project continues

forgetting to connect fan sensor is silly slight coolant everywhere scenario.

do you guys plug the coolant plug, directly under TB? or back to tank?

I also set 43.5PSI fuel pressure, google suggest 58psi, so need to adjust that, ran fine though, but hey, no load..

I think I went a bit silly on exhaust, this thing is soooo quiet, will try to find my db meter, but 80-85 at 3500 or something seems right, the propane heater is way way more noisy than car at idle, with hood open. We do have strict noise track regulations, so I think its all good in that matter, can always just make a 2nd exhaust, that couples on after first damper, or a cutout.

What brand/part number of muffler is it that you used that is so quiet. I want something that sounds good but quiet. I don't want to piss off the neighbors.

Why does the noise matter, your going to piss them off anyway if they drive a rice burner!

Also if they're driving muscle. You'll have something that has the same/more power then they and handles many times better.

the mufflers are custom made ferritas to my spec, I gave them the absolute maximum dimensions I could spec, the mufflers themself are 100% straight through design, meaning its a 3" tube with lots of perforations in it with a 5" aprox outer shell, in between the 2 pipes there is steel packing. I have a pic somewhere, will need to look at my backups. Im amazed at how quiet it is with this kind of design. The mufflers actually ended up not costing much more, than if I were to order something from summit and getting it shipped here.

muffler spec
round center
137mm x 620mm - 3 inch in & out

Oval rear
240x170mm oval with 500mm length, center outlet, offsett inlet

my spec to them was also 90-92db at 4500rpm max under load, which I seem to do easy.

I made a new video with noise when I was behind car, but it has my registration plates etc, so will need to make a new one without, the car makes aprox same noise as my propane heater in low mode. but sounds much better


It will indeed be a sleeper, if we can call it that, as it appears quite stock on outside, if you ignore the obvious things like 1cm bodyroll on track, and 295 tires.. haven't got that many muscle cars here, but sure do got a lot of ricers at the trackdays. when car is working, the 515 trickflow or vengance kit should find its way to my engine bay.

some video of me at track in 2010 with the megabusa, its kinda like sitting in something with fast forward, to bad the laptimes increase 5-10% with passenger, and brake points go from 50 to 100-130 meters.

Thanks, don't think I will be doing custom muffler. That does give me an idea of what I need to look for. A straight through turbo style muffler with packing, as big as possible.

The straight through muffler (like a glass pack) and turbo mufflers (an updated version of what comes stock on most cars) are totally different. The straight through mufflers normally flow better, but are louder. The turbo mufflers are normally more quiet, but don't flow quite as well.

This is a simple explanation of basic muffler types.

E-How Muffler Types

well this f'n sucks, I let my car get fully warm (in our -19 temp) and oil got thin as it heated up, result massive oil spills I located it, its in the AN coupling weld, on the bottom of the tube from sump... of course on the backside, so there is just no chance to tig or mig it... open for ideas here!

Yes by a good quality pan from me!

how much? pic?

well my boss actually came up with a plan (eventhough we are in IT)

put the tower bar on, put jackstraps + chains for safety mounted to headers, drop traverse, drop sump, now to hopefully smart part, drop the sump in acetone bath, then cut out a "window" in the sump from inside, to get access with the tig on rear side, then weld window in again. any thoughts?

plan2, buy new sump.

It's listed on my store site, LS1 modified oil pan

I used sealant last time, do you guys use gaskets or what?

everyone loves videos

That's not leaking, that's pissing!

Is that before or after you "fixed" it?

Admin wrote:Is that before or after you "fixed" it?

this is before... I wont have time to fix it until next weekend, just made a video as "proof" to email supplier. when oil is cold, when it gets hotter, it gets worse and worse and worse...

you can say what you want about RH, but their customer service IS very good, they are taking it back, giving me a new one, eventhough I orderd the kit from them ages ago, even shipping it way out here in norway.

got the rh pan, they shipped it express, and started getting ready to i install it but we had snow so I went skiiing instead I'm now sitting at 3000feet over sea level, we have had 2 feet of snow

the ls1 also just got an old big brother

well I was fedup with everything, including 944 after trouble with my boat, so put it on hold, finally got back to work, swapped out sumps, and fixed all the coolant hoses and pipes, ran it for 90 minutes idle, fans work fine, stage 1, stage 2, then off etc.

0 coolant leaks
0 oil leaks.

wee! more motivation to finish it, not that much left, sent an order for remote clutch bleeder hose I can get things sorted and drive the thing.

edit! my car has a small 4 pin connector, green/black is the tach, I also have nice new cuts from beein up under there.

finished up relays, const power, fuel pump etc

It is alive!

Congrats!!

Its been alive for a while, but holding 6+ wires in the engine room and huge oil/coolant leaks, this is more clean, going to connect oil pressure tomorrow to make sure it works in gauge.. then just need to locate a suitable coolant sensor...

Thanks for replying to my monolog, feels better with more people than me posting :p

After finishing at garage at 22:30 localtime I went straight to a friends party, and showed this on the bigscreen, nobody understood it, and they were not all that impressed... doh.
