Laguna Seca Oct 29th weekend?, Races for 914-4 and 6 Options

[drew365]

Last event at Laguna, I put on new mufflers with the tips pointed toward the drivers side and made an aluminum and 1" sound deadening sandwich board that bolted to the top of my air cleaners and was the size of the hood. I got measured at 97.6db. Lifting is not a lot of fun, you lose probably 2 to 3 seconds going up the hill at t5. I'd rather spend the money on something else, though I really love running that track.

actually, we went through this with scotts tube frame car last time we were there ...

here's what we found:

we were blackflagged with over 105 db during the first practice session.
we didn't have a second muffler, so we tried to cover the engine lid.
but trying to keep the noise inside the engine comp did *NOT* work. it made it worse!
we got black-flagged again (and they don't think that's very funny ...)
we were ready to pack up and go home when we decided to go the opposite route and try one more time ...

we took the engine lid completely off! all the noise went straight *up* into the sky and we passed!
no lifting throttle required, same muffler as before (where we had 105+ db) ...

so apparently, they must measure the sound close to the ground ...

92 db noise limit:
here is what works on a normally loud 914-6.
1) install engine surround metal or fiberglass- if you block off all the top area, ithe noise is just going to escape out the bottom
2) install the stock birdbaths and air cleaner housing
3) install a snorkel to the air cleaner housing with hose coming out to the top of the car. Any deleterious effects of the smaller hose is negated by the ram air when the snorkel is facing forward
4) stock muffler with additional exit tip facing left side of the car.
This is the inexpensive method and will require you to rejet the car - but would you rather race or spectate?

There is a Phase 9 system available with special headers and muffler made especially for laguna, but i hear it costs almost $3500!

Personally, I am going to try my dansk dual outlet muffler with two elbows facing left, and bring a right side cap if its too loud

With regards to licensing; this is a wheel to wheel race and laguna is not the place for the novice to be in his first race in what is usually a very competitive field. I recommend that any entrants have at least one year of wheel to wheel experience racing their cars.

QUOTE (ppickerell @ Jun 2 2005, 08:23 PM) I would love to attend as spectator/914 corral/campground partying person. I have reserved sites for Historics and ALMS (Pcar LMP2 debut!) We stop at Phil's in Moss Landing  on the way down and get a gallon of Cioppino and some Chianti. Let's gang camp! Bring your mountain bikes. Patrick, 914club BBQ! I don't know if I can stay over but I want to attend too... Do you drive down Hwy1 or cut across on 152 to hit Moss Landing?

I usually take 152. I kayak in Elkhorn Slough all the time and Phils is the killer seafood place in Moss Landing.

Thought I'd give this a bump and see if there was any new information.
