So, long tube headers with off road X-pipe, maybe a little blower and throttle body porting and a tiny splash of meth injection, could we see SEVEN HUNDRED REAR WHEEL HORSEPOWER while still retaining bone stock engine internals/reliability?
10rwhp from the pulley? how much more boost did it make if you don't mind me asking. Its surprising how much it made with the CAI since those DI engines have the reputation of being hard gainers when it comes to cold air intakes.
Nice work. Did the car feel much faster after the mods?
Do you think there is more in the CAI with a proper one for the Z06? How modified did you have to make the C7 Stingrays?
Is that the limit on the pulley or will you experiment with a bit smaller while keeping everything else the same?
Did you have to retune the car after pulley swap?
Unfortunately it is raining today so we haven't had a chance to take the car out for a spin with the new power. We hope to do this tomorrow.
The Cold air Box itself fit nicely. With the TB being in a different location we had to fabricate the intake tube from the air box to the throttlebody. We are fortunate to offer in house fabrication so this was an easy task. I do not feel the cold air is being limited by this at all and I would anticipate similar gains with production pieces.
We will be adding a lower damper (over sized) ASAP to see what we can get out of this blower.
Tuning is required.

The upper pulley offerings will be extremely limited due to blower shaft design and the OE pulley already being as small as it is (2.505") We do hope to offer lower pulley configurations for various boost levels depending on what this 1.7L supercharger will allow for.
Right now, we are testing all modifications for performance gains and most importantly reliability. Once we establish both of these criteria we will be selling parts/packages to the public.

We will let you know mid week next week!!!!

The pulley itself did not pick up a tremendous amount of power, but we only went from a 2.505" to a 2.38".. Once we replaced the cold air we saw a significant jump in boost, telling us the intake side of the LT4 is a bit restricted.
As for the DI engine being a "hard gainer" we saw 20+RWHP gains on the LT1/C7 with both Haltech and AFE cold air inductions...

See above. Not difficult at all for us, but not something you can tackle at home. Car sounds amazing and you can hear the additional airflow going into the engine now.
