I went to Famoso Raceway's first test n' tune event of the year and it was really crowded, so only got a 4 runs in all day. Attached are a couple of the slips, with my best ET being 11.5 and best trap of 122.1. Mods are in sig, running 93 octane (mix of Chevron 91 pump and VP 100), Nitto 555R's, and full interior. Pretty obvious I still need some work on the launch.

Can't wait for the Airstrip event this coming weekend!

I thought you had mhp headers?

EkS

Good runs! Is that kleeman tune setup for 93? Do you always run a mix of 91 and 100 when doing daily driving?

xtyper

Thanks!

It's a 91 octane tune. I always mix in a few gallons of 100 octane when I go to the track just to be on the safe side and ensure full timing is run.

xtyper

No, despite having ordered a set they proved not to be the header for me at the time, so I ended up going with MBH again.

propain

Why not the header for you?


Whats going on with you west coast guys. You figure with you mods in +500 DA and 35% humidity you would be running better times. Is the track prep bad there?

Still a solid time but I figure you would be putting down very low 11's with those mods.

xtyper

Too loud and didn't like the fact that the motor mount heat shields needed to be removed.

I actually thought it was a pretty decent time considering the track location and poor 60ft. Should equate to 11.3's with a low 1.7x 60ft. Hopefully with more practice I can prove it. Also, test n' tune events don't help with all the waiting in line and high under-the-hood temps.

What is the best time anyone's run at this track with a Stage 2 C63? I think Jeremy from OE Tuning has run his car with similar mods at Famoso, but I don't recall what his best pass was. Maybe he'll chime in.

BAD430BENZ

why were they not the header for you

nevermind.....propain beat me to it

dodger63

You installed found they were to loud then removed them and put mbh on, petro mbh headers were just as loud as mhp.

Anyway that is a good number, not great but an improved 60' will yeild better results, but I'm sure that was the reason petro switched the larger primaries lost some low end torque, correct me if I'm wrong

BAD430BENZ

wait a minute...........

the MHP headers were too loud ? you are telling me that running the MBH headers with catless mids and x-pipe are not as loud as the MHP

these 2 videos i found sound pretty close....i think any header/catless mid combo is going to sound about the same with the oem exhaust . an axle-back exhaust fixes that issue

Thanks Mike.

Yeah, you're probably right about the bigger primaries on the MBH costing me a bit of torque down low, but I would think they make up for that with improved top end. I suppose only a back-to-back comparison test at the track/dyno would show for sure.

Since the MHP header trial Andy and I aren't on good terms due to a misunderstanding, but I would be willing to try his headers again if he ever gives me the chance, as I've gotten over the noise and MM heat shield concerns.

xtyper

You're right, but at the time of the initial MHP header install I was coming from a resonated MBH setup on my prior 2010 C63, so from there it was a big jump to full catless MHP in terms of noise. Also, the MBH system we installed instead was originally catted, but since then I've gotten over the whole noise thing and removed the cats to get the slight power gain. So now being used to the loudness and no longer having the MM heat shield concern, I wouldn't hesitate to give the MHP headers another try if I had a set laying around.

propain

You find the MBH headers to be quieter? Did you dyno compare the two? Im curious for my own purchase.

The time is decent. I didn't notice the 60ft. I wish one of you guys would come to the EC for a compare one day. The DA seems to be there for you guys are the tracks really that bad?

On the contrary though I believe its closer than I am thinking. Maybe I am being a little to critical. I remember Petro running 11.4's with the MBH headers at ATCO in +1000 DA with the same mods as you.

xtyper

This.

Come on Jim, cut the drag newb some slack...I've probably only got a total of 10 1/4mi passes to my name with this car. I'll get better and make you proud one day.

propain

I'm sorry. I didn't mean to come off bad. I realized it after I read your reply. I tend to take the human element out of the equation when looking at things like this.

You have more passes than me in 2012 already!

Keep at it.

BerBer63

elevation is 600ft+ too, but still the best track we have in Socal just 2 hours away

bhamg

Maybe I'm confusing you with someone else but weren't you the one who dyno-tested against/with an MHP-equipped C63 and the (curves)(power) were virtually identical? Apologies again if I'm mixed up as to who it was...

xtyper

Yes, that was me, but at the time the MHP car had 100 cell cats on. Since then he removed the cats and installed a custom x-pipe. He recently went back to the same dyno and made better power, so now I'm the one who's behind.

Merc63

I am itching to get to the track... Ill probably run close to the same.

PetroC63

Good job Eric.

Once you practice the launch, your ET's will fall. What I found worked best for me with the MBH set-up was to launch no higher than 1000 rpm. Before launching, gas it and hold the brake for a split second and if you time it right the car will slingshot out of the hole. It takes practice but when it's done right you will know, trust me.

What was the DA?

I was at MIR on Saturday, managed a best of 11.33 @ 125. It was my first time there and I really screwed up, no icing the intake, no race fuel and 3/4 tank of gas. Some real rookie mistakes but I had fun.

mthis

That's a good time for that set up u have.
How much gas u had in the tank

hotrod182

Its actually pretty solid numbers for this track. Unlike ATCO, you hardly see any record numbers generated at Famoso. You were trapping as high or higher than the 2012 GTR black edition. And the GTR guy knew how to drive, with this 11.06 ETs.

So the GTR was trapping 121mph compared to the 122-124mph recorded by GTRs at some other tracks.

The GT500 I ran did a 12.6 at 111mph
The SRT8 Challenger ran a 14.x at ~98mph.

Its almost always that way at Famoso, so you did well with a 11.5x. You are already nudging at the top 10 C63 ET listing on this forum, and did it full weight...so not shabby at all. Either way, had a blast.
Did some highway runs with a Blk Shelby, Mustang GT, and an E55 on the way back from the races to cap off the night!

xtyper

Thanks Hagi.

I started with only about 1/8 tank.

On my last couple runs I had some major shifting delay (power would cut out and jerk me forward, then suddenly the car would come alive again) on the 1-2 and 2-3 upshifts despite being in Sport mode with Traction control fully off. I really think this was due to fuel starvation since I could not repeat this incident on the way home doing some testing after a fill-up. Anyone else ever experience that at the strip?

xtyper

Thanks W.

And great job setting that 135i stock turbo record with the 11.25 @ 122.8 mph!!! Not sure I would have believed it had I not seen it with my own eyes. Since we didn't get a chance to run side-by-side at the track, I hope to get the opportunity this weekend at the airport.

dodger63

Yes
