GT40-88 dyno charts wanted. :)

[QWIKSTRIKE]

Im at 12psi tuned with perfect a/f ratios on the WB. SARD ecu, SAFC2.

Slips my stock A340e in 2nd and 3rd gear if i let it shift by itself when in boost (have to manual bump it off the throttle and its fine). Full boost in 1st gear at 4k (not bad for the WG slamming open).

Ill have charts soon to support this.

Nice to see this

Nothing is wrong with my 66, I'm just looking for something more efficient. Also I'm just feeling like trying different turbos, and note the dyno differences.

Specs to my knowledge are T66 p-trim, .70 compressor .68 turbine housings.
Non-BB.
For less than $1,000 seems the 4088 will perform where I want it to.
I don't know yet... but if anyone wants my MP T-66, it's always up for grabs.

Make sure you get the Precision 4088. It has the un-devided housing.

For sure, I was going to get it through Dave B.

Just need to get my clutch situation settled... before I go buying better turbos.

I got my precision gt4088 from precision.. lol

 

[MK3Brent]

So is anyone interested in a T66? :rofl:

How much do you want for your T66?What kind of power were you making with it and at what boost? Does it include downpipe or oil lines?

 

[MK3Brent]

I did :

I'll need the exhaust and oil lines for the GT40.

That pull was with 16psi, as you can see it starts breaking up bad up top from the large spark plug gap I was running.

I'll do $550 shipped.



Here's a pull on pump gas:

 

[89turbosupra]

What size injectors were you running? Just want to make sure because Im about to order some new ones.

 

[MK3Brent]

SOLD.

 

[89turbosupra]

Maybe, the hp seems a little low for that size turbo but Im exploring my options right now.

 

[MK3Brent]

Check out the boost pressure

 

[89turbosupra]

What rpm would you see full boost?

 

[MK3Brent]

10.5 psi @ 3500

and most all other pressures at 4-4500

 

[Insidious Surmiser]

nice turbo you got there

 

[MK3Brent]

^BUMP^


SOOOO is anyone else getting 15 psi before 4500?

I remember Howard getting 20+ before 4200!
So I guess I'm trying to find more charts, if anyone has any for a 7M.

 

[annoyingrob]

I hit about 16psi, and do it before 4500, and I'm on a 1JZ.
