RR day results

[karl1989]

spitting flames isnt that carbon build up in the exhaust?. is your throttle arm getting full travel?. mine had a thread behind it stopping it move all the way. heres my graph from the north meet. bosch, gov mod, lda, fmic, poor T2

121.8hp
191 lbs/ft




check for boost leaks and as said get the pump apart and see whats been done

[David]

I dont mean to be on their side...but perhaps the results are not far off...going by some of the other cars...

Just because it has a td04 and pump mods, doesnt always mean it will give the same results as another XUD with those mods.

Did anyone manage to check the belt timing?!

and David...whats your mpgs like??

I get around 600 miles to a tank

[Tallguy_2]

If anyone's interested to do this again there is a dyno that I use just down the road from me,

They run various club days so maybe we could get something organised in the summer if people fancy it?

[David]

I want mine done again!

That was on a Sun dyno wasnt it. Does anyone know what the 'corrected' power actually is, what does it correct for and how?

[the milkman]

ermm david on that video did he bounce it off the limiter at the end i cant work it out on my phone?

---

but as it stands im saying the pumps not been modded right/at all

[MIKE-FORD]

hdi with full system and decat along with remap all by long life = 92bhp email sent kicking off, got number to ring them monday to arrange somethin due to the amount of money spent just to gain 2bhp :/ ROIDS

An that weren't the rev limiter mate that was my car messing up once again. This thing that needs to be done is the pump stripped and looked at

[Anton]

Mike how much did you pay?

[MIKE-FORD]

£250 for map and £250 for xaust feeling mugged and why ive kicked off (am happy with xaust though as sounds like a gti6 from a distance so ive been told)

[the milkman]

yea id start off with pump and make sure timings spot on when putting belt back on. like i said looking at your graph looks to have died at 4k which is either him being a pussy on the rollers or shit/no mod. what does it rev to daily if you went for a hoon?

[Anton]

Jesus!

Seen so many whippy, tb and steve maps pull 120-130 bhp. Id just get a refund for the remap.

fair enough about the exhaust, but you really should have looked for info on here for remaps before you paid that much for a remap from an exhaust specialist

[MIKE-FORD]

i know, learn from your mistakes hay, gonna ring monday the number given by one the main people at one the main branches to see what he has to say

[Dum-Dum]

Theres no point saying the dyno was wrong cos all the cars that were easy to predict we're spot on what you'd expect. Some people cant handle the truth. David you didn't answer the questions in my last post.

[tb205gti]

168bhp was the best of mine with 285 lb/ft

Most powerful pug of the day but my car is f*cked

It actually goes _perfect_ with the amount of diesel set in the file.

The 2.2 makes 2.41bhp per mg diesel. The file is set for 168,07bhp - so it is actually spot on. The 2.2 efficiency is actually a bit lower than the 2.0 - but I hoped that due to the missing DPF the efficiency would climb to 2.0 levels. (2.52BHp/mg diesel). This would result in 175BHp. Torque is also spot on, compared to the theoretical figures.

Do you still have the DPF on it?

Dunno if you have seen it, but I sent you a newer file late Friday - it is set for 184.4BHp and 303lbft. But if the engine is pissing out with oil, then you probably need to sort that leak before giving it more power.

If the engine is healthy, it should be able to make 190BHp without too much smoke.

[Dum-Dum]

Peter if you give me 5 mins I'll send you a pm but the dpf and cat are definitely out.

Im definitely happy with the figure and the curves.

I can take it to 4.5k easy

[the milkman]

just find it strange why your print out is clearly only showing 4k at the bottom then

[David]

David I think your problem is that when they were setting it up on the dyno to start with they have hit the button to set up the revs so maybe they put it as being at 2k when it was actually at 2 and a half and this has compressed your power curve but because bhp is a calculatione of measured torque from the wheels divided by revs if the revs are wrong then the answer is wrong.

What is your torque figure and is that what you expected.
What cars is yours even with in a race and what power do they make.
Where is peak power when your driving on

Torque figure was 210 ftlb I dunno what I wanted for torque but I wild have been happy with 160bhp

Second question I don't understand

Power kicks in at just under 3 and keeps going past 4.5k

[4WayDiablo]

^he means what have you been really close with in a race/traffic light grand prix

[David]

I hant hardly raced anyone tbh. I went up against sams black ph1 dt with t2 and full modded pump and beat him easy and same with just Sean's stage 1 HDI

From what youve described and looking at the graph i really think they set the revs wrong on the machine. From what you can beat id expect 150+bhp and the graph shows your power kicking in at about 2500rpm. Look at the torque curve only as thats whats measured, bhp is calculated from torque.

What ill do later is stretch your torque curve so it reaches 5krpm then from that do the maths to work out what your power would be. That or you can do it yourself. the curve needs to be 40% longer so go into paint and re plot the graph but for every 5 squares it goes across mark the same hight 7 squares across then join the dots and the line should end at 5k then google what the maths is to work out bhp from torque and youll get the right number. For info that would make your peak torque at about 4k which would then make your power 159bhp at 4krpm.

Use this calculator and re plot the rev range. you might find it to be a little over 160bhp just after the peek torque.

I dont think they lifted from the way the power curve appears to hit a wall so unless you have governor issues or some sort of other issue I can only see that a little set up error has given you the issue.

[Arron]

Some surprisingly disappointing results.. but then again some almost spot on/predicted ones, so its hard to confirm if the rollers are knackered or the motors that were down on power have issues.

[David]

If you could do it later for me dude a rep will be coming your way! It just didn't seem right for what iv done to the engine then to show hardly are hp increase. I'm thinking about getting the car rr again next week

[tb205gti]

Peter if you give me 5 mins I'll send you a pm but the dpf and cat are definitely out.

Hmm seems like I cannot see my pm-inbox - I just get an error. :/

[bigcheez2k3]

You have 10 posts now so give it half an hour and the forum permissions should update.

Yeah i realised that as i tried to send it.

you have it in an email now mate.

Did you see what i posted. 159bhp @4000rpm sound about right?

---

My graph. They wouldnt give me the 168bhp one because this one is the better curve.

   

[Just Sean]

David, pm me about rr details if you do go again

[David]

Dum that sounds a lot better and it can rev more still!

Sean I think ill be doing it around the Norwich area
