I like how you can hear the throttle shutting (or I guess ignition cutting out) when he is accellerating straight. I heard it a few times.

Seems like a tuning issue.

I just watched 2 more videos. Both cars break up big time in the top end! Awesome... just awesome.

IIRC, they are tuning with a piggyback. Well, they dont call it a piggyback...

MSS54 stays in the car, so its not a standalone.

That would have a been a lot more entertaining if the car was on slicks.

I can recall a few hellrides from back in the day... glovebox flying open dumping contents on unwary passenger, looking out a side window as windshield going 80+ mph down a side street sideways with parked cars lining both sides.

Ahh, the good old days. (I'm glad I survived them).

This is why we are where we are right now with upgrading to a big single on our shop car. Building the kit would take only a couple of weeks. But making sure we can build a fuel system to accompany that and more importantly a computer to control it is the problem. Luckly we are working on all of that right now so there is an end in sight In the meantime hold tight. We will find a way around it and I am sure we will not be the only ones.

Eric-

We're looking into similar prospects in regards to the computer. May have a solution in the near future. Sounds like there are more than a few shops with 335s working on hardware behinds the scenes. I agree the current fuel system seems to be the largest hurdle at this point. Creating a turbo kit / manifolds / standard fuel system seems to be the easiest part, once the electronics and fuel is solved it's just a matter of seeing how much the factory engine likes. I'm willing to bet the initial solution involves piggy backing a standalone over the factory controls with a hybrid fuel system until more development can be done on improving the DI system.

Just for consideration: perhaps run a single natural gas injector in the intake manifold. Don't have to worry about distribution as NG is naturally diffuse. Obvious problem is the big heavy NG tank...

NG would be better before the throttle, so that the gas is 100% evenly spread out throughout the manifold, because the air going into the manifold already has the gas mixed with it.

But if they can make a more powerful DI pump, all the better.

I think that any piggy back with a crank angle sensor can be used to drive regular port injection with gasoline into the intake manifold, be it in 1, 2, 3 or 6 points. Initial tune would be a mess to get through though... You'd have nothing to base it off of, other than winging it and trying to adjust/converge on the right timing.

Thats not the case with DI, which I believe is what he is referring to.

The DI directly injects into the cylinders.

wow is ALL I can say, just wow

[KWY91]

Yay go us N54'ers!! can't wait to see the outcome!

No, he's talking about a hybrid fuel systems. Adding a new injector [for regular port injection], at the intake manifold. (Except injecting natural gas instead of more gasoline).

There were 3 different topics in my response.

AMS posted that CP-E and AMS are working on an improved DI system. My response : YAY!

Comment about how we could time the new injectors, using a piggy.

[roozie2001]

sweet. i talked to chris at HPF about 2 weeks ago. He said once they start lookin into upgrading the turbos theyre gonna look at 2 routes. One being a twin turbo upgrade and the other a Single turbo. see whichever is possible and works best.

damn, hpf piggyback, ic, and exhaust! newb question but what is bpu??

basic power upgrade

i.e. 'typical simple bolt-ons'

*or so I think*

If I recall, didn't Eric@AMS state that there were space constraints with going to a big single?

oh right on, sounds right lol thanks

not at all actually, there are space constraints with going big twins

so, what's the hold-up?

[Eric@AMS]

Fuel no point in building a big turbo kit until we know we have a fuel solution for it. Rest assured if that gets figured out we will be right on this

bigger turbo more lag?

I remember reading that a GT35R (for example) should be able to hit max boost @ 2400 RPM's. I can't speak for anyone else, but if I want to go fast I am not in a gear with my RPM's that low except 1st, which is a traction issue anyway.

N/A as long as turbo isn't too big on this engine/setup.
