My Winter Upgrades

Stop by anytime.

I'm thinking about running to MAP tomorrow just to do a comparison pull. It's a week later from when Shane tuned it, so there are going to be some obvious variables like temperature. But just want to run there, and do a comparison pull for fun. Waste of money, maybe, but it's not that much, and it's all in fun :)

Do it! The more comparisons the better for everyone!

OK, got my appointment for just 3 pulls at MAP for tomorrow at 3:30 :)

^ in a way, I think it helps put slightly more perspective on things. Some people never dyno at DB, or LSE back in the day, to know just how different these two dyno's are. So, for those whom are strictly MAP dyno-type, this will show em.

Exactly. It does get a little bit annoying when people tell you that you should have made way more. Then you tell them the dyno reads low, they shrug it off as an excuse. Hopefully this will just be a little more proof. Ideally I should have done both dynos in the same night, but oh well.

I was going to actually, but we ran late last night. So, here's how I came up with stuff..Andrew told me his car make exactly 18% more on both power and torque. I asked Shane what MAra's car made..480..and remember, 563 at map. Hill got just over 500 on db, 589 at map..everything seems to point at 18%..so, I expect 630's from your car tomorrow son!

Car wasn't running too well last night. Today I went and checked the gap on all my plugs. They were all still at .020. I decided to bump them down to .018. I also left my spark plug cover off after I regapped the plugs. Took the car for a spin and it's running beautiful.

I'm not sure yet, but the issues I had last night I'm thinking may be 1 or 2 of these things:

1) Cold weather making me run lean
2) Plugs needed to be gapped smaller
3) Spark Plug cover squishing the wires too close together.

Those were really the only 3 things that changed from last night and this morning, and the car is running good now.

I'm going to leave the spark plug cover off for awhile and see if the issue ever comes back. If it does come back, then I'm thinking it may be the cold weather. If the problem doesn't come back, I think I'll put it back on and see if it comes back as soon as I put it back on.

I'm hopping on MAP's dyno in 2hrs to get a good Dyno Dynamics vs Dyno Jet comparison.

[Halon]

Well did my 3 pulls at MAP today. I saw a 16% difference in the 2 dynos. Also, mine is still miss-firing, but it revved cleanly to the point where it was making max power anyway. So you'll notice the graph only goes to 7k, because that's where I started missfiring.

So the guesstimate of about 15-18% sounds about right on.

Very interesting, I always wondered how the spool would be different on the 2 different types of dyno's on a higher hp car. Looks like the DD spools about 200 rpm sooner because it puts more load on the engine. Nice job brandon!

[MustGoFaster]

Nice! So now do you tell people it makes 628 or 541?

Damn that is a huge difference.. More than I thought!
