it's the T-60

 

Wow, that is great for a T-60...nice numbers. I am now confident I will make some decent numbers using my T-63...of course I could always put on my big daddy T-72.

 

Jerry,

At what rpm does the turbo start to spool up, and at what rpm is it at full boost? Also, at what rpm does the turbo cut -off at?

Are there options for different turbo rpm ranges?

Thanks in advance,
Dave

 

Never paid attention to what the rpms were, but the boost come on rather quick. No noticable turbo lag.

 

Judging from his turbo size and his dyno sheet I'd say full boost on that dyno run was at 3100rpm or so. On the street this can vary though. My dyno sheet looked like it took till 4300rpm to hit full boost but that is only because we didnt floor it till 4000rpm or so.

On my GT35 the turbo never "cut off". Now I did stop making additional power above 6000rpm but I didn't lose power either. Just stayed flat till 6700rpm.

By playing with the turbo size, A/R and ehxuast housing size you can custom tailor your turbo kit to work exactly the way you want it to. If you want it to come on hard and strong way down low you can do so but you may sacrifice top end power or total HP capability. For towing purposes that would be fine. If you wanna race it then you'd go bigger turbo for max power but you will end up with at least a lil more lag than the aforementioned setup.

Turbo's are sweet in that you can run a fairly large exhaust housing for max HP when racing and for $150-200 you can buy a smaller exhaust housing for daily driving and swap em out pretty easy on these rear mount kits.

 

Full boost at 3100 is nice. So where would it start spooling up? Around 1800-2000rpm? And full boost would run up to 5600rpm, right?

I'm not sure where exactly it would start spooling on a normal truck. Mine has a 3000 stall so it basically hits full boost before I have time to look at the guage. I'll mess with it tonight and try to get some accurate #s as far as spool time etc.

And yes, you should see full boost till you hit the rev limiter.

 

thats about it dave, i't work great for towing and a little drag racing.

 

Now all i have to do is get to the track and see how far up the fastest truck list i can get.

 

Great idea Erik, I'll have to get to work on that. If I could just get to work on that really big box in my dining room (guarded by many cats - BigTex), I'd almost be there.
