on a dyno ??

Todd

haha. yep.. I'm just being a *****. you run in fourth gear because thats normally closest to 1:1 ratio. The dyno regulates the load that is on the engine so it won't bog anymore than they want it too. But from what I see most dynos don't start till 3500rpm..

RETARDED!!! Dude, I wish you were closer down south so I can show you how my 48AR can own whatever AR you have...then you will see how hard it is to play catch up.

I should have my turbo kit finished in about 2 weeks. We can take it to the streets or the track. Either way while you are reving the living ---- out of you engine for power, I will be long gone. THINK ABOUT IT!!!

Todd

Ok calm down and explain to me the difference in first gear.. All other gears don't matter since I am in full boost for all of them.

So how are you gonna get this amazing launch over my turbo setup? What exactly is your car gonna do so I can compare it to what mine DOES do. Bare in mind I'm running on street tires non lsd so I can only launch about 5000rpm and I have to slip the clutch a little to get traction and not to much wheel hop.

Launching like this I have full boost a split second after the clutch is out. I am thru first gear in no time.. Then full boost in each gear after that.

I am willing to listen but I have not heard you say anything that makes sense..

I have not ridden in any car with my setup but as soon as its finished I'll some times and dyno numbers. Everyone around here has Drag Turbo kits which comes with your generic T3/T4E 57 trim stage 3 exhaust wheel with 63AR, restrictive turbo manifold, and small intercooler.

I know what you mean about how a 48AR feels as if you took your foot off the gas in high RPMs but I have a clipped turbine wheel so instead of the Area Ratio being 48, it is probably 50 or 52. I am running a B18B1 LS motor so I will only be reving to 7k.

I am just trying to find the best turbo combination for my LS since I can't rev to 8500. I bought this setup from a guy who had it on his B16 and he said it pulled to redline. There is a fine line between being Quick and being Fast and hopefully I will achieve it.

I am working on a top secret traction setup and if it works I will post it in the FAQ's.

Todd

I think that was the best post I have seen yet..

I have to agree that in your case I would run the stage 3 .48 ar.. it should work very good. Honestly one I get mine tuned well I plan to test a .48 to see what the difference is. I would just like to know for myself.. I am running twin .48 ar t3s on my mustang.. Thats 2.5L per turbo. I only rev to 5500 though.

TWIN TURBO MUSTANG!!! No wonder you don't have any lag. I retract my previous statements,

1. You are rear wheel drive
2. You have twin turbos
3. You have 8 cylinders

What kind of times have you gotten and what kind of numbers on the dyno? We have a guy out here with a procharged Stang with a 150HP shot of NOS running mid 10's street legal. Basically, I stay away from you guys because there is no way we four cylinders can win. If we are beating you, you just spray us with a 500 shot and take the win :P

Dude, your ---- must fly

Todd

haha.. Well I have an sc61 on a 1994 gsr also.

The mustang is not running yet.. its still in the build stage of a very long build. I'm expecting about 450hp to the wheels and mid 11's in the quarter.

You have probably not seen the gsr either.. Here are some pics.. www.overblownmotorsports.com

My manifold is similar; its an OBX SS manifold. What kind of power are you expecting on the GSR? I am only going for 350+ on stock internals. For your car to be serious you'd have to put down 400+ to the wheels.

I say more power for you because you have a much heavier car.

ahahhaha, right good luck on that one.

Are you trying to say that a bigger turbo makes less horsepower in 1st than 4th?? And your smaller one makes more hp in 1st than 4th? No dont think so. Your butt dyno is not acurate man. Maybe the smaller one makes more torque, but not much more.
hp and torque numbers will be nearly identical in all gears.

Also the comment about traction, no way, your more torque will break the tires loose way befor my big ar will. and i can just adjust my clutch cut and driving to not break loose.

Do you see drag racers using tiny ar's?? no. who uses them? oem's and maybe track racers. build what you want but you will not see bigger numbers with your smaller turbo.

A biger turbo will make more power later in the powerband, and when drag racing you will never be below 4500rpm so you only use the high rpm power, ie when your little turbo will reach max eff.


just want to clear this up so no one trades their .6 for a .4 hoping to gain power.
