LOL I think the back pressure and boost are switched around...LOL

Not gonna lie, I started checking things to make sure an sure enough, they were right! I think if y'all took a ride though, there would be no more second guessing!!:hehe:
 
For a 63 wheel to make 80+ psig by itself, the shaft speed must be measured exponentially. LOL.

I'd love to see some other numbers, such as rpm and possibly hp/tq.
 
Not sure I believe those numbers. No way a 63 is making 80psi as a single and only 50 drive. I gotta throw up the flag no disrespect

Were working on some hp/tq numbers! And as far as rpm, that transducers way to.expensive, the back psi an boost psi ones were bad enough!

Yeah, mother fuk! Thing must be hurtin! What size single? S300 based? I never would have thought that ratio would have not surged like a biotch.

Just saw that it was a 63, got treed bad!

Well it really started coming to life when I got my quadzilla all fine tuned with the 4k tune! I have my rev limiter at 4,100 and when I'm using my lock-up an shifting manually, it never stops pulling through all the gears!

Better check again, throw up a log off boost rolling into it. This isn't Cummins forum.

Boost to drive seems in line and reasonable here for the housing, seems to be every bit laggy however. Looks to me it took 4 full seconds to get into any reasonable boost.

So what have you changed since December 22 logs? OK I will say it, this is bull****. No way a single 63mm Turbo is going to make 86.5 psi of boost with only 52psi of drive

Again here's a piece of Gwoody's log what looks to be a pretty good tip in by the throttle % and the 55% vane position.

Just about 4 full seconds to 10 lbs? Don't seem blistering by any standard.

Have you looked into this charger? Thats the whole ordeal with it is making more boost than back pressure
 
All those were from awhile back. We've both made changes since then. I will do a log from a dead start. It just looks a lot longer time than it really is with measuring every tenth of a second
 
80psi from an s300 and on a cummins motor producing less drive than boost?!?! There be gold in these waters, RRRRRRRR! :p
 
I think you should invest in a set of mechanical gauges before making such outlandish claims.

I can fully believe "oldcarnut" forgot more about turbos than I know, but he will probably tell you the same..... any compressor making 6.5-7.0 PR is a pretty uncommon, much less with a 63mm on 359cid.
 
Yeah the boost to 10 psi on this run took too long. We have seen much better by pulling the fuel back at low boost. The problem that I have at low boost is over fueling. Lack of control due to a boxed tuner. There is a happy medium in the tuning that makes my truck a fantastic towing rig, that was what I was really after. Mr. Blaylock has logged hundreds if not thousands of runs on his truck during the development of the Switchblade. Maybe he can post a couple showing the spool comparison of the stock charger vs the Switchblade. Evidently Lane's truck is fueling harder than any of the other trucks running the Switchblade, hence the 80lbs of boost. :charger:

I too had my doubts regarding that much boost but Lane also has gauges and I asked him to verify that it was matching the gauge, he said the transducer is the same reading as the gauge.
