Went to the dyno today.

ive got it set up to see no more then 35psi to keep the drive pressure as close as possible to 1:1

Even at 35psi, over 2800rpms your drive is higher than boost.

I'd love to see your timing table. Just saying.

How clean does it run at your power levels ?

[DODGE74]

It runs fairly clean.

Trust me, your timing is probably way better mine.

Nice numbers

[DODGE74]

Nice numbers

Thank you.

I'll have it back on the dyno here soon and see if I cant hit that magic 600 on stock nozzles.

[DODGE74]

Bringing this one back up.

I never was able to break 600 on stock nozzles because i had an injector go bad on me but, it is what it is.

I have since changed my setup a little, I installed a billet 66/71/14, Exergy 80% over injectors with Bosch motorsport SAC nozzles, Hamilton springs and pushrods.

I went to a dyno event over the weekend and put it on the rollers again and to my suprise it put down 698hp and 1270ft lbs of tq.

I didnt get a chance to look over my logs until last night and come to find out, my pump was struggling to even make 21k of rp.

I didnt put a whole lot of fuel in it because of how small this charger is and it will bury the EGT gauge in a second or two of hammering on it. So it definately needs WAY more air.

Here is a vid a friend took for me. Let me know what you guys think.



Here is the dyno sheet. It dropped some power after the first run and I think its because the operator hot lapped it. He never even stopped the dyno between runs.

Nice numbers!

Older post,

Are you guys finding less drive pressure with a good tune than a stock or Smarty tune?

The only, and I mean only, time my boost was higher than drive was from 1000-1300 rpms. After that drive was always higher than drive. 1.5:1 cruising, 1.8-2.0:! towing, even at 2200. I would get 8 psi of boost at 80 and 13-15 of drive. Pulling hills at 2200 would be 25-30 psi of boost and 40-50 psi of drive. Accelerating above 2700 would go to 55-60 psi of drive by 30 psi. It was one of the main reasons I got rid of the HE351, now I run .7-.8:1 towing. Cruise is about 1:1, hard to tell as cruise boost is 2-5 and the boost/drive gauges are a different scale.

Very nice Gordon! Les just sent me my TEST tune. Wow I am impressed I dont know what took me so long to make the switch.
