Perfect for motorway driving.

How about this one for a REVO Stage1 car.

Just one or 2 additional mods.

I was there on Saturday when you ran.

Small, unassuming chap that commented he used to have one of these.

Yeah, I remember! I wish I had known at the time as it would have been good to chat a bit more. The ex dumped the kids on me that weekend so I couldn't hang about.

Another 300+ lb/ft on a Stage I :eek: ! Are you guys serious - what am I missing here?

And 266 bhp? C'mon, the p*ss usually gets taken out of anyone who falls for any remap company's propoganda of getting 250 even with mods. Got aviation fuel or nitrous oxide going on there?

That's much more like it! What are the mods, do you know?

Yes. :P

There are loads of examples. Some different mappers and all sorts in here. JKM Rolling Road day Gallery

I hear what you are saying. I have been all through the JKM pics, performance graphs and descriptions. I see the torque differences but not 250+ bhp on only a Stage I

Ben, any reason why your curve has been measured using a 6 cylinder turbo scale ie. SHOOT_6F? Think you might want to have a word with the dyno operator imo

Figures/curves showing 250+ bhp on Stage I have generally included the fuel pump mod and an induction kit as a bare minimum.

.............. and a final comment regarding this curve, this was the result of several additions to the car (the main one being the fuel pump mod and Stage II+ from REVO) but you should note that the fuelling was found to be way out and in certain areas fluctuating to extreme levels.

The car was then subsequently extensively tested and retuned by REVO themselves until a satisfactory medium was met meaning final figures of 280bhp and 325lbs/ft.

HTH

:rotz: Then I guess that makes the graph completely useless!! What effect may that have on the figures?

I have no idea what the implications are to the overall curve but I would certainly be questioning why this basic calibration was not set correctly in the first place!

I can only expect that it's because every other car there apart from two were 5 cylinder turbos, and I suspect it doesn't have a 5 cylinder mode.

Sounds like I need to go back for another (free) run and see what happens. And I must get to JKM at some point as it would be nice to get some continuity.

Ah Mr Fish I was wondering when you would see this.

I also don't know the implications regarding the correction factor but that would also mean its wrong for the 5 cylinder cars as well.

There could be an answer here but we can't download them.

Ahhh! I am glad you chipped in here (no pun intended) Mr Fish as I have been meaning to ask you about the fuel pump mod as I think you could give a 'grounded' opinion on this. The whole issue is somewhat confusing to a newbie when searching the threads on this. There are threads rating the HPFP mod as the best performance mod after a remap itself whereas others talk of it only being useful for those actually experiencing fuel cuts or thinking of going Stage 2+. I couldn't identify RR graphs of Stage I only vs. Stage I and HPFP mod but it sounds like they are there.

Wanted to get this right as the APR pump seems to be the way to go these days and at £700ish it's a lot of dosh!

@ muckipup. With what your current map is asking I would save your pennies. Some maps have seen gains from the pump + other mods however these tend to be the more aggressive ones. e.g. REVO

All the pump does is force more fuel into the standard fuel rail, the by product to more liquid in the same volume gives the greater pressure.

So instead of running the rail at 110 or 115 bar they run it at 130 bar all the time and let it sort itself out.

To get the most out of it you really need to be stuffing enough air in there as well.

Given that Makefish has pointed out that my graph was done in the wrong mode and therefore the figures are of no use for reference it's difficult to say.

However I know my car is running well and is pretty quick, quicker than it was before with another vendor's stage 2 map on.

At the moment the jury's out on the fuel pump for me and the point of going on the rollers on Saturday was to see what was possible without changing the pump. Unfortunately it looks like I'm no closer to that given that the run was measured incorrectly.

I think you should speak to the company that did the run and ask them what the implications are.

It may be possible for the to just change the correction factor and recalculate.

I am currently waiting for a call back from them

Cheers. I take your point. The reason that I am asking was because I was a bit dissapointed with my Stage I map. 231 bhp was nice with the Pendle map and the torque curve was very smooth but it fell short of 240 lb/ft. My idea of solving this was to ditch the current map in favour of a Revo - seeing (if I am seeing it right) a Revo map producing 220-something bhp but much higher torque compounded this even if it meant shelling out for a HPFP and a CAI if that was the secret.

Can you post a graph of yours muckipup?

Torque is all well and good and everyone loves headline figures to tell their mates in the pub but the delivery is what matters. A big spike at the beginning that tails off quickly might feel fast but in the real world it isn't necessarily.. and high torque means high boost.

On another note I just spoke to someone else with a set of DD rollers, the shootout mode doesn't matter unless they were measuring the rpm using an inductive clamp which they weren't.

Can you post a graph of yours muckipup?

Sure, it's this one on JKM's website:

http://www.jkm.org.uk/performance/Misc/Gallery/rollingroaddays/SCN%2019%2009%2009/Dyno%20Graphs/VST.gif

The graph looks pretty smooth to me, do you have any other mods? If you asked Pendle there may be a little more in there for you who knows?

I wouldn't take that stage 1 as gospel. It was my old Octy and didn't always play ball.

My best figures were 300lbft and 232hp on the same dyno and I would expect to see a good 230+ bhp and at least 270lbft.
