Guys.....the stock oil pressure gauge in the lemons racer does not work.....the replacement sender didn't fix it..... there must be some other problem...ground maybe

I DID buy proper gauges....but for a variety of reasons they didn't get installed....they will be installed after this race...along with a transmission temp gauge

Remember I tested this engine for over 6 hours on track, cut open the oil filter and sent the oil to Blackstone for analysis....everything came back perfect.....our new lower RPM in the corners with the retro oil pan is WORKING..... we even measured the rod bearings to compare wear later...the bearings were nearly perfect...almost 58 thousandths

We ARE NOT going into this race like the last one where we didn't have time to properly test the engine...the high RPM with excessive oil leaks or consumption of the old engine directly contributed to its demise... The old engine was losing 1-1.5 qts of oil per hour on track....the new engine lost 1.5 qts in 6 hours......

My honest opinion of why the last engine died......it was leaking SO much oil that we decided to NOT to use Amsoil (cost reasons...stupid I know) and used walmart special dino oil.....so after about 1/2 the day Saturday that engine was running almost only dino oil.... :>)

Kevin, If you had any clue about racing, you would understand that following a car that has G loading equipment, (S2000 supercharged being followed or following nose to tail) lap times and rpm clearly seen and heard on the video, give all the information you need to know for our discussions. Heck, we are not splitting hairs here. BUT, there is a huge difference of brian running a 2:19 in a 84 automatic and me running 20 seconds faster a lap in a stroker, or 18 seconds a lap faster in a stock'ish S4 5.0L with no oiling mods at all.

Now, you say I dont push the engine as "OTHER" racers? thats funny! who are you referring to? If you kept up with what the holbert car was running at the track, you would see its near WCT times, and has been those times for over 10 years. or you can compare to cup car times today, and take a percentage of those times at a track near you. (less than 8% slower vs the top cup times of today, with DOTs, vs their slicks). Keep in mind, I have run with near 150 less HP vs Anderson and run the same times with the same weight car around the same track. Now, what does that say about his driving if i wasnt even "pushing" the engine. (i.e. WCGT times of 1:40.1 on BFG-R1s vs my '02 times of 1:40.8 on toyos.).

You just misuderstood my analysis of how I drive. driving smart does not equal driving recklessly. (as far as engine abuse) . In otherwords, I always shift at near redline, you can hear me it the rev limiter when I catch it too close. you can also see the WOT light, proving the car is at max power that speed. you can hear the tires, showing the edge of grip. are the tracks that different? well, I have driven at Road America and did the 17second long straights, but the turns and braking points are very close to laguna or Thunderhill as far as duration and speed. We have 100mph kinks, 80mph hairpins, etc. The main difference could be how I drive, gear selection, but generally, its hard for that not to be the same with most any 928 driver. In other words, I would have a hard time believing a driver would carve around turn 2 at laguna at 6000rpm when I can carve around that same turn at 4500rpm and not be at a power disadvantage when it counts.

You watch these videos and tell me where i am not "Pushing" the engine the same as any other racer getting every single ounce out of it.

Sorry Brian,

This is still no excuse.. Ebay can score you a VDO pressure sender for $20, and it can be wired to a gauge for another $20, and wired on a separate circuit by you guys for free on an open slot in the fuse panel, or even to any switched circuit relay to be on when the key is turned...

Just a couple wires, and maybe 30 mins of you guys' time...

Then again, maybe a replacement motor is worth less than 30 mins of you guys' combined time..

Funny.... oil pressure in the motor.... It should also be wired to an alarm buzzer and or warning light like I have on my powerboat...

Anyway, good luck Saturday...

mark kibort

I see where brian is coming from. He feels it is fixed, but it still doesnt change the fact that that early warning system can save the engine if there is some kind of problem, as unlikely as it will be after it has been fairly sorted. Ive monitored oil pressure in my car for over 10 racing seasons, and temps for over 5, and they are just nice to haves, until something goes wrong.

I told brian the same thing, but I think the costs are even lower. put the wires to a meter taped to the dash board and route a wire to a switched hot on the fuse panel. I bet it would take less than 10mins total!

Damm you drive like a sissy...but your foot in that thing!!! Thats the only reason your engines last so long.....its the tenderfoot behind the wheel!! :>)

as for the oiling system in the lemons racer....the pressure gauge doesn't work....the warning light DOES...

mark kibort

Foot is in that thing, but its a tender-one? huh??? See the engine revs? always at or near redline on each shift. (and floored!! )

UncleMaz

I'll send you a 944 VDO OP gauge and sender if you need or want one. Next time I am up at my house I will grab it (week or so).

IcemanG17

UPDATE.....life is an interesting ride.....it turns out the gauges ARE IN and working!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Including the tranny temp gauge...so all three..oil pressure & temp + tranny temp will be functional for Sears Pointless!!!!!!!!!!!

Intial testing (cruising around) shows oil temps of 180F with and idle pressure of just under 40psi.....

WallyP

The Sprint Cup cars are now running 40 psi @ 9000 rpm...

IcemanG17

Ya I'm running 40psi at maybe 900rpm

I haven't seen the gauges yet but the installer said it pegs 100psi instantly!! (cold)

GregBBRD

Much better!

We were about ready to call your wife and have her revoke your racing pass.

IcemanG17

Ha ha....very funny....since she thinks I'm playing golf this weekend

Unfortunately, I do have a clue. For example, how the suspension is set up in two otherwise identical cars running nose to tail with identical lap times will change the apparent lateral acceleration in the engine (tilt and resulting relative angles of oil repose).

So.

If you really are interested in investigating it, install the data logging equipment and share the data.

mark kibort

Kevin, com'mon. you are talking about G loading differnces of two cars runnning the same lap times (and near the same weight)? sure, there could be subtle differences, but not enough to be a major factor. minor factor? possibly.
Now, if YOU are interested, you are free to equip my car with all the gymos you want, so see how a flogged 928 ends up being g loaded around a track at the edge.

Since you say you have a clue, why dont you comment on where Im going easy on my 928 engine . Those videos show not only the new stroker but the 5 liter stock block in '08. I assure you and anyone credible can testify, I was not going easy on it, if hitting redline on most all shifts is going easy.

Thanks, Mark. I really do appreciate that offer (in all honesty). I don't have the money to throw around on things like that. Maybe another Rennlister does.


I cannot spend hours and hours analyzing your driving technique. I did look at your driving versus the Dutch Stallion car at Zandvoort. http://www.youtube.com/watch?v=cIOQA0PtSmQ

Jean-Paul pushes it past the shift light on occasion (~1:39-1:40). At ~1:45-1:48 he is powering out of a LHT and reaches redline and shift much more rapidly than you typically do.


http://www.youtube.com/user/zanick2#p/u/9/ddvWNNBDEp4 For example, here ~1:01 to 1:10 (leaving turn) 1:14 (upshift -- well after turn). Again ~3:09-3:21.

There are other examples of this in the videos. As I said, I do not have the time to point it all out. See SCCA LS ITE Race 2 June 8th: ~2:20. Again ~2:43 to 2:48 (2:52 max rpm).

I cannot imagine how you do not see this. I think you are attuned to the limitations of the engine and drive accordingly. That's obviously not a horrific thing but it is not pushing the engine either.
