Default Lsx 261: v1ti convert tt

Hi guys,

Been awhile. We have had the 261 running for a year now, we have the vortech v1ti, it pushes about 18psi, runs around 720hp at 6000.

We are having noises problems with race control, tried all end of mufflers water injection the works.

Converting to twins. Looking at the s200 57-61 the s300 61-68 or precision 58-62.

Anyone with experience shed any light on these options?

Cheers Tom

I had the little s200 51-61 on a 6.0 through a manual

.48 turbine 13psi 650/660
.68 turbine 16psi 740/810

The 57-61 should make at least 25% more and on a 261ci engine even more than that, pretty easily 1000whp capable if the rest of the setup can do it. Get AGP housings instead of the Borg housings, there is a big difference in response.
