Blackwing Intercooler Upgrades Now Shipping!
Last month we announced that Late Model Performance had developed intercooler upgrades for CT4-V and CT5-V Blackwings. Their front heat exchanger is nearly twice the size of OEM and they have an expansion tank that can add another two gallons of fluid to your intercooler system. These kits include all hoses and fittings for complete installation. These have been very popular and as of today all backorders have been filled.

CT4-V Blackwing M6 Brown Belt Hits 800 WHP!
Last March Jay from Louisiana started modding his 2024 CT4-V Blackwing by ordering a carbon fiber intake lid and JB4. Then he upgraded to our Blue Belt Performance Package. Next he moved on to Purple, and now only one year after he started modding he’s running our complete Brown Belt Performance Package.
This week he worked with our partner Recoil Racing for remote dyno tuning. The result is an insane powerband peaking above 800 whp. 60 to 130 mph time is deep into the sixes, even in Louisiana summer air!
We don’t make excuses. We make horsepower.
Now Stocking Mighty Mouse Catch Cans!
Mighty Mouse catch cans are now in stock for immediate shipment. These high quality kits replace the factory PCV valve stopping oil from flowing into the lower intake manifold in turbocharged applications and floor of the supercharger on LT4 engines. Three different part numbers are available for ATS-Vs and CT5-V Blackwings. If you have a CT4-V Blackwing, you can use the ATS-V kit and adapt your own mounting bracket. Or give us a couple months and we’ll have that design figured out for even easier installation.
