Take the car to the drags again. If your terminal speed is up on last time then no drama.

No harm in having a safe tune, dyno's are only a tuning tool.

Looking at the graph against AFR can help tell you if there is more in it to extract of course, the final number is not important. It is the change in number and it's magnitude across the graph that indicates good things.

Don't get hung up on dyno comparisons, whats the point in having a peice of paper that says 200rwkw if someone can show you one with 170rwkw for the same type of car. A that car is faster and more powerfull where it shows up and where it counts, on the track.I lost count of the number of times I've seen it and the number of people who don't get it years ago.

Just don't sweat it mate.

Well written..i guess it the knowledge of knowing whether your car is running safe and giving you the HP you need. I too don't believe in number...just want my ride to be reliable with many years of joyride left in it. Cheers!

Wot he said above, i agree!! but in saying that every1 would want their car to be making as much pwr at the wheels as possible. I would be disapointed with that personally considering wots been done. Before i put on my pod and was still running standard boost i was making 183rwkws. on my 34 now i got safc2, 3" kakimoto, pod running 0.8 and i made just over 200. Id be getting a 2nd oppinion. Just book it in 4 a pwr run, for like $50 and if ur AFR's are looking crazy on the 2nd dyno get them to do a retune and see wot it gets then. :D

Sounds about right...

Mine's putting out 186 rwkw @ .8 bar on a safe tune with the following mods (also runs 13.9 down the strip @ 100mph on a crap 60ft):

Apexi pod filter

Power FC

Blitz EBC

Front pipe

High flow cat

Cat back zorst

... running standard SMIC and turbo though and wouldn't even contemplate boosting any higher than .8 bar without a turbo that can cope with it.

Cheers.

There seems to be a bit of a pattern here, a lot of the guys that are quoting higher boost levels are actually seeing less power. This seems to indicate that possibly other things need to be changed for it to be worth while running the car at such high boost levels.

I'm not saying this is conclusive, but there is such a thing as too much boost. I'd like to know what would happen with the same car with the boost wound down to more like 10 -12 psi. Perhaps the car is getting excessive knock or something?

Also I'm not sure what pressure the intake valves can take before they start to have trouble shutting, I've heard that this can sometimes be an issue.

Personally just from seeing cars on a dyno day, of the cars that were running high boost levels it was only the ones that were well soughted out that were pulling deacent figures, all others were dissapointed.

      Nah no bearings, just slip fit.  Would be a reasonably challenging but not impossible job to modify it to run bearings but I'm hoping that's not necessary as I may have well built one myself if I end up spending hours modifying it!

      Brumbys with good shells are bloody expensive, I've looked at 2 "cheaper" cars, and walked away from both,  plus after some research spare parts are fairly sparce I'm starting to think that I missed the boat on finding a clean one that is straight (ish) and without alot rust I'm starting to think about a old Hilux as panels and other parts are much more available as they sold tens of thousands of them I use to be indecisive but now I'm not sure

      A Brumby would probably fit a big metal toolbox in the back... this is how it begins

      Picked up a new OEM boot seal for the MX5 today as the old one got ripped a bit by me being a idiot by seeing if I could fit a large metal tool box in it, it didn't fit, and ripped the seal with the corner of the tool box I am still waiting on time to get the cams and new balancer installed, as well as the repairs to the boot Time will not be an issue soon though

      I was more thinking so it doesn't flop around as much rather than for rotating it. Once you have the balance right, it should rotate well enough, depending on how much resistance there is on the pivot. I think you said the pivot point was on a bearing though didn't you?
