seems a wide range of results there although no-one seemed happy with what they got (except for me - i expected to be calling the AA!)
-
i was very happy what i got.
-
I was happy - 115 standard
-
Happy with my result- considering there's a few more PSI to be had and my aquamist wasn't working :-[
:)
-
by the way, just in case no one heard me shouting it but jez's fiat made less than stock power :D
-
oh, no one looked happy! Mustve been the weather?!
-
who was the chap filming most of the runs? Just wondered if he got one of mine? Wanna see it pop flames (I was busy shitting myself! Lol)
-
oh, no one looked happy! Mustve been the weather?!
well not sure, plenty of people seemed happy too. Maybe some have too high expectations? ;D
The reason jez's fiat coupe didn't make stock power was because his boost controller was going mental, the torque curve was like a saw-tooth shape as the boost was coming in and cutting out.
-
Nice results people :) I'm still so gutted about this and I'm still in a bad mood about it, and I really wanted to see Yoofs!
-
Was a really good meet, enjoyed chatting to everyone - cheers to pete, haysey and anyone else involved in the organisation - top lads.
Must admit I was a tad disappointed with my result, I was expecting more from my spangly new 1473, although I'm over the moon with the actual performance - so I guess numbers don't tell the whole story.
I guess I'm a victim of pub figures driving my own expectations - never had it done before so it was a bit of a stab in the dark. Pleased with my spirit level flat torque curve though...
If anybody can shed any light on how anyone can claim to have achieved 170+ bhp with a G40 'charger I'd be all ears, can't see what more I could possibly do!
Those turbo set ups were mightily impressive btw...
-
Did 167 hp in mine at 6932 rpm (limiter) and it had not peaked yet
Spec: Twin inlet charger (67mm), toothed belts, heavily ported charger, 49,5 mm throttle body, Ported GT inlet manifold, Jabba stg 2 head with custom 264/270 Newman cam, Supersprint 4-branch, race cat and Supersprint 2 inch exhaust. Custom mapping with G60 injectors from Jabba.
-
Where are the pics chaps!
-
Cheers for the reply, I should've mentioned my spec I suppose!
1473cc, BVH, Full blend, toothies, PSD front mount, Ported/Polished TB, Ported/matched GT inlet, PSD 4 branch/full system, red (310cc) injectors, Matched Newmann cam, Custom PSD map.
Surely I was right to expect more from my extra 200cc?
My boost gauge is showing 8psi with this spec, sound about right?
Any ideas welcomed people!
-
8psi is very low I'd say something is wrong there. Increased stroke does more for torque than bhp.
-
chatting this with andy, 8psi does seem low, even if everything is flowed to the max - maybe the charger isn't the best. Any chance of trying another or trying this on another car??
-
I was happy with my 137bhp with full blend charger, gt inlet, 65mm pulley, induction kit, heatshield, matching jabba spec chip and enlarged 'flame' spec exhaust.
Looking for my G60 chip so I can run my green injectors but it's been lost in the process of moving house :-(
-
8psi is very low - I was making 15psi with the same spec as you on a 1341cc bottom end with a healthy charger. It dropped to 12psi with a different worn one.
The 132cc extra swept volume you've got shouldn't restrict you to only 8psi - I'd have thought around 13psi would've been more like it.
Could be the charger, or could be something more simple like a boost leak?
Given your boost level I think the power was pretty good. Barney's old 1341cc G40 with everything done to it made 160bhp running stock (7psi ish) boost levels, so with the extra cc I reckon 167bhp is fair. His made over 190bhp at Aldon once it had a smaller pulley on it!
____________________________________________
Was pleased with my 165bhp @ 14psi, it'd made 175bhp @ 17psi at Emerald, so I think the numbers are about right.
Since fixing a leaking manifold/turbo my Emerald boost control map had completely gone to pot, so I pretty much ended up mashing some numbers in and hoping for the best.
Need some time on a dyno to bring my 'normal' map back up to 17psi and sort out my proper map for 21psi so I can keep up with Yoof...
-
Neowwwmm
21psi (no aquapiss/retarded ignition- hence the torque dip):
(http://img.photobucket.com/albums/v251/Young_Un/powercurve203bhp.jpg)
25bhp Hit of Nitrous:
(http://img.photobucket.com/albums/v251/Young_Un/powercurve223bhp.jpg)
Still a fresh turbo too and currently no dump valve (not had time yet, cardinal sin!!!)
Think with more refinement I can hit 230bhp with the nitrous, then I'll be happy. Hoping for 12 sec 1/4 next year... :D
-
very impressive figures yoof ...HOW THE FOOOOOK DO YOU CONTROL THAT... has it cost you a lot of mular to get that power
-
so yoof is yours that fastest G40 (ish) then?
you made good power there!!!
all good ill have to have a run down next year.
-
i was more than happy with mine 122 bhp and its only runnin a filter and cat bk exhaust and 123 thou on the clock ;D
-
kinda depends how you view the nitrous. Stu Baxter's car made 219bhp a few years ago with a similar-ish spec to yoof but with a G60 blower and no nitrous. Although it didn't have he same chassis mods as yoofs so I doubt it'd have been as fast on the road.
-
I know of quite a few in excess of 200bhp- as haysey said they're a similar spec to mine but with G60 Laders on.
1/4mile wise I've not heard of a FWD Mk3 Polo go quicker than 13.1 in the UK- unless someone can prove me wrong it's the fastest in that respect, with custom coilovers, Gripper LSD, Subframe & Wishbone Conversion I'd like to think it's one of the best handling ones out there too.
Cash wise to get it to this spec would cost in excess of £5k, I'm fortunate enough to have the skills and friends in good places to be able to do alot of things for less.
To be honest I enjoy driving (and ragging) more than anything else- as Haysey will verify!
-
yea thats the way i look at mine bhp figures are there for people with a small penis lol,
i just like to rag mine just wish i started out with just a GT now lol.
could of saved money there.
-
Hmm... Interesting. It was running about 11 or 12 psi when it was 1272 and standard head so seems i was down on boost before and the the drop following the rebuild seems about right.
Will have a good scout around for boost leaks but it does hold 8psi pretty solidly, failing that will swap my charger over with my mates R1 spec one and see what happens and report back.
Did PSD do two different sizes for the toothed belt kits? Maybe mine isn't the smallest one?
Cheers guys.
-
you should get 1 - 1.1 bar on a standard head/inlet etc. with a flowed charger and toothies. As far as i know they only came in 65mm size (well effectively spin the charger at a same rate as 65mm would)

