Chip......I would likely put bungs on there and use an Annular nozzle.

Outlawd.....you have EFI, why are you not running DRY nitrous

Good question Monte. I have plenty of injector and fuel pump, and I have calibration input for adding/removing fuel when N2O is activated, however, the input is a % shift, not a fixed flow, so I was struggling with how to figure out the best way to equate flow to a %, but I think I have it figured out now.

Should be easy, even if you don't have direct power adder tables.......Lets use some random numbers. Let say your total fuel flow is 400lb/hr and you need an extra 100lb/hr for the nitrous. That's a 25% increase in total fuel flow. Now of course you will likely need to ramp that in based on time, rpm, something........or have a separate fuel table with 25% added starting at any rpm above where nitrous comes on

To recap, what AFR am I looking for on nitrous? My notes say 12.8-13.0 should be really close. I'm questioning this after one of the been there done that types told be target should be high 11's, low 12's and quoted a HotRod magazine article.

Anyone?

I do understand that the engine should run it's best number with the safe AFR with or without the nitrous.

Basically the "been there done that guy" and the Hot Rod article are wrong

To my fellow mopar forced induction enthusiasts....

As I near completion of my procharged small block build, I am having some conflicting thoughts on how to go about getting her ready for tuning. On a brand new build do you guys generally ease into the boost by tuning for lower boost levels first and then moving up to higher, or do you normally just throw all the boost you plan to run at the motor, tune it once and be done with it?

I was thinking of ordering a pulley that will put me somewhere around 7-8psi at first to be a little more on the safe side with the new setup and then swapping to a 15 or so psi pulley once I know that is all working well. I don't know if it's really worth it though, or if I should just save money and time by going straight to the 15psi pulley.



Here is what I'm building up: 69 340 block bored .030 over. Speed Pro pistons (machinist is cutting a small dish into them, he insists there will be more than enough meat to keep it safe from detonation), factory forged crank, main studs, hughes girdle, Eagle H beams, ported w2 econo flowing around 300cfm, head studs and cometic gaskets ported indy 360 intake, solid roller (somewhere in the 250 intake duration range) front mount intercooler, D1SC procharger. Car will run E85 through Fitech 8 fuel injection. A1000 fuel system. I'll be controlling timing through the FItech system using a locked out MSD Billet distributor. FItech has built in wideband for tuning. Hoping we can get the C/R down to 9.5 tops, hopefully a little less.
My goal is to be able to touch 9's in my full interior E body with 4:10 rear once I get the tuning/chassis all worked out. I just don't want to blow it up trying and I know I'll be close.

So my initial statement is loosely correct?

The Hellcat supercharger uses a electric throttle body as a bypass when not building boost. A regular supercharger uses a vacuum bypass I believe. I am looking for ideas on what would be needed to either run the electric bypass or retrofit a vacuum unit.

The pic is showing the bypass itself for reference.

Thanks for any help as this is the last hurdle to make our swap work.

Anybody running a 118 turbo? I just picked one up for my 582 hemi. I know it's not the ideal combo but I want to try it. Any feedback would be much appreciated.

Pretty sure Jason Digby runs a 118 mm turbo on his Predator motor...the black dart that reset the leaf spring world record a few weeks ago in the 4.20s 1/8 mile.

The exhaust wheel and housing needs to be the biggest you can get. I run a 106mm turbo on an Indy -1 motor.


This power adder section should be named after Monte

Let's talk about nitrous progressives...which do yall use and/or like?

I agree this should be named for Monte...wish it had enough traffic for a separate forum.
