Why do my Non-Sequental twins spool like a T-88? :(

I wish I could remember how to convert back to sequential. (And if I wasn't so damn lazy) I'd convert back to sequential. Maybe someday. The lag only really bothers me when I'm tooling around town and I'm in second gear when the rpms are low. I can't shift back into first, so I just have to wait for the rpms and the boost to build, other than that NS is just fine.

Yeah, the first time I rode in a non-sequential car I couldn't believe how laggy it felt. I'm sure my T66 is better.

What gear are you in? In 1st I only make 14lb at 5000 or higher. In 4th I can make 14 by 2500, seq 99' spec. My compression was just check today and is 140ish or 10.0 and 9.7 on reused housing.

I plan to go back to the dyno with the current setup and see if the turbos will put down 450, I am sure that the custom rear turbo inlet pipe I got from you will help

But you have to remember I am a fanatic and since I did the non-seq conversion myself, every mod that would help exhaust and intake flow was done on all the exhaust and intake pieces by me.

That was before I got my air compressor, and had to use a little Dremel. Spent two days grinding away!

Non-seq will not hurt top end, it will only affect low end. At 15psi boost, the low end will still outperform the strock seq low-end.

his motors to anyone at least not for street use! (IMHO)

The same thing happend to a friends new Ito engine last summer, while being broken in, it dropped a side seal.
