awesome engine.. The fabrication is really nice.. Good job on it.

Thats how i've done it before, but what i meant was the wastegate is not "spliced" off the 90, its the other way around, so the turbo would get a more turbulant airflow. Depending on how good the inside is.

Know what your saying on the customers always right.

Sure it works great either way

Engine bay nicely filled.


...don't mind the gatorade bottle catch can. Just temporary until we get the right fittings!

Installed a new 68mm TB from our sponsors at Skunk2!




Love the aesthetics and function of the Synapse BOV. Also use a Synapse FPR controlling pressure of 750cc RC injectors.






A little jury rigged but we're using an Innovate LC-1 wideband hooked up to both our S300 ECU and AIM data logger.






Ovalized down pipe and flex/cat tucked up high for ground clearance.

Will,

Did you lay up your own CF sheet for the splitter, or buy it that way? If you bought it, where and how much?

Why are you keeping the cruise control? Is there a lot of highway driving for the One Lap? Surely you could maintain a steady speed without it. I guess it could be more relaxing though, and save your energy for the more important stuff.

Oh, and if you know someone looking for the dual master setup, I couldn't make it fit my setup at all, so I'm letting it go.

bsclywilly

I laid that up on an aluminum sheet and vacuum bagged on the underside.

Yeah, One Lap covers 3500miles between all the track sessions so for sure cruise control is a must!

Sorry to hear about the dual MC setup not fitting your SC setup.

Off to the dyno in 1 hour!

Makes me proud to be Canadian when I see such masterful and well thought out planning going into a car from fellow Canucks... Everything looks incredible. Post back quickly with numbers.

results????

Pull from 2800 to 7800rpm.

I'm so scared for that turbo. The angle really makes me think it will live a short life.

Beckerton

That exhaust lit up like you flicked a light switch...numbers?

bsclywilly

No numbers yet. We got fuel tuned up to 19psi and just started to touch timing but was too late in the day and had to pack up. We were seeing 20hp gains though with just a few degrees a the point that we had to stop. Will be back on the dyno again later this week.

I love this. I just learned about twin charging in the Lancia Delta S4 and now I wanna do it. Either that or all motor. Is there a way to buy this for the public? and is this a Y7?

namewasdallas

Now that you said something about the angle it made me think that that turbo may starve of oil or the turbine wheel maybe shouldnt be sitting at weird angles like that, but maybe im wrong.

Also I'd heat wrap that exhuast manifold

96EJ6LX

What mounts you got? That motor didn't move an inch when you let off!

weiRtech

wrapping the exhaust will cause it to crack. if temperature is an issue i'd rather see it ceramic coated inside and out.

bsclywilly

Poured two part polyurethane in the stock mounts to make them solid. A good thing because the turbo sits about a pinky width off the frame rail.

Shouldn't need to wrap the exhaust. I've got heat shields for electronics, and heat wrapped or fire sleeves on coolant, oil drain and clutch lines. That's always the preferred method rather than insulating the exhaust.

96EJ6LX

All these parts your making... you should "sell" (give) all of them to me. Lol

HamiltonRex

Cool stuff man! Was that dyno pull made before you started to work with the timing?

bsclywilly

Hey Eric, yeah that was just after we finished with fueling and hadn't touched timing yet.

Returned from the dyno last night with a modest tune. 300whp@7350 and 248lbft@4650. Will be plenty for One Lap since reliabililty is paramount over performance. We were just starting to see the turbo come into it's own so when we get back, sleeved block goes in and race fuel to see if we can hit 400.

The twincharge setup didn't offer much top end gains but made for an ideal power band for road race. For the tracks we race we typically see minimum rpms of around 4k and minimum WOT rpms around 4.5k so this should be just perfect for laying down the power.

Current tune:




We also tried bypassing the SC to see what effect it has. Here is a turbo only curve at 16psi. Looks like typical shape for a turbo plot. Drivability would suffer at the lower rpms on the track.




And at the same boost level a comparison with twincharge. Torque curve is flattened out and wider by about 1000rpms.

96EJ6LX

Nice dynos man. Keep it up. 400hp outta a single cam

Jaker

What boost was the 300/248 achieved on? That's the kind of numbers I'm hoping for from my M62 Endyn setup. Looks like the blower added 90 ft/lbs at 4,000. Any way to get the blower spinning a bit faster sooner? What size pulleys are you running? You have a 60ft/lb jump from 3,500 to 4,000.

Also, is the splitter pure carbon or is it sandwiched with anything (foam core, balsa, plywood, etc...)? Polyester or epoxy resin? What does it weigh? How stiff is it? How thick was the aluminum plate you laid it up on? I know you're probably busy as snot getting ready for One Lap, so I appreciate any information you have time for.

bsclywilly

Hey Jacques, no problem, there's alot on the to do list but atleast the car is up and running now.

A very thin aluminum sheet will do, just need it for a nice smooth surface that could be released. I think I used an .035 sheet. I replaced a kitchen window in the house recently so now I have a 4x6' glass panel to do layups on The core is 5/16" plywood for durability and with four attachment points, it's stiff enough for me to stand on the lip which is about 8" from the front attachment points using the tow hook bolts. 2 plies carbon on either side, epoxy resin. About 1:1 resin/fiber ratio by weight. 16 lbs or so, I think.

Bottom end is quite beefy for track. What we'd want to do is spin the blower slower so we have more top end. The blower takes about 15hp from the crank at max speed to turn. Plus another 10C (-2% fuel) it ads up to about 20hp loss at the top with the twincharge. That is why some people insist on a bypass. I prefer drivability and simplicity. 1.52 SC pulley ratio.

wow i just noticed this is a single cam.


i like it even more. haha :D

Justin Jones

wow, beautiful build, really impressive. my mind is blown.
