Running this TE60 on a stock block with fresh valve springs, supporting bolt on mods. 28psi? 30 or above 30....just making heat at 30psi?
Wanna turn up the wick and wondering if anyone has any real experience cranking this old puppy up.
Precision .63 exhaust housing. Razors kit and possible C12 mix
Max I've had it so far is 27-28psi and it seems to really start building steam after 25
 
You can't get the max flow out of it on a stock engine. With the heads cleaned up I've seen 54lbs/min

I have no idea what the hell that means in regards to my question. Sorry I don't speak Bison, I'm a novice.

If my question was stupid, just say so...........I got a thick hide
 
You can figure horsepower if you use your air fuel ratio and an approximate BSFC based on 54 lb/min air flow. You may be able to google to get some rule of thumb conversion figures. Starts to become difficult with alky to make anything but a guess unless you know your alky to gasoline ratio and can then approximate a BSFC from that. Too many factors though to really know what that turbo is capable of on a stock long block by crunching numbers. Maybe just try a search on the board to see what other have gotten out of that turbo as a baseline.

What he is saying is the turbo will outflow the stock heads.there gets to a point where the motor cannot move anymore air.when you start moving the boost up and the car doesn't use any more fuel you are done that boost range will be higher on your motor say for instance 32psi.now put ported heads on and that same turbo will make only 26psi because with a better motor its harder to make the boost

Your question is not stupid!
Sometimes it's hard to translate Bisonese. Lol
I had in my head by adding a 0 to the end of the 54 lb/min equals approx. 540 hp, but that calculator may be closer.

I get that, and that if the heads are ported they'll move more air and less boost ect....
I was just looking to see if someone in the same predicament as I had found approx where this 60 is no longer efficient. Maybe I'm not asking the right question, but this turbo I'm running seems to go from Dr. Jekyell to Mr. Hyde above 24 psi.
My palms are getting sweaty turning this thing up above 30psi
I guess if I go run it and it's no quicker or no mph gain from say 28 to 30.......I found my answer

Just don't let it knock, and report back what you find. I think Bison was letting you know the mass flow potential, being able to turn that into an ET is something else.
 
ya I know, and I know Bison knows his shit..........problems is I don't. Just the simple basic stuff. I've had good luck keeping the KR away. Motor still has the factory head seal and such.
 
Bison is the man.

Thats a nasty little sub 60mm compressor wheel. It's a torque monster. Good wheel for the turbo buicks that's why they still keep it around.

Even with a pte exhaust housing? Would think you'd need a 3200 stall to spool it which may make it it inefficient w/ stock cam?

I run a Husek 3021 9.5" converter, so getting it to spool with the Precision housing isn't an issue. Car pulls to 53-5400 at 26-27 psi now

Hi, I didn't say anything about a stock cam. Talking about the 60-1 compressor wheel. It makes good power at low boost. The value isn't there against say Bison's MFS 62mm wheel for say $100 more. It's still an exceptional wheel.

Te60 has the stage 3 turbine which is the streetable option imo. Bison has run it with a p-trim .85 and went 10.6x @ 127+mph on a junk engine. P-trim will squeeze more than the 54,55#/min limit ( of a stage 3 turbine)without an issue.
 
my buddy ran a TA60 on a bone stock factory engine including valve springs full weight T-top car went 11 flat at 122 at 30lbs with 100 and alky. 0 pump vigilante. Low 1.5 60ft. I would say if you get 11 flat out of a 60 you are doing good on a stock engine.

With a stock cam and heads it is better to keep the RPMs lower. I run Dave's 3021, and with my setup it is good. I am not setting any records, but overall it is a nice combination. I could probably benefit though from a turbo that can supply more mass flow up to 5300 rpm. With the stock longblock/cam you want to keep the rpms lower if possible (max 4800) and get the most boost you can. Depending on where the converter starts to couple you may want to look at a taller tire if you are not already running a 275/60. I am running a 255/60 and bet a 275/60 would help. The best I ran with the stock converter was a 11.66 @ 113. With Dave's 3021, best is in my sig. Otherwise same setup.
 
Nigel, I'm running a 275 MT Radial Pro...........and yes I used to have a 255 MTDR. So I stepped up to the 275 to try to bring the big end rpm down a tad. I went 11.6 with a 1.80 60' (back peddled coming out of the hole) I forget why, it was last year. Maybe seen some KR I forget

Cool, definitely interested to see your results of tweaking up the boost. I started with a stock setup, and been playing with the car since 2013, so takes time. I stuck with mild parts because it is harder to break stuff. Stick with the parts you have, I bet you can keep whittling away at the ET.
 
Well I hear a lot of folks say that many guys never max out their turbo.........I'm trying to cross myself off that list. I've been fumble fuk'n with this thing since 2008, all I've done so far is Comp 980's and a fresh real main seal motor wise. Built trans myself in the garage with Dave's parts and converter 2 years ago now I guess, and it still shifts like it did the day I installed it. Touch wood :D
