Re: Single turbo 352 iroc 1000hp or bust the grand finale
You would have had it done months ago had you still lived here, its a shame you're on your own over there. I'm waiting on you brother, mine is done and ready to go. Exhaust is a wrap, re-tuning is complete, but won't post anything until I find time for the track, or until yours is at least moving under its own power. You running 12-psi with a solid sixty foot, and holding the throttle down without lifting should net you sub 11.50 times very easily, in fact I would be shocked if you run any slower than that...

Re: Single turbo 352 iroc 1000hp or bust the grand finale
Depends on what HP the stall was rated at. It's not an electronic device that releases a clutch at a specific RPM. It's a guess based on fin size and angle.
My converter stalls around 2800 on my 412. On a smaller engine it would stall closer to 2400 rpm.
I agree with shooting for top MPH. I don't know about you guys, but I can't go faster than 11.49 without spending another 7k in safety bs. I can run up to 139mph though. Light the tires on fire at the three and drive it like you stole it.

Re: Single turbo 352 iroc 1000hp or bust the grand finale
... what I meant was it is a lot like cam manufacturers. Most companies immediately assume that the buyer will ask for too much, so getting what it was advertised for is not really always the case. Final say is when he throws up videos to confirm stall speed if people really are curious though, and if that is what he ordered then hopefully that is what he got. I don't think it will stall that high though, even with more horsepower, but that's just my opinion.
I think sizing a converter on a turbo car is tough anyway. It's not like a n/a car where you have a flat power curve.

Stall is gonna change with boost. So it may get to 4500.
Mine was suppose to be 4500-4800 ish as it seems to flash in there on hit off boost but if boost is high and it comes in fast, it opens up more like 5500-5800. I once forgot to take brake off the dyno and tried a pull it stayed at 5500 on just 15 psi boost

Re: Single turbo 352 iroc 1000hp or bust the grand finale
before i go im going to put it on the transbrake and see were it goes, im sure it will go 4,500 on the brake , footbraking it will prolly only goto around 3k before the brakes cant hold it
must resist using brake at track for giant smoke show though that poor 10 bolt will become a grenade im sure even on street tires

Re: Single turbo 352 iroc 1000hp or bust the grand finale
Let me just clarify. The transbrake will hold well beyond your stall point, as this is why some racers will leave the line already in boost. Your stall is determined by hooking up a boost/vacuum gauge, torquing the engine up while holding the brake, and once you see 0 on the gauge, that is your stall point. The converter will still "flash" way after that because flashing is sudden, but that is not your stall point, that's your flash point. The transbrake will hold well beyond your stall point, but that doesn't make it your true coupling point. This is why I said I doubt you will see 4500-RPM as your stall point, but should in fact see 4500-RPM as your flash point...
#312
Re: Single turbo 352 iroc 1000hp or bust the grand finale
What don't you understand? A converter's true stall speed is when you apply the brake, torque up the engine normally, and when the vacuum/boost gauge hits 0, look at your RPM, and there is your stall speed. Flashing the converter is not done that way, flashing the converter is simply mashing the gas suddenly and flashing it higher than its rated stall speed. Example; D6 converters stall at 1600-RPM, but flash in the low 2000's. D5 converters stall at 2400-RPM, but flash at high 2000's. What is so hard to understand?
#313
Re: Single turbo 352 iroc 1000hp or bust the grand finale
Flash stall is as you say. You mash gas launch vehicle and observe rpm at which vehicle starts to move
But where do you get this idea that true stall has anything to do with vacuum??
True stall can only be tested by transbrake where drivetrain is locked and you bring rpm up until converter stalls and no longer rises any higher. That is true stall. Engine will not keep reving on transbrake.
Flash speed is always gonna be lower than true stall because forces in the converter will start moving vehicle well before rated true stall. Thats why a car will move forward in gear at idle with 4500 rated stall. Its still capable of transfering torque just not alot but sometimes enough to move the car

