Exhaust bits coming in. Hooker header, Magnaflow 5571437 CARB resonated midpipe, GWR street single muffler.
Header looks well made. Hope the whole setup isn't too loud. Plan to do some A/B dyno pulls to see what the header makes on a bone stock NC2. I'll be happy if we hit 175whp after E85, reflash and intake. I'd rather not open it up for cams and valve springs. https://cimg7.ibsrv.net/gimg/www.mia...50fbdacd0c.jpg https://cimg2.ibsrv.net/gimg/www.mia...b90c52e1fb.jpg https://cimg4.ibsrv.net/gimg/www.mia...5f80021c27.jpg |
Progress on drivetrain. New driveshaft, prototype Supermiata Sport clutch. Production Supermiata light aluminum flywheel (in stock). Trans is a blueprinted NC1 6spd from Walter Motorsports in GA. We have been using WM for our built transmissions for a while now. Highly recommended if you're going to be beating on it.
5spd 78.5 lbs 6spd 95 lbs OEM flywheel 16.1 SPM flywheel 8.3 Clutches should start shipping around May of this year. 5 and 6spd variants. Puck or hybrid (Kevlar/organic) disc. https://cimg6.ibsrv.net/gimg/www.mia...3b94a4a087.jpg https://cimg7.ibsrv.net/gimg/www.mia...0dc6cda919.jpg |
That's some great news on the clutch, if that would be at the same price point as the exedy it can be the new industry standard.

Wow, I didn't realize the 5 speed was so much lighter than the 6 speed. Are you using the 6 speed because it should be stronger?

Sneak peak of our new wheels. Still many months away. The final wheel will have further machining detail on the spokes and be tilt cast + flow form. The VIA test wheel is actually forged.
Standard load is 690kg and 100k cycles for forged, 125k cycles for cast. Normal cornering fatigue test just goes to 125k cycles and stops. We're going to test two identical wheels until failure to better correlate to our in house FEA fatigue sims. We'll test at 830kg. We hope to be able to more accurately correlate our FEA data to real world. Anyway, the clear coated and otherwise rough test wheel is still damn pretty. Facebook Post |
Looks cool. What sizes and applications will be first?

Brake things.
12.88x1.1 Superlite 7420 pad Many bump travel https://cimg4.ibsrv.net/gimg/www.mia...9f96cff5bb.jpg https://cimg8.ibsrv.net/gimg/www.mia...f8914981a5.jpg |
What, those pads don't come in orange? I am disappoint.
|
They do in some compounds :)

I hope those brakes will fit my 17x8's for when I drive on the street. They look massive, so probably not...

These are a pair of Coto test wheels. We're using these to run a VIA test protocol here in the US. We'll use the resultant data to refine our in house FEA results.
These are 18x10 +40. Rear has a 12mm spacer. They were too pretty to not mount up and take some pics. These test samples are a bit different than production wheels will be. No 3D ball mill in the "U", thicker outer flange and few other small changes. We'll also paint the production wheels. No plans for the bare CNC & clearcoat finish of the test wheels. Meanwhile, Kaiko's header is getting ceramic coated. Once it's back, we're on the road. Planning the first track day in a few weeks at Buttonwillow. https://cimg3.ibsrv.net/gimg/www.mia...8ddf31a8cd.jpg https://cimg6.ibsrv.net/gimg/www.mia...a143d13cad.jpg https://cimg0.ibsrv.net/gimg/www.mia...68a3575f11.jpg https://cimg1.ibsrv.net/gimg/www.mia...803188e0b5.jpg |
First track day with engine mods
First track day with the engine mods last weekend at Buttonwillow. Weather conditions weren't ideal for fast laps but we had fun. Very windy. Base set up was really close right off the trailer. Only change we made was bumping front RB sway bar from middle to stiff setting and playing damping settings with pressures. Ended up 6 clicks front, 5 rear. 600/400 springs. I want to try 700/450 next. Also swapping to the larger Progress sways for next event. RB is 25.4mm and we had a 16mm Whiteline rear. Progress are 28.6mm and 17mm. Needs more front bias sway bar rates than what we had.
Still rubbing rear tires on inside pretty heavily despite 15mm spacers. That's with 18x10 +45 and 265/35 RT660's. Bumping to a 20mm spacer to see if that cures the rubbing. Less rubbing in front (no spacer) but I think we'll need to add a 5mm there too. Gearing way too tall with the 6spd x 4.1. Barely got halfway through 4th. Needs like 4.77 diff with the power we have. Nothing OTS so we'll have to get an RX7 R&P adapted or something custom made I think. Also needs more power. Too much tire for the 155whp I'm guessing we have now. Would have been faster with 245/40 on 17x9's I think. Ran out of time to get the big G Stream wing on but glad now. It would have just slowed it down. Really don't want to pour a bunch of money into this build as it's just an occasional toy for us. Definitely no turbo, Not a fan of 2.5 swaps because I like revs and don't necessarily want to build a full forged 2.5 longblock. ITB's, maybe, but they're not cheap and I don't look forward top getting it tuned. Cams actually make sense along with the flexfuel kit we ordered. Maybe 165-170whp with cams, dunno. Haven't had it on the dyno since we put the exhaust and intake on. Currently Hooker header Magnaflow catted high flow midpipe with resonator GWR street single muffler CPT (ebay) CAI with AEM dry filter Ecutek race rom with my tune. Got a little coaching from Matt at Orange Virus. Was struggling with MAF calibration, crazy lean no matter what I did. Gave up and called him. After a few tries he gave up on MAF and switched to SD too. I finished up safe base tune for this weekend. Need to get on dyno and start proper tuning. Doesn't feel much faster than stock now, maybe 5-10whp bump from stock. We'll see once we get it on the rollers. Big Superlite 12.88x1.1 prototype brakes were bitchin. No ducts or anything so we plan to fab some defectors. Balance/bias with R12 front and R10 Gloc pads was perfect. Castrol SRF. Kaiko is pretty porky. 2440 lbs w/ fuel, no driver. https://cimg7.ibsrv.net/gimg/www.mia...409e78d186.jpg |
Nice to see it finally on track. When it comes to the ITB's, the complaints I see are just for street drivability, but fine on track. For the 4.77 rear, how about just doing the RX8 rear diff swap? The S2 RX8's had a 4.7 stock and the rear hubs are stronger on the RX8 or something like that.

Ben Herne (Puddymod) just responded to an earlier msg and he can do a 4.77 swap in our NC diff so we'll go that route. |

stupid question maybe (& I've probably missed the info if posted:bang:) but, whats the origin of the NC diff? is there parts interchangability with NA/NB 7" or larger like the Bongo / Ranger diff?

Your MAF issues are likely a dirty MAF sensor. I usually can get the MAF dead on within 2-3 flashes unless the sensor is nasty. Building a SD tune for a header and intake pipe engine is lulzy, but I am glad you have gotten it on track :)
The correct scaling for the CPT intake is stock*1.1873 FYI. |
