postive feedback on vw engine blanket

[Eric Madson]

Hey John and gang.

Well the test was performed. I have to say that I was not happy to be the first.

I have had the blanket close to a year now. The fit is still good and that resulted in complete containment.

Snoopy had a oil pump shaft failure at high rpm ( third gear at 34 lbs boost or so ). In turn this caused the center main bearing and associated rod bearings to fail. When it happened, I had little time to get the clutch in and get the chute out. I was worried about oil on the rear of the car and possibily the slicks....not to mention a bit of a fire.

When I got out, the track guys were already at the car as well Kevin Reynolds of the PRA. The first comment that I heard was the track official say "we only have one quarter size drop of oil on the track. Kevin said.."well that proves the blanket works".

When inspected at the trailer, the side of the pauter block was broken at and around the number four cylinder as well the top mess. Plenty of area for oil to cause some real track and car problems.

We will be back some time in the future and be assured the blanket will be on the car!

Thanks John.....nice safe product and I recommend this application to all.

      Sorry to hear of the failure, Eric...

I witnessed the carnage on Thursday evening at the shop,...pretty messy!!

VERY GOOD to hear that that the Blanket did it,s intended job.

I,d have to say that no oil on the track with a catostrophic failure such as that is VERY POSITIVE feedback.

Other than that ,.....I HAVE NO OPINION!!   no need to muddle up this thread!

I have no doubt the blanket works awesome (Looks like the best containment device out there for our VW's), but I haven't seen any temperature figures from anyone.

I run a head temp gauge in my drag car, and just adding a pan under my car that is spaced well away from the engine itself I run almost 100 degrees hotter on head temps going through the traps than I did before I installed the pan. That's pretty signifigant. I can't see how a well fitting diaper like this doesn't create heat issues.

I would be VERY interested to hear what some peoples head temps are going through the traps, etc read under the plug. I know i'm at the limit i'm comfortable at with mine (and i'm burning 'cool' with E85 fuel). I'd love to run one of these diapers, as it's a PITA to fit a pan on my car, but if i'm at the limit right now on my temps with a device that doesn't set against the engine, what am I looking at with one that does?

I'd really like to see some actual figures if anyone has them.

I have ran the blanket the past two races and am very happy with it.  I have seen a slight increase in head temps but not enough be be a concern to me.

we will be out testing Thursday 06.11.09 at Irwindale with the Jagermeister car. I will take my temp gun and get readings from Jons car. I have been very interested in the temps but have not had a chance to log any.

I'd like to see actual temps from under the spark plug.

Run a head temp gauge, and you'll see there's no substitute. An IR gun won't tell you a whole lot.

Not trying to be a prick, but seriously, is nobody running an actual CHT gauge around here so they actually KNOW?

Here's my example guys,

My car (running E85 which burns much cooler than gasoline) would go through the traps at the local track at about 250-275 degrees head temp. As soon as I let off the gas, the temps go down pretty quick. No way I would EVER get a head temp reading by hurrying and jumping out after the pass to see what is going on.

Then I installed my catchpan, definitly not as nice as the diaper, that's for sure. For containment, i'll say it again, the diaper cannot be beat. The thing rocks. But look how much space I still have around the engine for cooling with my pan:



Just installing this pan, my head temps are 350 and a little above going through the traps now. I literally run 100 degrees hotter under the plug with this pan in place.

So, 350 through the traps with a pan that still has airflow around it running alcohol. How hot are heads REALLY getting running the diaper and gasoline? It's got to be huge, right?

It's probably okay if you get towed around the pits, and it's a drag car. But I would really be cautious about telling people things like "It doesn't really raise head temps" and get people to think they can install these things and drive around all day at the track without putting a lot of heat in thier heads. Guys are asking about these diapers to fit with all the stock cooling tin, which to me says these cars will be driving without a tow vehicle. For vehicles like this, I don't think the diaper is a good idea.

Again, covering my ass here, but i'll say it a third time. For the intended purpose, this is the best product on the market. But be careful promoting it to street cars. There isn't any airflow through the diaper, and if you have tins and shroud up top, you basically have just put a winter jacket on your engine, not only is there no cooling air for the motor, but you've also shrouded the entire engine to hold in the head giving it nowhere to shed it.

Just be careful out there guys.

I will say this .. we need test with and without. John was hot lapping the car for his NHRA license and when left idling too long i was not happy with the temp.
I would suggest rmoving the diaper after a run to allow it to cool properly.

I will try to get some more readings this Thursday at Irwindale. John is going for his last two passes.

Unfortunatly, it's just going to be the nature of the beast for us.

Catch pan, diaper, whatever we put under our cars to "do our part" is going to raise temps signifigantly.

I recommend anyone running either contraption to run a head temp gauge so you know what's going on!

The design of your engine oil retention blankets have proven them selves to get the job done with no oil leakage, please put one together for a standard vw engine case running a Berg 4 quart sump and wheelie bar system. I'd also like to purchase one of your balistic flywheel sheild belts for this engine mated to a
Folt's bus trans. Please get back to me with waiting time and combined price?

[Fastback]

IMO, the reason for your heat exchange is because your header is "inside the pan" the blanket acts as a heat barrier between the header and the heads,,,BTW 350 is not "hot" for head temp, What if your race car head temp was 400 degrees with out any device under there .... would you park it or run it ?
