Leicester RR Day - Interesting results......

[Ian Geary]

Yep, I'd like to say thanks to Jo for putting the effort in organising this event.

I'm pretty chuffed with my results: 247bh/p at 6615rpm, and 319Nm (235 ft-lb) of torque is pretty good from my rev3 with filter and zorst.

Altho my power figures were fairly accurate... the dyno plot reads a different story... check this out...

Jonno, here you go mate, a pic of the graphs... (click pics for bigger versions)

[Blaze]

What a good day thanks to Jo and it was good to meet you guy's as this was my 1st outing with IMOC .

i also had a slight over fueling problem but managed a 265.3bhp @ 368.4nm of torque

[Sidewinder]

What are people's drivetrain losses ('Drag power') like? Looking at Olly's sheet on here shows 62 horses, whilst mine sits at 53. Just curious to know the averages to see if my Phoenix Power gearbox is nice and efficient or there's something else to it.

[redeye32uk]

What a great day, so many different results?
Thanks Jo for all the work you put in =D>
I was well pleased with my 266.2BHP @ 6370 revs and 325.6 Nm (240.2lbft) @4310 revs looks like a shopping list acomming, need more power
Anyone got a pic of me an tim sitting in the back of my tubby while on the roller? Like a copy plz if you have.
My drag was 61.5bhp

[un1eash]

It was a great day although abit cold. Very pleased with my mk1's result 115.5bhp at 6855 rpm and 132.3 Nm. My car is completly standard and was the second highest for a mk1. The highest was 119bhp and that only had a performance exhaust.

All the other mk1's had performance exhausts and air filters and were getting between 105-113, if i remember correct.

Will have to see what fitting my KnN will do now, could make a lose

[jimGTS]

My results were poo, 222bhp at 5165rpm with massive overfueling at 5000rpm.
But i got 245ftlbs of torque at 2640rpm ??? WTF?!?!?

Very peeeeed off but nevermind, just got to spend more money i suppose.



DannyW

was this at the wheels mate??????
we got very similar mods from what i remember......

[Sidewinder]

It'll be interesting if everyone from yesterday puts down their RR results on this thread for comparison. I'm still interested in the drivetrain losses, so that would be useful to know too.

Anyone wanna buy a Unichip with boost module (not yet fitted)?

[GazMR2GTS]

Well it certainly was an interesting day for me

First run he did the engine management light came on, and no boost kicking in so decided to take it off the rollers as it acheived an awesome 65bhp lmao, Thanks to Tim and the guys that came to look, and again to tim for some brilliant advice, im a novice to turbo's so now i know a bit more about them. Anyway with tim's advice i took off my boost controller which inadvertadly was installed the wrong way round lmao, and run it at stock, Still something majorly wrong with it though as second run it reached 160bhp, which is seriously wrong for a rev2 as standard there 220ish. So im now looking for a decent garage to tell me whats wrong,i guess at a boost leak somewhere, and with the manifold blowing, could be part of my problem. Other than that im at a loss.

In whole a dissapointing figure, but such a great day to see some of the nicest MR2's iv seen in a while, Nice to meet some of you off here too, and generaly a good day.Thanks jo.

From the figures I can see in this thread, here is just a quick table of figures in numerical BHP order

REV3 Turbos

294.0bhp - Dangerous
266.2bhp - redeye32uk
265.3bhp - Blaze
247.0bhp - Ian Geary
246.0bhp - Nige
243.9bhp - Import
242.5bhp - the did

REV2 Turbos

222.0bhp - Danny W

[MikeyG]

Yep - First off thanks very much Jo for organising. Twas a great day although I had to leave a little early

Anyway I was happy with my results. I have only had the car two months and it is fairly standard. Its a rev3 with Apexi N1 muffler, Aussie downpipe and HKS panel filer. My figures were :-

254.5 bhp / 325.6 Nm torque

I least I know it must be quite healty and ready for the EBC to go on next weekend for a couple more PSI.

