Have you considered stepping up to 200% nozzles. The 4294 moves enough air and a number of guys are running them on here with that same setup. It will shorten your pw
which will allow you to actually fuel into a higher RPM which in turn will mean you will be able to make more HP for the same amount of peak TQ and relative CP.
With that change my bet is Beans is gonna want you to use the new stealth and with the 200% its a very good idea. Unless you want to stay with Bob in which case the Pulse is suppose to be a great fit for that. When you finally do that built bottom end and port those heads add a cam etc then those 200% will have room for growth. Or you could send them back in have the nozzles cleaned up a bit by EH'n them. I like the way [email protected]
put it to me when I had asked him. "Striaght 200's can make serious power on a street truck but with them opend up a little and cleaned up like that they can make just stupid amounts of power."
Me likes stupid in this case.
Have you considered wastegating your gt42?
With the money you save from not pulling that engine part or doing the girdle why not take care of controlling that boost and drive pressure. Give you some actual control.
I just had to make that decision. I had at first decided to go with a 1.15 and call it good. After thinking about it, doing some reading and talking to a someone that unlike me know turbos etc I am wastegating it for sure. Other than the, IMO
reasonable, cost added there is zero down side and plenty of positives. You can run the smaller 1.01 housing to give you the best spool up and responsiveness yet still get all the top end the 1.15 would have provided. It will keep your turbo alive.
As has been said about the 910's; use shims. Measure them all and use what is needed accordingly to get them all the same. The extra seat pressure will be a good thing.
