I searched for awhile and couldn't find a thread like this, which suprises me..




When you are cruising and make a pull:

When do you start making boost?

When do you make full boost?


I know there are a ton of variables...

CID:
Turbo:
Boost:
Crossover size:
Intercooler:
Charge piping size:
Fuel:
Trans:
Weight:
Tire size:
Gear:
Stall Speed:

Full boost by:


So, lets hear it guys..

You should add tire size and gear to the list ...

and add converter stall speed

but to answer your question
CID: 325, stock 5.3
Turbo: on3 76mm 1.0 ar divided
Boost: daily driven 10-12 psi
Crossover size: 2.5"
Intercooler: 4" core 31x13 3" in/out
Charge piping size: 3"
Fuel: 93 octane
Trans: TH400
Weight: 4300
Tire size: 28''
Gear: 3.42
Stall speed: ~3200

Its kind of hard to tell full boost with the converter but its very fast. Below 3500 for sure

For this to be useful it would be better to see screen shots of data logs.

Full boost by:3400

Tough to figure out with the stall, I might be off a couple hundred RPM...give or take.

The camshaft used, the dynamic compression that camshaft gives you, your static compression, cylinder head and port design, timing, afr and a lot of other things will also determine when and where full boost or any boost is reached.

My 346, 241 headed, 227/224 114+2(I didn't choose this cam), 3800(more like 3600) FTI stall, 3.55 rear gears, 10.33:1 compression, 93 octane with 100% methanol used for secondary injection, 3900lb. race weight, 4" charge piping, 2 1/2" crossover equipped car made full boost(15psi) by 4000rpm with a PT76 turbo.

When do you start making boost? 1700 rpm

When do you make full boost? 2500 at 75F or cooler


I know there are a ton of variables...

CID:6.0
TurboTE 72mm, Garrett based
Boost: 9-12 most common
Crossover size: 2.5
Intercooler: PTE 1000hp air-water
Charge piping size: 3 inch
Fuel: Pump premium
Trans: 80E
Weight: 5500
Tire size: 275 55 20
Gear: 3.73
Stall Speed: 3200

Full boost by: 2500 at normal temps, will go up to 28-2900 at 100f.

I think total amount of boost should also be given as that will change the rpms that full boost is seen.

You should add tire size and gear to the list.

427, what size ar on turbine housing are you running? sounds like what im lookin to build for dd. also whats the max rpm u spin to? and is the turbine housing single or divided?

427

iTrader: (3)

I don't remember the AR. The trans shifts at 5500rpm. The housing is open.

Anyone else have a turbo?

I see full boost at about 6000 rpm 3rd gear at end of quarter, with a D1, 3.4 pully 7.65 crank.

With my f-1c i saw 24psi at 6700rpm now with my f-2 i set my rev limiter to 5700rpm and i'm around 26-27ish peeing water from heads, but before i set rev limiter the first time i stomped on it; it caught me off guard and i happen to be looking at boost gauge and it flew by 30psi+ by 6200rpm. The only reason i know rpm is i was logging data. My Kpa was maxed , only had 2bar os in the process going to 3bar os. Head pulley 4.5 crank 8". Pre pro charger the F-2 would max boost with my pulley combo at 6600rpm. I'm already toasting my 345's tires so for now 5700rpm is all i need.

ok guys, op is asking about turbo setups. Almost everyone on here knows that a centrifugal blower (procharger) makes boost with with rpm.
