I can only speculate... and it doesn't matter really, key thing is to dig out and get the car sorted

travisjb · 03-13-2010, 09:20 PM

Turned a 1:04.75 today at Firebird West. I may have done better than that - not sure - I only had someone timing me for a couple laps during 1 one of 5 sessions, so pretty sure he didn't get my best. In any event, course records are below. I am a few seconds off the pace for the course record for my "TTS" class. My car is still 300 pounds over weight (or underpowered) relative to my class limit, so I'm running a lot more like a "TTA" car right now. I also think I can pick up a few tenths with SRM - for some reasons my brass balls factor goes up when I use it. I'm overall happy with the result. Today was just a Porsche Club DE, will do this "for real" next weekend when the people you see listed below will all be lined up to compete!

Will post more thoughts later tonight on remaining mechanical issues to be sorted. Sorry, no vid today.

thanks but not just yet, Mr Zless... the 104 target applies to Phoenix Intl Raceway... add 4-6 seconds for typical spread between the two... For a track record, I likely still have 4-6 seconds to make up at PIR and 2-3 seconds at Firebird.... very long journey ahead!

Big stuff

Fuel starvation... still need to fix this... haven't made any progress and it is going to be needed to drop a couple tenths off my times
Brake issue... I had the "ICE EFFECT" big time today and it was embarrassing... the chief driving instructor thought I was just being an idiot when I slowly grinded to a halt half way through a carousel... I have a new theory about what is going on that I will explain on the thread Chrisslicks started Braking problem - malfunctioning ABS... I'm going to proceed with more brake cooling, but that's *NOT* the root cause, I'm fairly certain
ECU issue... I want my SRM back! could be as simple as reprogramming the computer... it is new and the dealer didn't have time to program it... could also be we have another short, blown circuit or disconnect somewhere... the three center gauges are not working... I haven't even checked the fuses yet, so that's the first order of business
Rear diff cooler setup

Smaller stuff / lower priority

Connect transponder, reconnect traqmate/chasecam
Splitter ver 2... need to revisit the fasteners - they are being sheared off whenever I scrap the track - will post more on this below
Fluids... gear oil, motor oil
Setup... I'm thinking about -3.0/-2.5deg camber, neutral toe front, -1/8 toe rear, and 5.0deg caster front...
Stiffer springs... I'm using 10/12k springs now and I'd like it to be stiffer yet... won't happen in 2010, but eventually something like these Moton 3 Way Adjustable Nissan Motorsport Dampers with 800+lb/in springs

Just curious...were you and Junior able to install the diffuser that I mentioned long time ago?

Maybe you should just install a racing fuel cell at this point. I am certain that you have already considered this.

travisjb · 03-13-2010, 11:23 PM

Junior, as for the front splitter... it was held up well overall and of course got lots of positive comments from folks at the track... but there are a few issues we need to address

- screw heads stick out on the bottom of the alum plate, and so they are getting shaved off on the asphalt
- as a result, there is a danger the splitter will work loose...
- and it becomes impossible to remove the screws with hand tools because they are half way shaved
- 3 screws completely wasted today... and 1 of the 2 front turnbuckles was disconnected for same reason
- I had to put the car on my lift between sessions and grind off what was left of the screw heads so I could drop the splitter
- It was very easy to remove the splitter once I did that, so props to you for the quick release setup! that part was perfect!

Here's what I would propose:

- the 1/8 alum needs to be an absolutely flat surface with no fasteners sticking out beneath it
- I think we need to mount the alum to the boatboard with bonding material only - no fasteners
- then we cut holes in the alum so we can recess the fasteners that will attach splitter to frame... result = 100% flat surface

I ordered fasteners below that we can try:

#9679 - Machine screws, Phillips pan head, Stainless steel 18-8, 5/16-18 x 3/4
#14350 - Sex bolts - Phillips truss head serrated, Stainless steel 18-8, 3/8 barrel (5/16-18 thread) x 3/4
#14873 - Standard elevator bolts, Stainless steel 18-8, 5/16-18 x 1
#2564 - Hex nuts, Stainless steel 18-8, 5/16-18

damn dude you are intense. This is sweet, We will have to meet and run firebird when I visit my family

ChrisSlicks · 03-14-2010, 08:08 AM

Both the transmission and the gauges use the CAN bus for communication. You might have to go back on a Consult-III to troubleshoot that one.

I haven't had a chance to push my AP brakes to the limit yet, weather still sucks.

The whole system is CAN, thanks for the diag I got it covered.

You need to drill countersunk holes into the splitter, and use tinnerman washers.

I will be out Firebird West this Saturday as well, driving my S2000.

These, huh G-8 TINNERMAN WASHERS from Aircraft Spruce Sounds good. Amazing how many racing parts come from aviation

Look forward to catching up more next week

It's one thing to be on the ground.. it's a whole different animal to be in the air.. LOLOL..

ads370z · 03-15-2010, 11:02 AM

I have worked on many World Challenge GT/Touring, and some ALMS machines. The tinnerman washers were used by most of the top teams, and really are effective and the best solution that I have seen to mount a splitter. This way you keep a flat bottom, no chances of tearing off mounts, and you get the benefit of a washer helping to distribute the load evenly on the mounts.

Let me know if you have any questions. I have worked on a couple splitter designs for GT3 Cup cars, and I have a full solid model of one for my S2000, done in PRO-E. Just dont have the time/money/tools needed to build it

travisjb · 03-16-2010, 11:15 PM

thanks ADS, washers ordered from aircraft spruce!

so... back to a topic that I said was closed... can't help myself... what do you guys think about this one? lol

What's a fair price to offer?
