of building a CA18DET for my Relaint Scimitar SS1 Ti (to replace the CA18ET thats already in there!). What spec is your engine / turbo / ancillaries as you are getting pretty much bang on the power I'm after from mine. I'm building the base engine at the moment (wisecos, pauter rods etc...). I'm in a quandy as to ems at the moment as the ET is running Emerald M3D but I'm also building a bike which I need an ECU for which is likely to be VEMS at the moment but it could easily swap around......

will drop him a line and see if he would like to takle a vems powered Rover v8. A bit of a treck for me but if your experieces are anything to go buy will be worth it,

Do you mind if i ask how much he charged and who you delat with.

Regards and thanks agriv8

Well I also had some other work done, and he is helping me out a little too to get the car to race spec.

I believe he has quoted around £500 for other mapping jobs similar to mine, thats also similar to what he charges for other standalone ECU's

rob pasted me the vids so I gave em a looksy, good lines with some honest mistakes, but you commented them all yourself, so you know which is a good thing :)

to much curb makes the car unstable and is not good, on some tracks you can't hit the curbs at all in some turns, while on wet you DONT won't to hit any curbs so thats a tip to note.

when letting the car out you wanna pretty much drop it either on curb all the way out if flat and try, or on exactly the white line if rainy or no curb, no more no less.


now when it comes to brakeing, stay 0.5cm from white line as if you hit it with a wheelset you will have uneven traction and get a unstable car under brakeing.

with a whole lot laps more you will be able to do this perfect I think, and will also take the experience to other tracks, new tracks is always hard, but if you have a good base it sure helps!

what setup are you running on the car? suspension? pads? wheel psi? wheels? tires? camber front&rear, toe in front, caster etc?

must say it really appears to have good turnin on the video, and a good even power curve. but everything can be improved! as an example here on our local tracks we can race with uneven psi/camber for  getting the last few nano seconds ;) (only for small courses usually)

what pads are you running on the k-sport, and have you measured caliper flex? a tip can be to have them drilled with a few extra cross braces.

regards Anders

p.s. you really do have a hole saw fetish :D what did you weigh in at?

Cheers Anders, I have done much tidier laps before (with less power)
http://media.sxoc.com/contributors/sm/Donnington%20April%2006/SM's%20Flying%20Lap%20of%20Donnington%20national%20April%2006.wmv

Car has coilovers with springs that are a touch hard 10kg/mm fronts and 8kg/mm rears, they are my sponsors own brand but come out of the same factory as Apexi N1's, and look remarkably alike ;)
Uprated anti-roll bars, medium front (to combat understeer) and hard rear.
Running around 32psi on DJ01's, probably need to be a little lower, the Team will have a tyre temp gauge by the next round to help tune the pressures.
DS2500 pads.
I'm running as much camber as I can on the front, need some longer lower arms to get any more - just under -2 degrees, 7.5 castor and 2mm toe in. Rear is more like -1.5 camber, 2mm toe in. Wheels are reasonable light 17x8's

I havent a clue what it weighs as yet, I would guess around 1200. I Broke the rear screen the day before the race and had to use a spare boot, for the next round I'll have a plastic rear screen :D
