Roxster didn't survive it's first track day - Porsche 986 Boxster track car build 3

It’s going to be so satisfying to see all the previous “mods” stripped off and the car be unpimpified let alone all the actual mods and improvements you make. This is going to be a really interesting build Jeff.

[@mclarenjohnf1]

Jeff the major problem is you were driving with your DRS in Air Brake mode. Considering the fact the car had no real cooling due to the idiot blocking the vents it had possibly overheated in the past and done some damage that just took some fast laps to make it show.

[@ericl452]

Long sweeping right hander with the M96 engine = low oil pressure = rod bearing failure, followed by other bad things over the next couple of seconds. I installed the LN Engineering 2 quart deep sump kit on my 996 to mitigate that problem. Since you had rattling before failure, it probably was the IMS bearing.

Love your channel mate. Don’t want to rain on your Aim Parade but getting a Boxster to GT3 times is nigh on impossible IMO. I guess a GT3 is around 1.04’s?

[@marcmigneault8364]

Oil starvation maybe? Appart from that, going to the track without replacing the brake fluid on that thing was risky. Good thing the pedal never went to the floor. As a rule of thumb, on a road car used on the track, replace the brake fluid once a year. Can’t wait to see the rest of the series!

Suggest you check out the 986 forum Jeff. Much discussion about oil starvation issues when tracking Boxsters. Solutions others have come up with are : X51 oil pan, deeper sump and an "accusump" system. If your engine tear down reveals a no. 6 rod bearing failure, that can be indicative of oil starvation caused by cornering forces.

[@phillipblacklock2615]

I believe Hoovey from Hoovey's Garage ran the bearings in his 996 when he tracked it and from memory he said that the non-dry sump design of the 996/986 led to oil starvation through corners. Perhaps that's the reason Porsche kept the dry sump design for the GT3 and Turbo models and if so maybe a dry sump modification or GT3 motor is the (not cheap) fix ? If that's true, then all non-Metzger (?) engined Porsches should have similar problems if tracked (I don't know whether they do ).

[@svenT16]

Well for what I've heard the problem is in all non Metzger cars... but perhaps someone knows more than me.😀👍

[@guy_autordie]

[@HomeBuiltByJeff]

On street tyres with blown shocks I very much doubt it was oil starvation in this car ;)

[@sportshatch]

Home Built By Jeff an engine will not seize solid without some form of oil starvation . It may not be because of centrifugal forces and may be because of a combination of worn main bearings,and or, worn oil pump. But one thing is for sure it suffered oil starvation .

when do the brakes brakes install a 996 GT3 master cylinder. Its bolt on to a 986 and firms the pedal up a ton.

[@tomkatdj]

Virtually all other engines die of oil starvation in Porsche swaps, the forces in the back are much more severe than in the front. You need a well engineered dry sump to make it work on track, even the standard factory engines don’t last long in track use applications.

[@HomeBuiltByJeff]

Actually that is not true. I have driven and witnessed countless 911's (the ones with the engines in the back) and Boxsters (the ones with the engines in the middle) do endless laps on tracks all over the world completely stock. The very very rare ones to ever have oil starvation issues are usually on super sticky tyres on tracks with extremely long high g corners.

[@tomkatdj]

@@HomeBuiltByJeff nice to have your reply Jeff, but I feel you might be wrong there. So many of the blown engines I’ve seen have suffered starvation, let’s see what yours looks like inside before jumping to conclusions……..my money is on a spun bearing at the far end of the engine, away from the oil pump. Love your work, none of us are perfect, a hint can help avoid a similar issue down the line. I’ve only seen the problem in 911s, but a few times with stock and engine swapped ones……hanging around the track boys in Germany.

Uh-oh, looks like you caught the track day bug. You can tell by the look on your face when talking about the prospect of shaving tenths off your laps. A bit of advice from an experienced track junkie: Dedicated track car. If track days are something you're gonna do, that's what Roxster needs to be. You have the truck and trailer to haul and the reasons for why you shouldn't use your street car as a track car are abundant and obvious. The best part is, Roxster is a perfect candidate for this. It's already been roached-out by its previous owner and it will cost you a lot of money to make it a respectable road car again. Your channel has never built a track car before, so that's something interesting and watchable for Home Built. Pull the trigger. Do it. I'll watch your track day adventures.

[@eddherring4972]

I’m questioning the IMS failure because at least going by the headlights being amber and a 2.5L engine you most likely have a dual race IMS bearing. With the rattling you heard and it getting louder it is most likely a timing chain failure, the results are basically the same but it would be amiss to blame the IMS bearing. The reasons Porsche didn’t revert back to the double race bearing having suffered so spectacularly with the single race bearing were quit clear: 1) The double race bearing placed a lot of torque on the timing chains, leading to stretching and breaking, causing what would later be seen as IMS bearing failure (after all the single race bearing failures came to light) but was in fact timing chain failure, the same result but different failure. 2) The single race bearing reduced torque to the timing chains but increased torque on the bearing, Porsche could swap IMS bearings with a clutch change, just an hour more work but replacing timing chains is a whole lot more labour intensive, slower and inconvenient, involving engine removal and strip down. My conclusion is a timing chain failure due to the symptoms described and the reliability of the 2.5L dual race bearing, given the facts I have stated above I don’t believe you have suffered an IMS bearing failure although if/when you pull everything apart it will look almost identical to an IMS bearing failure.

[@domingos123456789]

Hey mate. That’s unfortunate. I think you should open up the engine to show what broke on this engine

[@Capital993]

FYI your assumption is correct, the brake booster is a common failure on the 986. IIRC there are some updated parts to go along with the new booster as well. Really odd feeling when it sucks the brake pedal down though isn’t it.

Yes it is. Good to hear it is not just this car ;)

[@1one3_Racing]

You're not boiling the fluid. If the fluid boils the the pedal will drop to the floor and you die. It would be the pads cooking if you lose brake force. Regular street DOT4 is fine for most brakes except full race spec. Penrite 600 isn't too expensive. Swap out the fluid, get Ferodo DS2500 pads and remove the booster and ABS. You'll need a manual booster and bias bar to take rear pressure out. That will be plenty.

The best way to make this car as fast as a GT3, is to toss both cars off the same cliff. :P There's no way you're EVER going to get that thing to go like a GT3.
