71 that was pulled off

RCD 75

Morgans pretty ceramic coated heads :ford:


BP seems be down with some more power on mid and top end. Its hard to tell everything as I changed nozzles too, but I have yet to hit the WG.

Hoping to get on a dyno First of Jun.

I have searched for quite a while and have come up empty. Do you have any data on the 75 (with or without 59) on stock fuel or a thread where someone has the 75 on stock fuel?

Anybody tested the RCD 75mm against the Elite 76mm? Side by side so there is no major conflict.

Just got confirmation my 75/59 will be shipping tomorrow or Thursday (finger crossed for tomorrow) and hopefully I will be able to tell you first part of next week.

I've searched all over trying to find the same thing. Especially with a stock Vgt cause I want to know how it spools having that larger turbine. But I haven't found anything yet either. I may have it within a month or two and I'll definitely post results but hopefully someone has solid info before then.

i have a 73mm and it is hardly any more lag than stock.

I can't hardly tell a difference. Stock fuel, stock Vgt, 3000' roughly.

 

[Morgan@Midwest Diesel & Auto]

The vgt controls the spool up. The vgt is what spools of the line not the atmo. A stock vgt is going to spool like a stock vgt, no matter what atmo you have (within reason). The atmo will come in after you've already made boost off the line with the vgt.

I don't know of any brand or size drop in factory housing compounds that don't spool well enough to drive and tow like a factory truck. Fwiw. May suffer a small amount of low end with a 59mm but it's not very noticeable at all.

Good to know. Other than Riverside with a 59, this is the only other truck on stock fuel I have read about. Are you gated and what kind of EBP do you see at WOT (especially since you are on the stock VGT)?

Good deal. I am sure you will enjoy it.

After I get some electronic misc figured I hope to get some more wheel time. Big drop in egts, doesn't sound different, spools fine, and it'll move.

Edit- I will dyno in the next month like so unless I score a 59mm before hand.

 

[bigaF250]

Jd had the 76mm drop in on stock fuel, no studs and no gate. Also has info with duel fuelers, gate, studs, 60s, and 110s
