Mojito at Road Atlanta

[7evin]

Hey Guys thanks for your support.

 

As many of you already know we were at Road Atlanta this weekend.

Friday during test and tune we were coming down the front stretch on our 4th lap

and the oil filter came loose and we dumped 4 qts of oil at 8500 rpms.

We finished Test and Tune on Friday after Loctiting the oil filter on w/o any other

problems.

Saturday morning we hit the track ready to run top 5 or maybe even set the RA Time Trial

Record. Well it wasn't in the cards. After the first lap Mojito would not stay in Vtech.

From all indications she appeared to be going into Limp mode. (I hate it when that happens :ack: )

We work feverishly between runs to resolve the issue. It appeared that the never failing

Honda ECM had failed. We searched every junk yard and dealership with in a 150 miles

trying to find a replacement, to no avail. Mandurath (Marc) found one on Ebay at a place

called HPC. My wife searched their web site and found the owners name and we gave him a call at home. He agreed to come in on Sunday morning open up and sell us an ECM.

I called Brian Anderson (the brains and talent that designed and builds the S2K) back to let him know that I got lucky and found an ECM, He was already on a plane with 3 ECM's

headed my way (broken ribs and all).... Wow... I could hardly believe it.

We picked him up from the airport

at 1:30 am and were back to the track before 3 am.

 

Sunday: We were up at 6:30 am and working on Mojito prepping her to do battle at 9.

 

We hit the track ready to put the hurt on some corvettes and porsches... We made

it one full lap with Vtech and she started doing the same thing.

We were still holding 12th position, But not where we wanted to be.

We decided to rewire the ECM supply voltage to the battery cut off switch so that

every other lap I could cut power to the ECM for 20 seconds and reset it.

20 seconds coasting with no power on a race track seems like an hour.

This didn't really help. It appears that the issue is with the oil pressure...

Not enough of it once the engine gets hot to keep the Vtech open.

 

Lap times:

Friday: 1:34.210

Saturday: 1:40.105

Sunday: 1:36.589

 

There were 3 7's represented at the event.

David Seybold in his smokin hot red and black Super Stalker. He came all the way from New Mexico to run with us.

 

The ever fast Paul Whittle in his silver bullet Super Stalker kept the heat on all weekend long.

We did not get much of a chance to hang out and talk because we were working our butts off to get the car right. But what we did I really enjoyed these guys were very cool people..... of course they own 7s.

 

We finished 8th overall and 6th in TTR (Time Trial Race)

 

Just thought i would bring you guys up to date.

 

Thanks again for all your support.

 

Cheers

I suspected oil pressure might be the cause of the problems. Is your oil pan modified? My S2KR is doing the same thing here and there. I haven't run codes on it yet but plan to very soon. It seems to happen more often as the car gets hotter. It starts around 180 deg though so it shouldn't be too hot to go into VTECH.

how did Paul and David do?

Sevnn: The service manual states that at 177 degrees (oil temp) you should have 35 PSI at idle. We are at 20. We run as high as 235 degrees on the track at full race temp.

The manual recommends changing the oil pump if less than 35 psi... The oil pump CAN be changed without pulling the front of the motor off. WestTex figured this one out.

Our oil pan is not modified yet. You might be able to get by with running a little heavier oil.

 

Slngsht: Paul ran 21st at 1:42.078 He said he normally runs in the 1:41 area. This is his home track. He is very smooth... makes me jealous.

David ran a 34th at 1:47.304 this was his first time on this track. Very impressive time for his first time on the track plus he was having a front end vibration issue.

 

I invited David to join our forum. We also flew the USA 7s banner. I intended to get pictures of all of us together but working on the car took priority over everything.

Don't feel bad Kevin, we tried everything in the book and then some. To bad it was the last run when we figured it out. You did fantastic considering that you were running at two thirds of the RPM range and half your normal HP. Michelle was a real trooper checking your list, picking up parts, and all with a smile. Love that girl!:7frog:
