I think I have the 2nd fastest UK M113K car, the fastest being an E55 wagon that ran 11.16s, built by MSL in Birmingham, with close partnership with Eurocharged. Lots of mods, and on CLK wheels and drag radials.
Very nice improvement over the span of a year; congrats!
What's next on your mod list?
Thanks. In fact, it's over 5 months.
I have a 74mm pulley waiting to install.
Then as one project, I'll install water:meth, 82mm TB, replace a bunch of gaskets. And maybe injectors. And definitely 16" CLKs with drag radials. That should hopefully be enough for 10s.
82mm throttle body
77mm SC pulley
550cc injectors
Water:Meth injection
Mickey Thompson ET Streets on 16" CLKs
Bring on the 10's.
You will like the Mickeys and the CLK wheels are very light. Certainly looks like 10's are in sight. Probably will still need good air. My meth set up never really helped w/ ET. Trunk tank did w/ IAT usually 110-120 F max. Good luck !!
Little update.
Mods over winter.

The WMI is not doing anything to IATs. There are leaks, one was found at the solenoid, another near the pump. Those were both fixed, but still IATs not helped. I haven't been able to check if there's a leak around the nozzle itself, will need further investigation. It may be that meth in this set up does nothing to IATs, but have spoken to several people with exact same set up and they all see significant reduction in IATs. Will see how it goes. Anyway.
First day out this year:
11.35 at 122mph. 1.6 60ft
Can't remember ambient
DA was 950ft and it was warmish, slight headwind
Starting IAT 104F, max 158F
Next day out
11.17 at 125mph, 1.64s 60ft
Ambient 57F
DA -65ft, no wind
Starting IAT 68F, max 158F
IATs are ridiculous, as is the 68mm pulley lol. Highest boost I saw on OBD scanner was 15.7psi.
So still needs more cooling, better weather.
Either a little more conservative pulley (72-74mm) or just shift gears a little earlier.
High 10s is there in the right weather, without changing anything at all though.
I find my DO10 keeps me temps about the starting temps on a run. During wheel spin though the meth wont spray - boost is cut so pump doesn't run. Can be a bit of a pain in that regard.
Hey bud, nice times! But you DEFINITELY have something up with your WMI. I'm not running as aggressively as you, only a 77MM but with addition of LTHs and WMI I went from 160 1/4 mile end temps to solid 95 for the whole run (#3 pre SC, #7 post IC). Other cooling is just the frozen boost Hx and a CWA50 in place of the stock pump. I would definitely trouble shoot that. I don't know what you've already done but first I would check that you have any flow at all by disconnecting the furthest down stream point, and manually initiating your meth system some how. I do it by jumpering around the relay I used. If you need to you can disconnect the outlet side of the solinoid and run a length of tube out of the car, manually initiate it and put your finger on the end of the tube, make sure it is building good pressure.
I had the stupid low profile DO nozzle holder fail on me, I think they don't do well in the heat because I helped another guy out that had the same problem. I noticed my temps started getting a little worse so I took a $10 borescope from amazon and checked the nozzle that way. I started the car to an idle with the bore-scope down at the nozzle and jumpered the relay for justtt a second. I recorded it:
What I ended up doing is taping the bore-scope to a pick, then I used the pick to push on the retaining mechanism while I removed the hose. After trying new hose I found that it was actually the connection, I could just pull the hoses out, the nozzle holder quick connect was no biting into the hoses well.
So, because I didn't want to pull the supercharger to deal with this nonsense, I ended up putting red RTV around the hose. It has been holding strong for about 4 months and 3 trips to the drag strip so far.
Anyways, hope that helps, I'm sure once you get your system issue found you will have no trouble being in the 10s!
Also, just to add, none of that was easy haha, it was a frustrating pain in the *** using the bore-scope to see where the hose was and what not. But I'm sure overall it was much easier than pulling the SC.

Wow a 68mm pulley with no BWK, I'm guessing your boost is fine for that pulley? Ie: you not experiencing any belt slip? Who even makes/sells the 68mm clutched pulley
