On stock pulley without E85 it put down 641hp and 652 torque at 5900 rpm, now its max hp is at 5700 rpm with the upgrades. Tuner thinks the blower is maxed out. Just wondering our guys thoughts

Spray that think with a 100 shot under the blower and watch what happens

.. 100 might get u close to 200hp depending on where you spray it. It will also cool the air charge coming out of the super hot blower

BINGO!!! Best way to get you more power with a maxed SC spinning.

Quite simply it takes a lot of air to make 1200hp. The 1.9 without nitrous can't support much more than 800whp ported. Different pistons would certainly help make more power with the 1.9 and 15psi but still would fall way short of the numbers you are talking.

I am not looking for 1200 hp just want to get into the 900 range

Scuzz · 04-30-2017, 10:20 PM

Wrong blower if you want 900 rwhp without spray.

You made 800whp with a heartbeat through a 4l80?

Port it.

15 psi on a B8?? I am having a B8 installed right now, everything I gather is 8psi without upgrading the rotating assembly and rods. Details please and how long ?

For a 1.9liter blower I don't think you should be disapointed with 720rwhp and a MONSTER 772 torque reading. That blower is little on a 6.2 LS. You are asking it feed a bigger engine - It is just maxed out at this point.

Also you shouldn't be afraid to build a higher compression stroker. 8.3:1 is low. When I put a forged rotating assembly in it will 10.3-10.5:1 and will run 13-15lbs out of a YSi.

If you are looking for an additional 180 HP that blower is just not capable of delivering it. Here is the deal my friend. You have an engine that is capable of supporting 1300 rwhp, however your goal is only 900 rwhp. If you lay down a big chunk of money to just meet your 900 hp goal then you will be laying down more money later when you decide to shoot for 1000 and then later even more when going for 1200, etc., you are probably beginning to get my point.

The nitrous guys have chirped in and yes you can go that route I am sure, but then the only time you actually have that HP at your disposal is when the bottle is full, warm, and open.

My advice would be to take a deep breath and enjoy the 720 rwhp while considering air supply options capable of delivering 1200-1300 rwhp whether you use it now or not. Once in place, your air supply will typically not be the weak link due to breakage. Just my opinion.

Yes I did. Very happy with that result. 4L80 likes to rob power.

How much did the 4l80 take your hp down? I'm having mine installed next week.
