The Dyno graph Thread - Post yours up!!
 

going on from the other week, here is the dyno thread :) post up your graphs and specs, doesnt have to be a saxo, just nice to see what ppl are getting with what mods, and good info for ppl looking at where to spend their money :y:

ill start with mine, brief spec being 90bhp vtr engine, low compression on decomp plate, standard internals, turbo converted with t25 currently, running predator management, pretty tame ignition, if anyone's interested in a more detailed spec it's in my thread- link in sig :y:

got 2 sets of graphs, first one was on 10 psi just after mapping, had issues with exhaust, injectors and fuel,

made 134 ATW, 165Lbft and 163bhp fly, think its around 15-20% transmission loss on this dyno,





next set was about 6 weeks later?, same dyno, same guy,

id put a new exhaust on, new injectors and got a remap @ around 15psi boost, had only just sorted an issue with induction/feed on the morning of the dyno :n:

graph highlighted as i was suspecting, im still having fueling issues, pretty sure now is down to a combination of fuel pump and FPR becuase of other issues i sometimes get, but the car made :

218bhp fly and around 230lbft torque, cant find the wheel graph for this one, but was about 185ATW iirc?





NOW POST YOURS :bump:

AX VTS 16v, Ph3 cams, 3.5 bar FPR, standard injectors, raceland mani, hydra nemesis ecu, straight through exhaust.

was that an actual hub dyno as it sais? or was it measured at wheels?

Piper 270 cams
No remap
Raceland manifold
Some sort of gigantic cone filter
Decat
Piper exhaust

8v, Green cotton filter, 3" Pugsport, Raceland mani.

103.2bhp @ 5350RPM/~104ft/lb @ ~3300rpm



And here's why I always say a rolling road figure means nothing.


16v, 3" Pugsport, Raceland induction kit.
119.6bhp @ ~6300rpm/113ft/lb @ ~5100rpm


Then on another RR, exactly the same spec as above...

142.8bhp (that's all the info I can gather from the pic).

Clio 182 standard on dastek rollers


After exhaust and remap

My old legacy B4
Hayward and Scott exhaust
Decat onnthe 2nd turbo

Spot the gap between the turbos!

Saxo Vts
Catcam 743's (evo1 on rs graph)
Raceland 4-2-1
Straight through 2 1/2" centre pipe
Magnex rear box
Port & polished throttle body
Remapped

Rs tuning - Leeds - Dyno Dynamics - (Without P&P TB)
144.1 bhp
117.9 whp
18.39% T/loss


Northampton Motorsport - Northampton - Superflow (before & after P&P TB)
151 bhp
126.9 whp
15.961% T/loss


Revlimit is 7750 the last run on the NMS graph revved over for some reason but it didnt effect the power, if anyone can explain that id love to know!

Surrey Rolling Road - Surrey - Dyno Dynamics
141.3 bhp
115.6 whp
18.19% T/Loss

106 turbo

Td05 big 16g with 8cm2 exh housing
C2 inlet
At power throttle body
680cc injectors
Omex 600 etc etc

249@wheels and 210lb ft torque@wheels at 13psi





Seat leon cupra R

Scorpion cat back
Forge dump valve
Filter
Performance torque stage 1 re-map

262bhp@flywheel and 292lb ft@flywheel

Peugeot 106 quiksilver with a 1.1 engine and an induction kit

forced induction* lol.

What spec engine was that 8v? :)

supersprint manifold
btb exhaust
catcams 708
kevlar procomp induction kit

un mapped

2001, 98bhp.

my vts spec in signature below
this was before i fitted saxsport and big filter for raceland
plus ther was no fan in front of car :(

will take it again soon :)

Saxo VTS 51
Standard - Running on 99RON.
Maha Rollers
136.9 hp (Fly - bullshit), 98.9 hp (Wheels), 108.6 lbft Torque.


Same car, same rollers
Differences are...
Raceland Mani, (a slightly leaky) Magnex centre section, Magnex backbox...
137.4 hp (Fly - still bullshit), 104.1 hp (Wheels), 114.6 lbft Torque.


So a raceland mani and a magnex cat back will give a VTS an extra 5 hp over standard.

38bhp transmission losses on the first run, and 33bhp on the second run? They're some pretty big losses for a FWD!

Only ones I have:

My old 172 that I owned last summer, made 180bhp and 162lb/ft Torque:


Mods:
Clio V6 Airbox
ITG Filter
JMS Matched Inlet Manifold
Ktec 2.5" Exhaust
Ktec Decat
RS Tuning Remap

God I really shouldn't have sold that car :n:

My Mk2 VTR made 111bhp and 120lb/ft Torque:


Mods:
Piper 4-1 Manifold
Piper Decat exhaust
BMC CDA Air filter

Exactly. tbh I only pay attention to the wheel figs these days.

This is my 1998 vts with Magnex twin box system & in-closed induction kit, was well happy. Now iv fitted a Janspeed 4-1 manifold (still has a cat) & superchips chip, will get it on the rollers soon to see the gains.

My VW T4 Caravelle 2.5tdi, it was on the local rolling road yesterday.. :)

114.6 ATW

Simota induction kit
Janspeed manifold
supersprint silenced center
Kamracing backbox
Cat Cams 743
Predator ECU

Mushroom style air filter
Standard manifold
Decat
Viper Custom made mild steel exhaust system with 3" backbox.

Was very happy with the result, the guy said it pulls very well and has good torque, not bad for 96k miles :D

Saxo VTS competely standard! not bad for a 12yr old car

If there's been no changes to the car it's interesting to see a 10hp difference from the NMS rollers to the Surrey ones. Especially considering some claim NMS are a hard roller to see power on.

I think if you got the WHP from northampton Motorsport then there would be less difference?


Btw I'll have a new graph to put up soon hopefully. got my forged engine in and the car will be remapped and boost upped soon :)

Wasn't it pauls old gti which made big power on their rollers without really anything done?

I've got a graph from mine had the map tweaked in August somewhere. Certainly made more than the 170 people said it would be after the high tranny losses from the maha's.

Paul with the china blue gti??
His car had cams iirc

Get your motor back together Ryan and get it back on the rollers

It is back together, map was tweaked in August. Although I'd like to see what it would do with more advanced ignition as its mapped for 95.

Yea get some good fuel in there.. Will make a difference in an engine as tuned as yours.

Found the one from August.

Mapped and run on 95Ron.

Yea i need to grab the WHP graph from NMS when i can..... Chris made 278ish at NMS on the same roller as me and again on the surrey RR made 240odd. The surrey road read alot lower than the NMS one.

Shows how much the rollers can vary really.

I know JKM the operator said it was a hard roller to get good power on, it made more than it did on dave walkers when it was first mapped so all good.

produced 132bhp at surrey rolling road

241bhp at the fly and 215bhp reaching the road, but of course 4wd so I can use all that power easily!
Been back since and will post up of more powerrr.

Updated my first post, i grabbed my WHP graph from NMS today.

The superflow dyno at NMS made more BHP & WHP but less LB/FT and also intrestingly the superflow is the only one ive used that calculates the run down for each individual car and this was less than the DynoDynamics used at surrey & RS tuning, so in reality the BHP figures from both dyno dynamics should be a little lower than they are.

Lowering the dyno dynamics ones would make the NMS figure seem even higher next to them. The run downs are not 100% accurate though as we know from various runs with maha's etc seeing a 2-3% difference shows the perceived calculations to not be a long way off at least.

Yea you cant really take any figure whp/bhp/tloss from any single one of them. im hopefully going to try and get it on 2-3 other different types of dyno's and see what readings come up.
