One last go at Santa Pod
Hi guys,
well I've been to Santa Pod about 10 times this year now. I only planned to go once but each time I kept thinking I could do better and I had to go back to try. My first attempts at the start of the year showed me I didn't know how the heck to launch the car and saw me getting 14 seconds. Later I managed to figure a way to move off by holding the car on the brake and engaging the accelerator just a bit to engage the clutch of the DCT. Brake boosting isn't possible. I managed to trap over 110 mph before adding meth injection and then managed just under 12.5 seconds ET with the meth at 117 mph. Later I started using a back end flash to better use meth injection and ethanol added to my fuel but I always found that the flash never quite worked with the DCT transmission. The shifts felt off and laggy. The car really lurched. It was like changing gear in a manual and not quite fully getting off the clutch. So for this reason I got a custom flash done by Trebila. Some people use Wedge or Spxx or other. Anyway in the recent tests at home the shifts felt really good and the car felt fast so I had to hit the strip again. I went running 25% ethanol in the fuel tank and meth+water at 60:40 to suppress some timing pulls I was getting on cylinder 2. I've tried changing the spark plug and coil pack but I can't get rid of this issue. It's probably carbon build up in the cylinder, a bad injector or false knock. Anyway timing was pretty food on my runs with just cylinder 2 a little behind. Running a 50 meth adder I managed to break my previous best trap speed of 117.95mph with 118.06mph but my time was a poor 12.9 secs due to a near 2.5 sec 60ft time I was happy that the car had potential. However my second run was 13 seconds and 117mph. The next 4 of 5 runs also saw 2.4 sec 60ft times killing my ETs. Then on my last run of the day I nailed a good 60ft time of 2.1410 secs. I had the car on the absolute limit of grip without spinning too much and cruised to a 12.2179sec@120.59 mph. That's M4 trap speed right there. I'm sure if I had better tyres I could break into 11's. Anyway very chuffed and probably going to leave Santa Pod until next year now. But you never know Video, time slip, log to follow...

That's a great time! I'm planning on going this Sunday for the last rwyb of the year. I've not run the 335i before so it'll be interesting

p.s. I always felt my car had more than the 117 it was achieving. Firstly because of the aweful traction off the line and secondly because my DCT was never working quite right. The service I had a few months ago also helped. My brother beat me to the line twice in those videos but my ETs are lower each time.

Hey Jack,
Trebila definitely has the car dialled into perform with your DCT gearbox, well worth the investment! Consistently over 120 that's getting serious Like you say, stick some drag radials on and you will be in the 11’s ! Well Done bud I will have to practice brake boost for next time!

the guys in the states get some seriously good times off the line with the brake boosting in 2nd on steptronic. There's an enourmous bonfire there soon. You should take the kids

Just looking at the log! You're pushing that LPFP I see you are short shifting and not a full throttle in 1st and 2nd too much wheel spin? Love to see what you could do with some VP109 and some 275 nitto nt05r on the rear!
Or is it time to invest in a stage 1 pump???? Might be a visit to Shrewsbury again

Yes, I saw that...unfortunately we have other plans...it may have been a different story if the inlets would have arrived and David had worked his magic

I think you're getting into territory where you desperately need a LSD!
It'll transform your launch and first 60ft.

TBH I don't think I'd bother with a LSD. Better tyres would be a more economical way to go. I think I'll get some Toyo R888 next year.
I had to really modulate the throttle in 1st and 2nd. That's how the low 60ft time was achieved. Before each run I did a small wheel spin to heat the tyres. In 1st gear I can just go full throttle and the wheels spin immediately, the car barely moving. I didn't hold it against the brake as I don't want to wear them any faster. On the lpfp I think maybe the flash just isn't quite able to handle rapid changes in demand for fueling, with ethanol and meth and water injecttion and rapidly varying trims. I may play with the fuel scalar a bit.(See the trims are 30's and 20's in 1st and 2nd, but 0 in 4th and 5th!) I also don't know if standard pumps cope well with low levels. Do they have the venturi to help maintain flow when acceleration may throw the fuel to the back? Anyway an upgrade will happen at some time. For me this puts the run into perspective

haha yeah
He was a nice chap. I had a chat with him. His back window was full of cuddly toys so I wouldn't say he's too hard core.

Definitely no LSD is needed. Good times but you can definitely do better.
As you say, work on that 60ft and get your self some better tyres. No LSD was required recently for an N54 to break into the 10s... so Tyres it is. You should definitely not be wasting any time launching in 1st. Why not just limit boost in second so you can push it to redline? Or use the JB4 to limit it in lower rpms and maintain a higher boost in higher rpms in second gear? |

The Xdives are great of the line but the added weight of the 4WD means they suffer on the trap speed.

Just think how this guy in the BMW felt! "I'll just go out and take it easy. What's the worst that could happen, right!?" Hope he had cover

I'll definitely get insurance for a full track day. But for 30mins on a taster session? Rockingham said they have never had a single incident on a taster.
But when i go to a full day then insurance is definitely something i'll be getting. As like you say, even if i'm driving ok, it could be someone else driving like an idiot. |
