I was kind of surprised. Thought I'd get more from a PCM chip than we did. The engine only managed to handle a 4 degree increase on the timing table, and anything leaner than a 12.9 AFR reduced power.
Like I said, I was surprised.
I've done a lot of PCM tuning on my LT1-powered Cadillac and managed better gains using similar tactics. I'm happy with the way she runs and I guess I should be happy with approx. a 30hp gain over stock from only mufflers, CIA and a tune but....

 

30 hp is 30 hp. A gain is a gain.

 

Yeah, you're right. And that's RWHP, not SAE from the crank. Calculate that in and it's more like 40hp gain which puts it at around 300hp, or just about even with a stock Mach 1. Not bad for less than $1000 I guess.
I had just assumed that I'd be able to dial in more advance and pick-up more power than was actually possible. Like I said, it's time to read up on this motor and see why.

 

well it is good power but not close to a mach 1 whose dyno around 280rwhp.

244rwhp is 287bhp with 15% loss.

I wish my car could do 244rwhp.

 

My dyno tuner tells me 17% for a manual trans, 22% for an auto. Taking that into consideration, a Mach 1 w/305hp (manufacturers claim) should dyno around 253rwhp. on a good day. I didn't have a Mach 1 to run a comparative pull that day, I can only go by OEM data and I have to assume that such data is most likely a best case scenario. I guess it would be nice to see some Mach 1 dyno pulls to get a feel for what they actually do in a real-world scenario and if anyone has such data, I'd really like to see it.
The problem with HP numbers and 1/4 mile ET's is they depend heavily on a number of factors, and these factors can heavily influence the outcome. For this reason, I'm fairly happy with my numbers. You're right, I'm probably not exactly there but I think I'm at least in the ballpark.

 

don't get me wrong. You should be happy with the numbers. But it really takes a lot for our 2v engine to make the power those 4v's do.


I know that theoretically a mach should dyno that low but the engine is highly underrated. The Mach engine really puts out 320hp-330hp.

 

You're killing me here.
Just when I thought I had something here....

 

don't sweat it.

The most power you really can get out of a 2v NA is 300rwhp...and that is with pretty much every mod on the market. To make real good power you would want to go with forced induction.

 

Hey, we're in the same neighborhood (sort of)...if you ever want to do a comparison to my Mach 1, let me know, I'll be more than happy to!

 

You might be the guy I need to talk to. I see by your sig. that you have a couple mods that interest me. How do you like the shifter, and how did you do the sequential tail lights?

 

Here is my take on it all.
The shifter rocks!!!
Highly recomend the shifter and wish I had done it sooner.
To wire the sequential tail lights you need to remove the interior carpet and plastic trim off some of the trunk so you can get to the bolts that hold on the taillights. Once you have removed the taillights you remove all the lights from the sockets. With this done you have to turn on the turn signals and move the sockets around. Cant remember the exact order without intructions in front of me. You then splice wires to wires supplied in the kit (AFTER the supplied wiring loom has been threaded through the rubber grommet.).
You have to rewire two of the light fittings but it really is a simple as punching a hole and pushing in a metal fitting. You have to remove the stock flasher unit from under the pedals which is one of the hardest parts of this install. If you are considering the purchase of this kit I suggest you buy the modified flasher unit as well as it looks to be more work than is worth. It really looks more confusing than it is but once you get your head around it and where all the splicing has to take place then it really is a simple install. You can buy the sequential wiring harnesses that simply plug in but you cant get them as 'chase' and for me that effect was certainly worth the 1 1/2 hrs it took to install.

Click on 'see my ride' for an example of the chase signals.

 

Well, I'll let you know once I get them...I just ordered the Tri-ax and sequentials today....once they come in, if you want to meet up, you can check 'em out....heck, you can help me install them, if you want!

 

When I purchased my Mach I made a couple pulls at Modular Depot for baseline purposes and my numbers were 272.3rwhp / 293.8rwtq. MD has a graph, but I don't have a copy anymore.
