Latest Dyno runs

[Krambo]

Here is my latest dyno graph. The TQ Converter was NOT LOCKED! 485 peak HP and 533 peak TQ. Its what is under the curve that counts though ;)

 

Things I like:

 

1. Fueling is no issue here. I can hold 11.9 strait through 6500RPMs

2. TQ is where I want it

3. HP didn't fall off in the upper RPMs. It pretty much held till the 6500 mark.

4. This was not an absolute run...i.e. The engine was HOT as one of my FAL fan motors chose to crap out. I expect another 10-15 RWHP on a cool motor. The converter was not locked. I would expect another 20HP to the wheels with it locked. The dyno runs were not for show, just a tool for tuning.

 

Things I didn't like:

 

1. I was only able to dial in a pitiful 3* of overall timeing with the meth and 90 mm TB. I had some KR around 4-5krpms. Hope it is false, but the tune was left conservative on that note. Having 52 RWHP from a 90 TB radix mod is not the case in my application. I would like to see hard data from other's that do the 90 TB as well as I saw NO decrease in IAT's with it and I would say it is worth 10-15HP to the wheels.

2. The dyno had difficulty picking up spark so I would have occasional RPM logs with the dyno curve.

3. I cut my thumb pretty bad removing my front drive shaft and had to get a half dozen stitches

EDIT: The ambient temp was 80* and was in the 50's RH.

Very nice numbers!

[Holty]

Krambo, what are you mods you have done to get those numbers?

[TurbochargedBerserker]

You might try dropping the afr down to 11.5ish for a bit more timing. Might not gain much more however.

[jboyss]

Those are some awesome numbers. What is it with you and cutting your hands?? You guys should have seen his hands after he worked on my radix.

I think im gonna have to send you over a box of these bad boys.

[TBSS]

Great numbers - can't wait to see what more tweaking will yield.

 

On the 90mm TB issue...I'm not a fan of the overly-high numbers that get thrown about with these mods, I don't understand the rationale behind pumping them up beyond what they really are. I routinely see mod increases lumped in with tuning increases and corrections for overly rich or conservative tunes. It's a huge disservice to all of us.

[TBSS]

On another note....where is a complete list of your mods?

I just cut and pasted this list. There are a few minor additions but this is the big stuff. I may try the fuel adjustment with timing Eric. Thanks for the tip.

 

Joe, I have an Elmo band aid right now. My girls love it.

[Holty]

wow, we have basically the same mods, only i have yet to do the cam and 90mm TB. hopefully my numbers will look as good as yours.

[blownchevy]

Nice Numbers! Try a bigger pulley and more timing ;)

<{POST_SNAPBACK}>

 

Funny, of the 10 or so of these I have done the gains have been the same within 2-5 hp each time. 45-50 HP with the TB and the timing that was added. I am able to add about 4-5* on each set up w/o any issues. I am able to run 21-23* on each one of these I do.

 

 

To call it a disservice is kinda harsh......It is what it is, a great mod that nets 45-50 rwhp each time its done.

That's a well thought out set of mods. Must be a monster.

So you're saying that if you take a vehicle that is already custom tuned, that if you add a 90mm TB, you'll be able to get an additional 45-50 HP out of it?

Well, you could consider mine custom tuned....Since John at Magna Charger tuned it.....and yes I gained 48 rwhp from the TB and the tuning. Bolting on the TB will gain you about 20-25 rwhp and the added timing is usually good for the rest.

Tried it. The 2.8 nets the most for me.

 

I can run 18* with no KR.

 

The 90 TB is no way worth 40-50HP on a well tuned application. Gains, yes, the huge gains everyone is talking about,...I do not see it. Like I stated, 15-20RWHP is a fair estimate. I see no decrease in IAT's with the 90 over the 78 hence no gains with timing.

 

I like the mod (I wouldn't have done it if I didn't like it). Just for whoever is thinking they are going to pick up a quick 50HP,...do a before and after dyno run. I would like to see the difference.
