I'll take a crack at it.

So I take it this translates to be a 60/70/XX?

Seems a little big on the hot side, but could be usable?

I dunno.

 

[grizzly_man07]

i think it would be good. but it just comes down to price. you could pay 200 for a 60mm upgrade, or buy that turbo

 

[DieselDak]

the 1.00 a/r on the exhaust side roughly translates to a 17cm2/18cm2 housing.

I can get the turbo for $75, maybe less. So it is awful tempting.

It is also wastegated so if I were to pick it up would it be something I would have to use the wastegate with or just weld it shut??

Thanks guys

with enough fuel, you should be able to spool it alright. is it by chance wastegated?

 

[DieselDak]

yup it is wastegated

59/69/17or18??

sounds laggy and top-end-less

haha

 

[drunk on diesel]

you got a compressor map for it? a lot of the smaller garretts have really poor high pressure efficiency

 

[DieselDak]

this is the closest thing I could find to it

not so much to me. the smaller than usual compressor wheel might help spool up a bit and still be large enough to supply plenty of air. and a wastegated 17 or 18 housing could help spool even a little bit more. i know that if my stock h1c had a wastegated 18 rather than a non-wastegated 18, it'd probably spool a little faster than it does now.

 

[Brandonsmokincummins]

i would try it out cause it sound s like it would be ok

 

[grizzly_man07]

for 75 bucks go for it man

ah....shows ya exactly how much i know bout turbos :doh: haha

yeah that's what i say....you could easily sell it for double if ya wanted to....

 

[DieselDak]

Yeah I think im gonna pick it up and see what happens, I got him down to $60, and thats canadian too so its like $5 to you yanks

 

[jimbo486]

we all start somewhere! i was the same way not too long ago as well. just keep reading and talking to people and you'll evenutally pick up on it :thumbsup:

at least i know the numbers and what they mean now :thumbsup:

what's the formula used to convert an a/r ratio to cm2??

 

[DieselDak]

what's the formula used to convert an a/r ratio to cm2??

There is no exact formula to convert the two, just decent estimates because cm2 is an exact measurement and A/R is just a ratio. An A/R can change based on the frame of the turbo(T3,T4,T6.....) as where a cm2 reading is an exact measurement and is what it is regardless of the frame of the turbo.........that being said I found this on the 4bt forums. It makes this turbo more of a 14.5cm2 exhaust side rather than the 17/18 I thought it was. Not sure if it has any credit whatsoever but here it is.



((cm2x8)-7)/100=a/r


6 cm2 = 0.41 A/R
7 cm2 = 0.49 A/R
8 cm2 = 0.57 A/R
9 cm2 = 0.65 A/R
10 cm2 = 0.73 A/R
11 cm2 = 0.81 A/R
12 cm2 = 0.89 A/R
14 cm2 = 0.97 A/R
15 cm2 = 1.05 A/R
16 cm2 = 1.13 A/R
17 cm2 = 1.29 A/R
19 cm2 = 1.37 A/R
20 cm2 = 1.45 A/R
21 cm2 = 1.53 A/R
22 cm2 = 1.61 A/R
23 cm2 = 1.69 A/R
24 cm2 = 1.77 A/R
25 cm2 = 1.85 A/R
