+18lbs heavier front to rear vs stock ratio

Most of the weights are pretty accurate a few things i didn’t add like perrin cai vs stock and removing manifold just subtracted that from SC added weight.
Rims are about 3lbs lighter but tires are about 3lbs heavier so it’s a wash not worth tracking.

Sweet build! What were your impressions when you first drove with the driveshaft? I've got the Velox cf driveshaft bolted on but haven driven with it yet.

How long have you been using WMI and have you had any issues? We need some photos dude

I didn’t really expect much from driveshaft, i installed it same time as fluidampr pulley, under drive alt/water pulleys and i think the Shorai battery and removing trunk junk. I knew each of those individually would be so minimal I’d never “feel” anything, so wanted to see if a bunch of them combined could make a noticeable difference. I used to thoroughly test everything when i was NA using dragy. If i recall correctly all that combined dropped 0-60 a consistent .2-.3 seconds. My full NA build went from 7.8sec fastest time stock to 6.6sec not bad for an auto. Now it’s a solid 4.8sec.

The 1pc shaft “feels” similar to adding transmission mount inserts in terms of taking out some slop in the drivetrain. It added zero NVH up to 130mph (on closed course :mad0259: ) lol. Never gone faster but doubt it would add NVH even higher.
For most people it’s not worth it. For someone with a serious mod addiction it’s a must have... lol. I think my wife’s going to stage an intervention soon.

I’ll work on some better pics later.

WMI about 1 1/2yrs no issues. Added about 3degrees of timing, lots of cooling, and now combined with E40-45 my timing is the same as it would be with E85, but less stress on fuel system, better MPG, no cold start problems, less 1.5h round trips to the E85 station etc..

Just installed JDM AC delete
Series blue switch panel
Installed 2 intake and 2 exhaust fans on both my custom oil cooler and custom trans cooler and 4 mini fans in my air vents for “AC”
1 switch is for my “new AC” 1 switch for the 4 fans on oil cooler and 1 switch for 4 fans on trans cooler. 1 switch unused atm but my do track box later.

Took a few pics when bumper was off.
Big guy is oil
Little guy ATF

Just went out and hooned around for a while in 82F weather. Oil cooler fans are working almost too well. Had ecutek hooked up so didn’t monitor trans temps yet.
Just for testing while cruising at 25mph with oil at 176f i turned it on and it dropped to 169f in about 15seconds. Turned it off hooned around got it to 210f turned them on and it would take less then 30seconds to drop to 199f while idling at 2 stops / driving 25mph.
Did a 20-90mph pull with oil fans on oil went from 205 to 210 during pull then back to 205 in the time it took me to slow down to 45mph and to 199f shortly after at which point i turned them off.

I’ll have to do some testing later monitoring trans temps.

I was disappointed at the output of the 4 40mm “AC” fans i put 2 each in the two center vents. It puts out air at about fan speed 2. But they are loud, as loud as the oem fans at speed 4.
But i was pleasantly surprised how much air and how cool the air was from the oem fans with the AC condenser/compressor removed. Had windows rolled up oem fans at speed 2 “new ac fans” off. And it really wasn’t hot. OEM fans at 4 and “new ac fans” on puts out a lot of air if i really wanted. really not going to miss the AC i never used. Didn’t like the added load on the engine combined with the supercharger so i just drove with windows down. Now I feel like i can enjoy the ac fans and drive with windows up win win.
