Disappointing dyno result.
 
Went looking round for someone who can map the mods to the car in hopes of some power and no one could but the last guy said let's see what it can do now so I couldn't refuse lol.

I was so excited to see what the mods could do unmapped and get a baseline before a map is done.
Mods are as follows:
ITG Maxogen (recently serviced)
Piper 270 cams (pulleys not fitted yet they're in the drawer)
Janspeed manifolds
Decat
Piper mid and backbox.

I was expecting a decent result from the mods, the car feels good and seems to give newer stuff a go so I was optimistic.

The result:

What have I been doing the last few years?
All for this?

I'm gutted guys.
I don't know what's going to happen next now where do I start?

So disappointing and disheartening.

At least it sounds alright

Certainly not right. Even the rpm to final figures are different to mine, guess that's the cams doing that? However before mine was mapped it made 191 so quite where yours have gone is something else. You really need to get it mapped, should be seeing close to 210 with those mods.

What are the VIS like? :(

He pulled up a standard one that had been there and it was only 7bhp behind me. A fair bit behind in torque though late in the rev range where the cams kicked in, I was behind in the lower revs in torque and power.

I seem to be able to feel them kicking in fine as I put two new ones not too long ago but I will test them again soon, I'll have to get my name back on the list again

start with the vis, either they're not working or the cam timings way off

Unfortunately these things never go to plan

If you and your mrs fancy a trip to blackpool you are more than welcome to pop round and use my ACR4 which will not only test the VIS motors but virtaully every other actuator and throw up any fault codes.

That aside, are you sure the mechnaic who fitted the cams knew what he was doing as didn't you say he couldn't work out how the verniers fitted hence why they are not on the car.

I will do, didn't think they could cause a big deficit
Didn't think about the timing! That would be easy (for someone else)
If it is that I could get the cams timed in.

I'm wondering if I even have the 270's fitted!

Mark S 30-09-16 05:05 PM

its really below 5k that things look bad, hence looking at vis.

Mark S 30-09-16 05:12 PM
