i saw a similar happen thing to an sc300 at a dyno day once. just kept on chucking silicone connectors. only it was at the throttle body.

i am sure you will find a permanent fix.

good luck.

Update

Ok so during the week we fitted a dual stage boost controller, new hks bov, fixed cooler piping all in preparation for the dyno today to get the tune sorted.

Swapped out the plugs for some colder plugs to start it off. Then started the tune. New manifold makes boost come on around about 600rpm earlier which im stoked about. Started to set things up for the power runs. On 20psi it made 220rwkw but fuel pressure was dropping at this point.. So we put boost back down to 16 psi and it made 200rwkw. Did a few more pulls and fuel pressure kept dropping. Something was wrong.

Luckily we had a spare deatschwerks 300lph fuel pump on standby. Swapped that in and luckily that solved the problem. Did a few more runs on 20psi and everything was all good. Made 250ish rwkw on 20psi and 185rwkw on 15psi. For the yanks out there.. thats around 335rwhp and 250rwhp ish..

Safe to say im stoked. Cooler piping issue is sorted. Everything is looking really good. Cannot wait for sunday now haha

Dude that is mind meltingly cool!!

I can not imagine what 330Hp in a mx5 feels like.

so I was contemplating on selling my NB for an S15, but after seeing your youtube vids I kinda wanna turn my NB into a money pit

[Magpie]

Congrats Charlie.

nice work mate.

on 20 psi that is about the same power to weight ratio of a 997 Turbo S.

Awesome Charlie

when's the next outing in it?

Oh - was this done at gt auto's new place?

[charlie_91]

[Crooz]

Just keeps getting better and better.
Are you coming out to the Downshift meet today?

[charlie_91]

So did something ive been wanting to do for ages. And that is make it so i can put stuff in the boot with the wing on.

So this morning i took the boot off and cut some slots in the side to make it work. Bit of touch up paint and put it back on. Works perfect. Very happy to be able to put all my track sh*t in the boot instead of the passenger seat.

Here are a couple of pics of how its mounted for those that want to know.

update:

So another trackday came and went on sunday. This was a different track with a different setup during the day. They had sprint sessions, cruise session where you could race people on the straight and a skid pan. Was setup to be an awesome day.

Started bright and early that morning. Met up with some mates at the servo local to the track for some breaky before we headed out to get setup.



Got setup, did driver briefing and went out for the first sprint session.


What a technical track, a lot difficult to master then the previous one.. Little to no front end grip coming into the hair pins and along the high speed sweepers it was an arse clenching experience being top of 5th with not much track to work with.

Screen shot from harry's lap timer gives u an idea of the layout.

Next up was the cruise session. This was so much fun.. having re reign of the track and racing whoever we please. Was good to test out the new power to
So much fuel


heres a quick race again an s15 with an 3076r.. Making a fair bit of power i cant remember how much. Would have been good if we took off the same

Lining up ready to go out for another sprint session. Started to find my grove here and was really enjoying it



Next up i decided to try out the skid pan haha.. So much fun but difficult at the same time.



This is where it gets pear shaped. After the skid pan session i went out for another cruise session and then the car started playing up. I went back to the pits and flocked around with it for a while till i concluded that it was running on 3 cylinders.. Somewhere in the wiring harness there was an error and it wasnt sending a signal to No. 1 Injector. As i wiggled it around it seem to fix it just breifly but then went back to 3 cyinders.. Thats where my day ended.

For the rest of the day i was passenger in a couple of mates cars which was just as fun. Came time to go home and i got it running back on all 4 so quickly made my way out the gates and on the way home. About 1 km into the drive car started struggling a lot and air fuels were going crazy so i pulled over.. Was barely running by this point. So i decided to just call a tow truck before i do any more damage.

Took the bumper off while i waited for the tow truck.


admired the crazy as skies going on behind us




two hours after calling the tow company the truck arrived and picked me up and took me home.


And thats where i left it... Time to take out the harness and start trouble shooting the cause. I really enjoyed the skid pan so i wanna start learning how to get sideways and hold it properly

Update:

So since sunday we took the wiring out and started stripping it back to see what we could find... It was pretty dodge to say the least. So much for a mate helping me out by making this. I wont go into what actually caused the problem as there could be a few reasons. So we are building a new harness from scratch

This will solve all my issues and its something i can have piece of mind with Thats underway now but i wont be seeing my car till after World Time Attack in sydney next weekend

I also found that im hitting my cooler piping under brakes and compression so as ive never been to happy with how this actually fitted i decided to re route it back inside the engine bay.. This will make it much easier to access and should solve my problems. Plus i can re use that pipe just by cutting and re welding bits and pieces win win.

Went down to the hardware store and picked up some flexible pipe used in bathrooms Good thing about this is you can actually set a shape or route without loosing it so it worked perfect to find the right path.



Also have this coming in the mail this week


Very keen to say the least. Ill be using this when the big wing isnt on.

Updates next week

[Lokiel]

I'd be wary of using your flexible bathroom hose in an engine bay - sounds like a recipe for a meltdown.

You need something more like this: http://www.flyinmiata.com/index.php?deptid=4536&parentid=0&stocknumber=22-10050

i think it just there to mock up the path?
