chris@torque of the devil

Yikes, thats a wrong un!, but in its day it was the tits (if that was to your taste)

but your 125 at the wheels was not on my dyno toby!, i absolutely love your car and think its awesome performance for a pre crosser, the 1/4 mile times are fantastic too! the standard pinto still made 102 bhp god, can't believe the dyno day was only a week ago!

well mate, you might see that 250 bhp after all one day Gaz!

we do install nitrous and even stock the gas mate, you obviously would need a direct port kit which would start at 75 bhp (or 60 bhp on my dyno ). to fit the system properly is fairly labour intensive because we would have to drill and tap the inlet manifold etc.

Honestly, i really don't know fella, maybe, maybe not, but there really are so many factors and variables to take into account, you have almost matched your engine dyno figure on a chassis dyno and you are happy with that and so would i be. chris

engine dyno's and chassis dyno's are great to optimise fuelling boost, cam timing and ignition, chassis dyno's score highly on seeing before and ater results from changing these parameters when the engine is IN THE CAR(where it ends up!), also a tuning session on my dyno is £90 per hour (plus vat) and usually takes 1-1.5 hrs depending on the car, that (i think) is a lot less then an engine dyno set up session and takes into account the inner wing being close to the trumpets, exhausts that bend all over the place to clear the axle, radiated heat in the engine bay, fuel temperature and so on.............factors not usually when present on the engine dyno, my dyno corrects for relative humidity, barometric pressure and inlet temperatures, if other dyno's are not inputting this information how can anyone assume they are correct? The dyno dynamics dyno's do not guestimate the transmission losses on overun, transmission losses should be measured when the engine is under power not when the clutch is pushed down after the power pull like other dyno's. the figures that dyno dynamics come up with are more true to life in my opinion, they tested many many different engines using an engine dyno first then with transmissions attached to it and axles/props etc and measured the the torque at each step of the way to give the closest power/torque figures they could to "flywheel" figures. page 79 of jan 2008 issue of performance ford details how dyno dynamics collated this information.

adding to the crap, peak dyno figures are all about how big ya willie is my dyno just reads a couple of inches less than others

cheers fella, i'm sure im not hated either lol, but people will always believe the higher figure, its natural, Boxxer for one has just said he always going to go to one of the dynos that showed the higher figure for future comparison, yes it may be close to the engine dyno figure but that does not mean that it is repeatable on a different day or for other mods, its true, you should always stick to one chassis dyno, that way you can see the results of improvements hopefully. Thank you Jo for the compliment too

indeed! looks like the thread has gone to piss, as i thought it would I dont think "gone to piss" is an appropriate thing to call it, its interesting reading with different views on things, i'm new here i dont want to be hated in my first week on OSF just because of some numbers!

you have done no wrong steve, as i said, its a great exersise to do these comparisons, obviously because my dyno came up with the lowest figure of all (on a different day unfortunately) i'm more than interested.

seconded, known him a while now and agree fully. for the record steves own ford mondeo has been run on our dyno, a couple of BHP down on what ford claim but not much considering its not brand new. Was it not 20-25hp down or something on a 60k engine? er no it was not, i can post the graph up tomorrow if steve does not have it, who on earth told you that? must have heard wrongly then! you did indeed, i will pull up the graph tomorrow

you can edit wiki?, lol, excellent, in that case a standard pinto makes 102 bhp and 117 lbs/ft with no air filter and ashley system

Where was it run last, and what did you get? was at TOTD on saturday, the silver 4 door mk2 and ran 102 bhp and 117lb of torque, only mods are an ashley system and no air filter ah yeah! that was cool! So whats the std rating on a pinto then? taken from wikipedia......... 2.0 EAO The 2.0 L (1993 cm³) EAO was used in many vehicles from the early 1970s. Bore was 90.8 mm (3.57 in) and stroke was 76.9 mm (3.03 in). The 1971 Pinto and Capri used this engine with a single Weber 32/36 DFAV carburetor and 8.2:1 compression. In this application, it produced 64 kW (86 hp) and 140 N·m (103 ft·lbf). The engine was produced in Cologne, Germany. Output in the Escort RS2000 was 82 kW (110 hp) and 161 N·m (119 ft·lbf).

