LOL not even close. I think we've got the delayed power figured out. Mainly just learning new **** so if I ever get a called for help on a nitrous car, I'll be ready.

I am going to need to adjust the front end, taking 125# out made a pretty big difference in ride height.

I never looked at what effects it has.

How does 30-40% mix help?

Nitro fuel and a turbocharger. That's an interesting concept. Let us know how that works out.....

Make sure to get video of the run, and take lots of pic's of that engine after you get done taking it apart.

So here is the question, I've been working on some calculations to figure it out...

Car went down 300#
Cubic inch went up 20" or so
Motor should make more power than the old one....

How much will I be able to drop the boost and still net the same 60'....
How much will I be able to drop the boost on the top end and still MPH the same...

What size crankshaft?

300lbs is a ton! will make it alot easier to get it to 60' good.

Keep boost same = better 60'
keep boost same = go faster

Does turbo motor work the same way our N20 motor does?
More cubes with same jet = easier on the parts ... thinkin maybe not for boosted motor.

4.000" to 4.250"

Using a rough calculator its telling me I can drop 2-2.4# of boost on the hit and 6# down track and still net the same Hp/LB ratio.

I would love to be able to leave with 4-4.5# of boost. Would eliminate some issues we were having....
