Hi,
As I wrote in my "new members" thread we have strange dyno result of our Typhoon and can't figure out what's wrong.
Just to remind here's car's setup:

-Kenne Bell upgraded oil pump and shaft,
-new piston rings
-new crank
- 160 deg F thermostat,
- Underdriven pulleys,
- roller-tipped rockers 1.6:1 ratio,
- polished inlet manifolds,
- Kenne Bell adjustable fuel pressure regulator,
- Upgraded bigger injectors,
- Kenne Bell air filter kit,
- msd cables
- Kenne Bell throttle body airfoil,
- Bigger 950cfm Richard Chan turbo,
- Performance chip,
- methanol injecion kit,
- Adjustable dump valve,
- Re-cored original chargecooler radiator,
- Samco red silicone hoses,
- ATR battery relocation kit,
- Insulated intercooler & fuel rail,
- Special heat shield on starter motor,
- Stainless braided hoses,
- ATR stainless exhaust,
- corvette c5 z06 GMPP slotted discs,
- Tranny is equipped with transpack, auxiliary radiator and 2800 stall converter.
That's all I remember.
Recenty we had dynoed it and the results are pretty confusing.
With methanol we've got 280HP and 650 Nm (aprox 480 lbft) on the crank.

And here's the dyno which contains two runs 1st is on less aggressive program, and second on more boost with methanol:

I have another chart which compares our truck with another one - more modded:
This more modded configuration is:

- forged Sealed Power pistons,
- Kenne Bell cam,
- Kenne Bell dual timing chain,
- Kenne Bell-Brodix heads,
- upgraded Kenne Bell oil pump,
- Kenne Bell pushrods,
- ARP bolts,
- Crane Cam aluminium roller rocker arms,
- Meziere electric water pum,
- BBK 58 mm throttle body,
- Kenne Bell air-to-air intercoller with samco silicon sylicon,
- Kenne Bell 40 LBS/HR injectors
- Kenne Bell intake with K&N filter,
- PTE 76 turbocharger,
- Kenne Bell headers,
- Borla exhaust,
- hi flow Dynotech cats,
- Kenne Bell heated lambda sond,
- Kenne Bell adjustable wastegate valve,
- Turboxs bloww-off,
- Kenne Bell pulleys,
- 140 Amp alternator,
- Kenne Bell chip
- additional BBK in-line pump,
- NGK sparks,
- MSD 8,5 mm MSD cables,
- Kenne Bell fuel pressure regulator,
- Flex-a-lite double electric fans,
- 160 F Kenne Bel thermostat",
- Crane Cams module + coil,
- Bee Cool wter radiator,
- Derale additional oil radiotor.
- Kenne Bell governer 5000 rpm ,
- Kenne Bell 9" converter ,
- Summit oilpan,
thats's all about its engine ;-),
Here's dyno comparison (run 1 - ourty TY, run2 more modified TY on the same dyno)

Re: Strange dyno chart

wow, peak torque at 1600 rpm, I'm impressed, my shit won't even start to spool then...I will say i am no expert, and I am having a hard time with those charts, but it looks like your spraying meth and your afr's are in the low 13;1's? am I correct?

It's mid 13:1

Re: Strange dyno chart

well, there is alot of different ideas of what your afr's should be with meth. I run mine in the mid 10:1s and have good success with it, but if your running it that lean and not having any knock then I suppose all is well, and might even be better.

on your first run there according to you, your making more power without the meth or the additional boost. Your goofy power curve almost looks like your turbo is way too small and spools instantly and then just can't keep up with the volume. The fact that you can tune and own a dyno makes me think you wouldn't make a mistake like that...

Re: Strange dyno chart

HP and TQ usually cross at 5252 RPM. What's with yours crossing at 3500? Am I not reading the chart correctly??

According to new naming convention this turbocharger name is t63e it's sufficient for mid 10s applications and up to 690 hp.
Just to clarify botch charts.
The first one:
run1: 11psi and no meth makes 236hp,
run2: 15psi and meth makes 262hp,

Please look at the first chart. It's crossing even lower - about 2750 rpm. I know it should be different but for now I have no idea what's wrong.