Thanks to everyone that came, glad most of you enjoyed it

It is my plan to run this as an annual (november) MR2 MK1 club event, maybe changing location to suit different people, unless this will be a pain for those who want to make direct comparisons with their last run.

I will have all the results soon, so if everyone is happy i can post them up when i get them. I was the lowest! (again )
I think its interesting that some of you were not happy with the figures, as a lot of the MK1's seemed about right (considering age of the cars - only a few brake down from std or spot on), and a few of the standard MK2's were bang on what they should have been too, ah-well......
It will always be an interesting debate
anyway - i'm sure mine was under by at least 30 BHP! LOL

Looking forward to reading what JTuner does for us, and will let you know when i find out what issue it will be in.

We did eventually make it to a pub for some grub (about 12 of us, then were joined by Gordon and Emma from streetracers also)

Hope you all go home ok, and see you all at the next event i do:

Rotorstock

Thanks again
Jo

last again!!!

My loss was 54bhp! Does the weight of the wheels and or tyre widths make a difference. My alloys are light weight jap jobbies

[Ian Geary]

my drag loss was 60bh/p at max revs, and that's with new gearbox oil this year.

Not being pedantic or anything, but my engine bh/p was actually 254bh/p - I quoted the "corrected" figure of 247bh/p for some reason. Anyone know why the difference?

Ian

[Import]

Same here Ian - my "Engine Power" was 251bhp, but corrected down to 243bhp

[kevin..in]

Hi guys can I appologise to the MK2 owners who I didn't get to speak to at all due to me trying to obtain as much info from MK1 owners do do a bit of a report for the MK1 Club mag. The thing I didn't get though was forum user names so apart from system-g and mr2mk1chick I cant put real names and forum names together if you see what I mean so could all MK1 runners let me know who you are/were please

[jimGTS]

FROM THE PICS ON THE OTHER THREAD GUYS I DIDNT SEE NO SECOND FAN ON THE IC!!!?????????

mind you the SE RR was ic fan only........
suppose it doesnt really matter, but id still does prove the the rev3+ tubbies hitting 240 ish fly........
what you guys hit at the wheels tho???????

TO MANY ARE QUOTEING FLYWHEEL!!!

wheel hp is the real all round figure, and is comparable to other RR from around the land.........

seemed a great dad guys/girls, bu looked COLD!!! lol!!
both our RRs was 20 degess + C!!

[jimGTS]

pps, you saying the wheel power loss was roughly 50-60bhp????????

ie, at the wheels you was hitting 180-200, but flywheel you was hitting 240-260????????

weight has nothing to do with it IMHO, weight of the wheels anyway, geez, im sure the 0-10kg in difference in wheels doesnt matter to much considering you have over half a ton on the rear wheels anyway!

[DannyW]

My results were poo, 222bhp at 5165rpm with massive overfueling at 5000rpm.
But i got 245ftlbs of torque at 2640rpm ??? WTF?!?!?

Very peeeeed off but nevermind, just got to spend more money i suppose.



DannyW

was this at the wheels mate??????
we got very similar mods from what i remember......

Flywheel mate, i know it's poo-poo-Ka-Kaaaa aint it. the graph tells it all, everything just drops at exactly 5000rpm. too much fuel. boost was holding fine though.

[Sidewinder]

FROM THE PICS ON THE OTHER THREAD GUYS I DIDNT SEE NO SECOND FAN ON THE IC!!!?????????

Yes, I thought along similar lines. A nice big blowing thing at the IC would've been nice (and raised the figures a wee bit too! )

what you guys hit at the wheels tho???????

I hit 200.3 BHP at the wheels.

TO MANY ARE QUOTEING FLYWHEEL!!!

Indeed - the figures I've quoted earlier in this thread have been the corrected ones, but agree that ATW figures are more usable.
