Would like to see real dyno results for a 1200 with header,muffler mod,ecu Programed. I can’t find one. Everybody says that u should run at 8800. Would like to see hp gains above 8500 without changing cams.

On the dootalk thread look at post #27.

Hope you got what you are looking for. JC

Lots of stuff but no test where rev limiter is raised. Thanks for that info!

[CanGadeX]

No. The Dynojet system from what I have read does not increase rev limiter. This info at least shows you actual numbers which are impressive. I like that they started with the base point non mod sled then added programmer to it. That alone shown and increase. From what I gather studying this along with other dyno and testing info, a fuel tuner is a must for max gains.

I agree looks like 147 is all you are going to get

[CanGadeX]

Nope had another dyno sheet and its over 150hp.

Good results hopefully will get someone with test that has ecu programmed with higher rev limiter

That is a good point.  According to my butt dyno 8800 definitely makes more power than 84-8500.  I always say my 1200 is 150-155 ish.

So as it sits most u get is 152hp. Guys run at 8800 for more top end not because of more hp.

Some guys used to run modded 1200's up to 9100 rpms no problem

Imo from reading about these for 10 years and owning 2, there's no extra hp up above about 8300 but it doesn't drop off, so you spin it higher and use gearing advantage to make mph. This is for the average bolt on (header, ecu, muff mod) 1200 anyway.

My 09 was a beast compared to stock. It was header, mod'd muffler, Cudney clutching and ECU flashed running at 8900 rpm. It consistently beat my cousins 800 etec pretty easy and hit 117 on the speedo. For a renegade with 16" wide track, no wind protection and my 230lb butt on there I thought that was pretty good. Stock I don't think I ever say more than 105.

 

You need all the mods to be fast, not just some. I first installed the clutching and header and found almost no improvement in power and speed. The ECU flash and rpm made it a whole new sled.

That makes sense.  8800 for me is definitely the sweet spot, lower is okay, anything higher and it seems to fall on its face.  I changed out a primary spring last year from the 1131 to the 1133 and as much as it states only the start force is different, the 1133 with same weight in the pb80 and the sled was much slower.  I was disappointed but then I added about a 1/2 a gram and the sled felt much much better hanging at 86-8800 instead of the 88-8900 it previous was at before the added weight.

I am slowly getting parts to get me the same results. Any advice on which or who to reprogram the stock brain? I see different companies out there that offer this e.g. Cudney, Bondi, Boost etc...

[BCX]

My order for programming would be boost, bondi, Cudney. Boost engineering seems to be the most popular
