Man, this escalated quickly... lol. ...
To answer the block guard fitment question. The company making the block gaurd will have block setup fixtures to cut the block, the block will need to be...

Motiv is really doing a great job innovating products, and this is no exception. I agree with sticky that chasing rpm is where power will come from. Adding any kind of appreciable stroke to the...

I guess I view it from the perspective that if I am going to make one and invest the time to design it and source the parts whether they are custom or off the shelf, its just as easy to discuss the...

You make a good point Tony! It certainly wouldn't be the cheapest route, but if we are going to propel the platform forward and break down the 1000whp benchmark, I think systems being designed with...

I agree that line size is critical here.. I've neer used anything smaller than a -10 feedline on a 1000+whp fuel system. That helps alleviate pressure loss due to friction as 3000GT MR...

If the pump feeds were split. You could simply boost reference the PI regulator and no longer need the calc table to adjust for the manifold vs rail delta. From there a simple mechanical pressure...

The way you have the jb4 now adjusting for HPFP pressures, by splitting the pump feeds and treating both as a separate fuel system you will have greater flexibility with the PI to...

It's the dwell period in time to energize the coils. Longer time can help increase spark energy but as 3000gt Mr stated, be careful over charging coils just generates an abundance of heat and will...

Quite possibly cooling, but I think it is likely due to the charge pipe bend directing air that way combined with its exhaust runner being the most direct flowing and cylinder #1 being the previous...

Also fixing the fueling would be simple if you split the pump feeds and made one dedicated for HPFP and one for the PI. Then simply adjusting injector size if you run out. (2) 450lph pumps will...

Wow.. I would have never guessed there isn't an individual cylinder fueling multiplier table. Is it possible it is an undiscovered table still? When you say there is false knock at low boost is...

For those cylinders seeing noise can you adjust their fueling independently from the others? Timing as well? Just curious if perhaps all the additional flow is changing air flow distribution to...

You know I am wondering if it may have anything to do with o2 sensor distance between banks.. If they are sampling with any amount of distance imbalance they could be reading correctly just enough...

Great work! That's some serious modding to the suspension and driveline! Keep pressing, 10's are there with a trimming of that 60'! Congrats on the new record!
11-14-2015, 08:24 PM
Well there ya go..lol Cross that one off the list...
11-14-2015, 07:55 PM
In that case maybe try swapping o2's to see if the banks flip flop..
11-14-2015, 07:38 PM
O2 sensor degradation?
11-14-2015, 07:21 PM
Certainly alot of possible variances.. The notice would appear at first glance to have the most equalized runner lengths, so its certainly possible. Any other motiv kit users out there showing...
11-14-2015, 07:16 PM
It would appear to me that in that instance the car had an underlying issue for so many sets to all be bad? I wonder what the block oil passages look like.. Wonder if some engines may have some...

Is it possible the the new intake manifold is helping the balanced bank to bank trims?
11-14-2015, 06:59 PM
I am curious if anyone has attempted to index the plugs to the injector? My families business growing up was a marine dealership and when the HPDI engines came out they were plagued with ignition...

I think perhaps you are putting more weight then is needed to the importance of deadtime in this situation. Injector deadtime is significantly more important when swapping injector size in an...

Looks like its coming along nicely!

Most of my fundamental turbo knowledge comes from personal experience over the years. I've been building turbo cars since the 90's and have found that if you are around them long enough you...

Excellent work! Can't wait for you to release them! Logs look great, o2's appear to be tracking as expected!
Your making me want to get my single setup going!