Re: Single turbo 352 iroc 1000hp or bust the grand finale
Stalling the converter and flashing the converter are two entirely different things, thus the reasoning behind the two terms. Flashing the converter will always yield a slightly higher RPM point depending on an engine's horsepower, but this does not make it the "true" stall speed. True stall speed is exactly that, when an engine couples with the transmission normally, and this is easily determined via watching the boost/vacuum gauge, or datalogging. I can control when the converter couples with the transmission by doing a neutral drop, but this does not mean that is the stall speed of the converter. Incidently, nobody said a transbrake will not help find a coupling and/or stall point, what was said was a transbrake will hold past that point, that is the purpose of a transbrake, to build boost while holding the engine back from moving, but that does not make it higher than what it really is. If that is the case, I will go out and rev my engine to 6000-RPM in neutral, slam it into gear, and now I suddenly have a 6000 stall speed converter...
#315
Re: Single turbo 352 iroc 1000hp or bust the grand finale
I will trust major converter manufacturers definitions of true stall. Go try it. Get a converter and a brake. Push and hold brake button and see how many rpm the engine can achieve before it gets "stalled" lol key word there stall. Thats stall speed.
Finding 0 boost on a gauge is irrelevant.
Carry on

Re: Single turbo 352 iroc 1000hp or bust the grand finale
Look, everyone has their own opinion when it comes to converters and how to calculate true stall speed. Foot braking is the most common method if the brakes hold, flash stalling is the next of course but not very accurate in my opinion, and of course there is now transmission braking. A simple datalog used in conjunction with all three will tell everyone what they need to know and narrow it down in the end. Getting back to what I originally said before it was misconstrued, I don't think he will be able to stall at 4500-RPM. Why? Because we are talking about an engine, that in the very page before this one, is hoping to run an 11.50 pass. I just don't see the engine making enough power to bring the converter that high. But as I already said, test it and we shall see...

Re: Single turbo 352 iroc 1000hp or bust the grand finale
That car with cleaned up heads and half decent sized cam should have no problem getting 11.5 power on mild boost.
Totally depends what the converter was made for. Its quite possible it will get to 4500. If its a nitrous converter from a 9-10 sec car then no it may not get to 4500.

car really needs a solid roller cam to make the best power just wasnt in the budget right now , but i expect the xe274 to do fairly well

Re: Single turbo 352 iroc 1000hp or bust the grand finale
It is my understanding that converter stall(for boosted apps) happens at 0-1 psi, and flash is when the converter couples at max power.
Also, I didn't see anyone mention anything about the stator when configuring the converter for a certain stall rpm, as it also plays a role.

Re: Single turbo 352 iroc 1000hp or bust the grand finale
You will never get flash to couple at max rpm rating because there is not enough load on the converter. Do a launch in 1st gear and see one flash point. Do a launch in 3rd and see another flashpoint. But car will move at some point near 100% couple but never at that value. Only way to see where it "couples" is when drivetrain is locked so only the hydraulic part is spinning and seeing engine torque load.
Can you share links discussing stall as it relates to engine vacuum or 0-1 psi as you mention? I have never heard this and dont see how thats relevant at all. Its a hydraulic device. application of trq input to the fluid trying to hold it back from slipping is the only thing that matters
If it was designed around torque at 20 psi which would be upwards of 700-800 wtq then at lower loads its likely gonna be a few hundred less rpm

Re: Single turbo 352 iroc 1000hp or bust the grand finale
if they got the converter right i should be able to build close to max boost ont he brake , the trick will then be getting the car to hookup leaving with that much power
#323
Re: Single turbo 352 iroc 1000hp or bust the grand finale
You wont hook most likely on max. Nobody ever leaves on max. You will have to find that limit to what it can take, and then work on ramp rate on how the power comes in. Boost control and timing are your friends there
Only thing that matters with converter stall on boosted car is that you can get some boost at the line somewhat quickly on the brake before overheating the fluid, and that it doesnt blow thru slipping past your peak hp rpm. If it stalls anywhere inbetween peak trq and peak hp, its gonna work fairly well lol
For me in the 1000 whp range, i try to leave on 5-7 psi and if track holds i let it come in as fast as turbos can produce it. Got me 1.31 60 in this 3800 lb rig. If track doesnt hold well i gotta ramp, leave 4-5 psi and do something like a 6-9 psi per sec ramp. That will get mid high 1.3's sometimes low 1.40

Wow, that is some interesting opinions of true definitions in regards to stall speed.
Can someone answer this? I have a manufacturer rated stall of 1800-2000 rpm. The vehicle will foot brake to 2600rpm making 2 PSI at 30% throttle. At 0 PSI, it is around 2300 RPM. What is the stall speed?