I wrote a different user name down sorry as i wasnt actuly signed up. (g40poles)
I was also happy with my 153bhp result and it runs bout 15psi and im sure there a possibility of getting more out of it as im still running standard intercooler and injectors for a start!
I know that Dan Crebb witht the silver show car is running around 180bhp mark with G40 charger on so it is possible to get a good bhp figure with standard cc engine.

Im surprised with this...i couldnt make it this year but last time i ran at the g40 rolling road day i got 130bhp (obviously only 7bhp less) with only the following mods, de restricted air box, de cat, dewedged throttle body and full blend charger that's all...considering your mods i personally would of expected more? could be wrong like but if i put the things you have on top of my few mods, smaller pulley, chip, gt inlet, exhaust...i'd hope for more than a 7 bhp increase? strange that? and then i remember that year Sam made 125bhp with a ported charger only!...
anyways...some impressive figures popping up for sure...makes me want to modify one properly..
gutted i missed it to be honest..always next year though!

Have Beavis and Jonny tinkered with this build for you yet? That boost pressure does seem low for a full blend, you should be getting around the 14 psi mark with toothed pullies. On the bright side, once the boostage is upped, you will be hitting great power figures ;D
Shame i couldn't make it this year, looks like a good spread of results.
-
my charger needs servicing plus the plugs and leads need changing so I expected a figure in the 130's. Some of the results that came out were abit odd in my eyes.
-
HEY UP
THE RR MEET WAS SOUND, THANKS TO ALL INVOLVED
I THOUGHT WITH THE MODS THAT I HAVE DONE IT WOULD HAVE MADE A FEW MORE POWER PONIES,BUT WHAT THE HELL THAT MEANS THERE IS ROOM FOR IMPROVEMENT.
OVERALL I WAS NOT DISSAPOINTED WITH FIGURE 142BHP AT 6230RPM 140 Ibft TORQUE AT 4000RPM.
I WOULD PUT MY GRAPH ON BUT NOT SURE HOW TO DO IT,CAN ANYBODY HELP
-
sure you just have to scan it into your PC and then insert it ? Probably using the insert image button (bottom line above smilies, 2nd from left)
-
i saw alot of people with cameras and camcorders, any chance of getting some snaps up? :)
-
Sorry to hijack here :(
i was a at some polog40 RR day but unfortunatly not :(
i was just wondering if a could have some of guess's as to what power i could put out?
and wat i can maby do to ensure im gettin the most of all my mods ?
i currently am running
Ported and polished Cyl head
ported GT inlet manifold
Piper Fast road cam
G60 green Injectors
sns stage 5 chip
ta tecknix 4-2-1 manifold
PSD center and rear (63mm)
de-wedged throttle body
Toothed belt conversion (65mm)
thin metal headgasket
some new better quality coil
w5dpo plugs.. and the timing set up proper :L haha
plan to run Cossie fmic soon
the engines just had a head rebuilt with new oil seals and re-ground valves
it was skimmed but not dramaticly.
i dont want to shame myself by sayin some outragous power expectations but i was hoping for it to be pretty good.
-
i'd said 155-158.
-
ah, wat other things can a do to maby help get power up?
would heat wrappin exhuast aid cold air induction?
-
i'd said 155-158.
I have rolling roaded 167 on a "similar" spec engine with custom Jabba remap
-
wat the isn't so similar :)?
i would like to get a custom map but doesn't seem to be much demand for that up here?
i'd have to drive down to england to do so... (i might even ! :O)