mate, dont get the hump! it WAS NOT about slagging off people's dyno's, and more about WHO's dyno was most accurate to MY engine on HT's dyno. Your not gunna lose any customers unless your insecure about it! You saying about the Fietsa ST reminded me of something actually...... I went to a RR day @ Motorworx about 4 months ago, and there was a BOG STANDARD, brand new, st150 on the rollers, it made 149hp. Now, the same day, my cossie made 350hp and 390lbs of torque, BUT, on sunday my cossie made 338 on yours, so i dont get why that would be different, but the ST 150 the same. like i said at the start, dont turn this post into a slagging contest, cos i'll have it deleted and start again Hey you got me all wrong there fella!, i understand that you are not slagging anyone off, but its not your dyno showing the lowest figures is it! I said from the outset well done for doing the test, its important that this stuff is shown because it can help everyone understand the limitations of chassis dyno's chris Deffo mate, and i wasnt having a go. ANY chassis is gunna be a guess at the end of the day, as its not directly bolted to the flywheel itself! i just now know who's rollers match up to my engine dyno figures, and thats who i'll use if i ever change anything. coincidently, i was speaking to Steve @ T n R, and he said all the engines that come off his engine dyno, then he fits straight into a car HIMSELF, read within a couple of HP of each other. Dunno whether thats true or not. Thats a fantastic comparisson, and is the best way to check the accuracy of a chassis dyno, wish i had an engine dyno too, maybe soon.

what i dont get is stuff like this, we ran a completely stock fiesta ST150 yesterday and it showed 149.7 bhp on my dyno, if that car was run on sanspeeds rollers would it show 161 bhp?, also the wheel figure from sanspeed and track and road is showing as 163 ish and we showed it as 145, huge difference there, i really dont know what to believe, my money is on the track and road dyno being 100% spot on and mine being a load of expensive red and blue shite, i give up and am now going to become a male stripper.

well there goes all my customers! :mrgreen: , fair play for doing it fella, not wanting to get all technical but a few things to comment on. our dyno is not the same as motorwork's, similar but ours has twin retarder rear set up, also the intake air temps were higher and the tyre pressures were different, we set all cars at 50 psi on sat for consistency, but only 5 bhp adrift and run on a different day, you should have come back to me for a freebie on the same day., the place that gave you a power figure with no torque figure WTF power is a calculation of torque and speed so why no torque?. thing is who is to say that if it went back on aarons dyno it would still be the same, we will never know i guess, well done for doing the testing though, its nice to see someone making the effort to compare. chris

Just wondered, have contemplated using it when (more like "if" i get time)my new engine gets built, just wondered if any of you guys are using it already.

Think he just fancied a beer mate!

Yes Toby, i believe thats what it does!, although that was based on the flywheel torque figure.

The thing is getting the air filter to fit cost me lots of time and money because i had to get spacers made so the backplate missed the fuel injectors , then i tried about 3 different combinations of air boxes/filters etc and after all that grief it's lost me lots of power . I wish i hadn't bothered now but i would really like an air filter on the engine in an ideal world Here's the dyno plot from last month which was recorded without the air filter fitted . that's great figues gaz just done a bit of vintage maths on your cars graph gary based on torque. torque x rpm ----------------- 5252 so..... on your graph at the peak power rpm of 7100 you made 158 lbs/ft torque, divided by 5252 equals 213.59 bhp, so 1 bhp adrift!

well said Steve, people certainly dont come to me for high figures, but i would like to think they are among the most accurate available, if i suspect them to be wrong i will be calling dyno dynamics - its still in warranty!!!!

they recommend warm soapy water
