Get the Powell package. Trust me. We basically have the same power/torque and mine holds 2nd the whole way in summer.

 

We have the same power right now 😉 I'm not expecting to hold in 2nd would like to still hold in 3rd but need to fix the weight transfer at WOT

Ryan- have you guys ever brought this stuff to market or are you still testing them?

 

Slackin

 

Was just wondering what happened to these.

 

Good question, along with the higher flowing hpfp upgrade.

 

I'm interested in the HPFP but bought opels and dont think I'll need much more injector

 

I heard that ZZP said that the Nostrum injectors are way out and will probably be too expensive. I'm trying to find the fb post where they were quoted saying this to Princessturbo

 

Ryan (Princessturbo) tells me HPFP should be out for testing in November but the injectors will need some crazy work around to make it work right...

 

Cool I only wanted the HPFP

 

Interesting. All I will say is, unless you hear it from ZZP, I wouldn't trust anything you read online. :-)

 

Well this thread was opened in Feb and we haven't had any updates in months so we just take what we can get I guess

 

FWIW, I know Ryan personally and he got his information straight from Tim at ZZP...

 

Ryan I was just poking for an update it's been longer than I thought updating it.........

 

We have a group of 3-4 people working very closely on that project and things aren't leaked out. Tim's information to Ryan was wrong. He is not one of the people working on that project. :-)

Hey man, its a long process and a lot of R & Ding. I promise, the community will have answers and know what's going on soon enough. its one of the MANY projects we are working on here. :-)

 

I wouldn't say that Tim's information was wrong. It was just misused and taken completely out of context. Stating that some LHU test injectors won't work in an LNF is pointless. They were never intended to. Nostrum is working on completely different injectors for the LNF.

 

It would be nice to have a choice of either 30% bigger and the 50% bigger injectors. The 50s are gonna be too big for most people I believe

 

Ya but if you consider the amount of R&D and investment for just one set of DI injectors, it makes sense to go big. An upgraded set of injectors that will have less flow than the ones currently being developed will likely not be much cheaper if at all I'm thinking.

 

It's not about price it's about having the properly sized injectors to your setup. Id imagine with 50% bigger injectors you'll need all the fuel upgrades when with 30% you may just need a lobe. And also not having crazy low injector pulse widths or going too rich on a low hp engine. The 50% bigger will prob already require way less fuel pressure to idle and drive at slower speeds properly on a low E setup

 

The fact that Nostrum is boasting better fuel atomization, smaller droplets, and lower ipw leads me to believe it will help rail pressure so I guess we will see. Also, what issues do you see happening with crazy low ipw?

 

I know r&d takes time and I'm glad you all are still working on new parts for our dying platform. I'm probably going to need bigger injectors over the winter so please keep us posted as things move along. Don't want to get opels and then you bring the others to market right after.

 

Well yea it'll have a lower IPW cause they are 50% bigger but what is the DDing solution? Have a really low IPW or lower the pressure to keep a closer to stock IPW? I'm guessing lowering the pressure will lose some of the DI's efficiency but a super short IPW will prob require retarding the injector timing so the fuel is still atomized properly. So it'll take a bunch of tuning at first to get setup. If they had 30% bigger injectors running full E would basically be a wash and be quite easy to do. Plus 30% bigger will cover 90% of the guys wanting bigger injectors and the 50s would cover the rest who want really big HP on high E%s