Thats why buying a shelf rated converter really can vary. Gm replacement for a stock 305 lets say its stall rated 1600. Slightly build motor and more torque it footbrake stall goes to 2000 with good brakes, then the true stall on that particular converter is gonna be somewhere around 2000-2500.
True stall shall vary on power. Thats what i see in my logs when i go from 700 whp levels to 1100 whp levels. Its a good 500-600 rpm difference

Re: Single turbo 352 iroc 1000hp or bust the grand finale
Since stall speed is dependent on input tq/power, and as boost builds so does tq/power, picking an arbitrary boost pressure to determine "stall speed" is just that, arbitrary. What is relevant is that the RPM the converter stalls at, while the engine is making the desired launch power (or launch boost if you prefer that metric), is an RPM that is desirable based on the engine's power band. You want to leave with 850hp and 4800 RPM - you need a converter that stalls at 4800rpm with 850hp @4800RPM input from the engine, any engine.
Boost is just a different metric - you have a hydraulic coupling with an input and output, locking the output (transbrake) and applying a certain input power (whatever your want it to be) determines the "true" stall speed of the converter @ that input power level.
Flash stall deals with dynamic/momentary loads on the converter, and is a very complicated load case and can show a variety of "stall speeds". I'm not going to go into it LOL, unless everyone has a solid grip on FBDs, dynamics, fluids, and some general impeller design knowledge

project has 350 cubes, if he can tune it to 1hp/cube before boost (easy enough) and throws 10psi at it should be in the neighborhood of 550 crank HP, I would think he can get into the low to mid 120MPH range

Put down 424/536 at 24-psi with very conservative timing controlled by the EBL, horsepower peaked at 5000-RPM, pull was as high as 5500-RPM; 11.68 @ 116 in the 1/4 and getting faster

If a v6 goes 120 on 14 psi that v6 must be modded and car is lightweight
I honestly expect 115 on 14 psi with my stock 305 lb9. Math points to 450 hp max at 14-15 psi and 36 lb injectors
My mild first gen 401 build went 135 on 10 psi. 3700 lbs. i'd expect your 350 to go mid higher 120's in 10 psi

The Gen 3 60v6 heads flow very well compared to the irons of the Gen 1, and 8445 heads. Bob's Buick has champion irons and the champion Hot-air intake. Full weight too. Used to live down the street from him and have seen it, driven in it, watched it roll down the track. That thing was impressive even when it had the TA33. I love that car since its an underdog and most people look at a HA car as a slowpoke.

Lol i will go 11's on this car and i am in about 1600-1700 bucks haha
Other idea was to freshen up the 401 and drop in a stock rebuild 305 to my black car already setup for drag. Really find out what a sbe 305 can do. But i dont think it needs redone for atleast another season

Re: Single turbo 352 iroc 1000hp or bust the grand finale
heres that upper hose rob
cars prolly not going to start tonight i forgot my money when i went back so i couldnt pick up the stuff i needed to hook up the fuel system , just ran home now so i could grab my money and stop by at napa
im going to use the rest of the night to dbl check all the wiring and other stuff and then fire the car tommorow
now that the car is just about ready to fire up i can slow down and take my time and make sure everything is good

Re: Single turbo 352 iroc 1000hp or bust the grand finale
Are you running the stock ignition coil without an MSD? And how are you supporting the turbo weight?
Get it done - watching anxiously - best of luck.

Re: Single turbo 352 iroc 1000hp or bust the grand finale
stock coil no msd box yet , i may go coil on plug this winter so i didnt want to spend the money on the msd stuff just yet , that being said the stock coil + the megasquirt doing direct coil control will fire pretty dang reliably under a good amount of boost with the plugs at .025-.030
i havent made the suppotrt brackets yet but there will be a bracket bolted to the waterpump to support the wieght of the turbo
hoping to have some videos up tonight of it running without the turbo
