POOR DYNO RESULT 16v - Page 4 - Saxperience

johnnyg_vts · 24th September 2010, 15:18

if your car runs ok, pulls well and doesnt seem particularly slow then i wouldnt worry about a singular rolling road result with a million variables.

yep listen to the info... even with the cold air feed, the air filter will still draw some off the hot air in from the engine bay!!

unless it totally enclosed... i.e. bmc type or racland type ones, will work better to get no heat soak from the engine bay.

i have this one

simota. bought to fit a c2.

AndySAXO^p · 25th September 2010, 13:40

see that will work alot better than just an cold air feed.. with an open type filter.

5 weeks after this result i had a drive shaft joint give in. i do wonder if it was ill when i had the power run.

it could well of been strangling the rpm/wheel power...

ryanmt · 6th December 2010, 20:19

doubtful it would make any difference tbh

I don't like the fact dd's guess the flywheel figure. Was it on the right settings? My friend has a 16v with 4-2-1 and filter etc and made similar results to you on dd's. After changing the filter to a different type whilst still strapped on the power jumped up to 130ish. Just like you he thought that it was fine before and that there was no problems.

flywheel figure is always a sort of guess ,as all any dyno can do is measure power at wheels --the fly figure is a calculation of some sort--how accurate is the guessing bit
as a guide most saxo ma g/boxs take around 23-26bhp i

since then i threw the airfilter i had on it as it was restricting my car instead of gaining

loudandproud205 · 8th December 2010, 23:53

people forget that mass area of an open filter over enclosed.

Stu i threw that simota set up in the in and went with an ecosse green set up on my saxo, increased across the full rev range and was so much better to drive.

oh and if sucking hot in was that much of an issue all of the itb boys have wasted there money then as the inlet is on the wrong side and well its either cut the scuttle panel for stale cool air or warm air under the bonnet.

after all rickyp proved that a single inlet could still make the 'high bhp figures'

moxy89 · 9th December 2010, 09:42

take the results with a pinch of salt mate, normal they a loads of rubbish anyway, you could go to another rolling road and get 150bhp, ie the rolling road at french car show people where making 140bhp with a mani and exhuast and 135lb of tq. Not going to happen.. take them with a pinch of salt if you car fast and keeps up with car on track power is nothing.

AndySAXO^p · 9th December 2010, 10:10

Hmm Rickyrpm uses chipwazard which gives werid reading, I mean Willsy car made 163 and then a saw a car for sale on here with same sort of spec making 177 RR at chipwizard.

So that these cammed cars from chipwizard with 155-160 bhp figures, I think are more the normal 140-150 max bhp like most cammed vts.

moxy89 · 9th December 2010, 10:21

I would have thought a large majority of tuning companies will make there machines give higher reading, as people crave power, if they get a massive increase there going to go back. They take it on another rolling road and bang. 15-20bhp less and that a more accurate figure

AndySAXO^p · 9th December 2010, 10:58

Well TDF and NMS gave me basically the same figures at racing also gave same reading as NMS when a mate went there after going NMS, all them gave same sort figures.

Same as these mobile dyno at shows they give out high figures so it get around and they get more people paying on the day!!

I got a saxo vtr 2000 and it ran 109.4hp @5800 and 112lb/ft torque@5000, but its probably the just a dodgy rr. The best one i've been too is torque of the devil in uxbridge.

jeppy24 · 10th December 2010, 11:07

you've got to watch out for happy dynos!

tommy_g666 · 24th December 2010, 12:11

I had mine rolling roaded at srmc in leicester.

I have the later vtr engine in and made 100.3bhp (fly) and 132 torque. At the time i had a bmc open without cold air feed, 1.4 furio gearbox (came with car), saxsport 2" race system and miltek 4-2-1. I was well happy about the torque figure but i was hoping for alittle more bhp. My gearbox is shit and has cheap crap oil in. I have now fitted a cold air feed to the n/s morette straight to the bmc. I'm also going to be fitting my cb90 rallye gearbox and good quality correct grade oil in soon and going to get it rolling roaded again to see the difference.

Ellisg93 · 24th December 2010, 12:33

I'd love to get my 1.1 on a RR

Jokes. It's gunna be a VTS soon

AndySAXO^p · 24th December 2010, 13:17

yer remember that torque is in NM not lb ft ok it about 97 lb ft torque. so that about on book figures so would say you should be happy take into account that it not a new engine, would be happy with that.
