Hiya guys
as in the title really, cant ask the man who designed this as he got kidnapped by martians or some other reason for his disappearance.
I need to know what boost this setup makes?
im guessing its the 15psi the map sensor could cope with- but have a feeling it may be more. obviously im only appealing to about 6 others who have this setup as there rocking horse sh1t

if you are having it mapped - i'd put a big map sensor in just incase
-
doesn't seem to make much sense to me to not go for more than 1 bar, otherwise why bother with the eaton at all? It's going to depend what size pulley you have, imagine beavis used various ones depending on what the person wanted at the time.
-
why go for the eaton? ermmm it looked good :-S as silly as that answer is it's the truth.
iv got photos of 2 kits and I have mine and the pulleys are all the same size hayesey. i just ordered the kit - there was no options or anything like that.
just heard back from giorgio he is running a BVH and it's 11psi on the gauge. it's got to be a bar!
-
BUMP
ANyone want to shed some light on these kits? or does anyone have a chip with a map on?
-
i made my own kit and it ran well over a bar i know that dosent help much though.
-
i had my old AWT kit running over 1bar - but i just cant guess or my engine will go bang.
Shows what happens when you put trust in a company and get shafted
-
best bet is to measure the crank pulley and the charger pulley and see if the sizes (or at least the charger rpm/engine rpm) are the same as anyone else with an eaton kit fitted. Or at least this will tell you if yours will make more or less boost than Lance's or whoever else can post up their measurements.
-
well my crank i believe is a standard PSD toothie 1. it has 53 teeth. and the charger pulley has 24 teeth.
i have just been in touch with "LregG" and he says his was running 19psi with a 51mm throttle.
i have just gone over some old photos and he has 24 teeth on his charger pulley by the looks of it.
i have asked him for a couple of photos to confirm this.
EDIT! - just found this on Club polo - someone called milgo was selling it
(http://i79.photobucket.com/albums/j136/milgo1/DSC00142.jpg)
its the same - after painstakingly counting them sodding teeth - 53 & 24
-
I have LregG's old eaton kit ;)
-
Wanna sell? ;D
-
I have LregG's old eaton kit ;)
WHAT CHIP!!!! mate - the whole reason im trying to find this out is because i cannot find any information on the map/ spec etc etc
PM'ing you now mate
-
Just get it custom mapped with G60 injectors and see how it goes
-
if only it was that simple mate!
-
i have a home brew eaton kit with a psd toothed supercharger pully and it runs around 19-20 psi with a 51mm throttle body.
-
how many teeth on the pulleys mate?
-
if only it was that simple mate!
Why isn't it? You know you can run abit more boost than 1 bar on the standard mapsensor right? I have mapped 16vT's with G60 digifant running 1,4 bar (20 psi)
-
mine is the smaller pully with 24 teeth
-

No doubt- but to have any resolution in the map the 200kPa sensor is only good for 1bar. Also by running above this you'll be streaching the diaphram too...
Basically don't be a pikey for the sake of a £35 sensor ;)
-
mine is the smaller pully with 24 teeth
so really i am looking at 19psi arnt i!

well i had a rallye that had a 250kPa map sensor in standard so it could run 20psi - i have a 200kPa so i know it wont!
yoof - pm'd

this with an eaton cam mate?
-
no its with the standard cam, i have an eaton cam but it wont run right in my engine so i have had to take it out
steve
-

steve
well i have been talking to andy about mapping this and he is suggesting that i go back to the standard cam for getting it through an MOT, before he can map it properly. i am tempted to do this now. Mr Pitt truely left me up sh1t creak without a paddle - WHAT A WASTE OF MONEY!
-
Mines got the 1341 eaton cam in and it got through a MOT just fine. No problems with the emissions whatsoever and it was running like a right bag of nails!
-
does anyone know what the differences are between the 1272 eaton cam and the 1341 eaton cam? is it stamped on the end?? would a 1341 cam run in a 1272 engine and vice versa??? im wondering if i have a 1341 cam and thats why it wont run in my car. is their any marks on the 1341 that aint on the 1272 cam.
also i spoke to steve pit about my cam just after they stopped trading and he said the cylinder pressures with the standard cam are silly high thats why they made the eaton cam. i dont know how much of that is true but he had no reason to lie to me
steven
-
The 1272 eaton cam that i sent to Robin had no markings on it iirc. I'm not sure if the 1341 item did either :???:
-
the no marking '1272 eaton' cam u sold me jon was a 1341 g40 cam
-

But yours is a '91 car Jon, and doesn't have to sit the catalyst emissions test - so the limits are much wider than for later cars.

yes he said is was allowing overlap - so the boost was momentarily skimming over the psitons to help reduce some of the pressure and cool the cylinder down by pushing the hot air out. well thats what he said to me anyway - but he said a lot of things
-
the no marking '1272 eaton' cam u sold me jon was a 1341 g40 cam
News to me. I could only tell you what i knew.
-
well im thinking this is going to be 15psi with my eaton cam in it.
need to get this thing moving now as its taking the piss.
so im going to get a SNS eaton chip and see if i can get it through an mot.
ive half thought about chopping it in for a turbo
-
I thought about ripping all mine out and going turbo but its nearly there.
Anymore info on these sns eaton chips?
Did you get the other ones i sent?
-
nah, I translated a german page where the guy had an eaton and his chip was sns. but a dead end. I got your chips dood :-) going to try them today. fingers crossed.
oh and one more question to the masses. - dug out my PSD Newman cam box and it has "p2" g40 camshaft - I assume this is correct as the eaton one?
-
I brought a P2 cam for my eaton set up and was told it was the eaton spec cam. It's hard though to find out though the exact specs of anyhting PSD as you'll probs know. Your car is looking pretty sweet, I should have my eaton set up running soon i've got a psd eaton kit too so I'm too wondering what sort of pressure it will be running etc.
-
good luck getting a map lol
-
;) already sorted
-
how did you sort it?
dont matter chap, ive had enough of being a pikey - im sorting a trailer and its going to be done properly on a set of rollers or il never see this car finished. patience ran out
-
yeah, i'm interested in where you got a chip from too ;)
-
Replied to your PM Kieran.
-
i had mine AWT kit running on 55mm pulley at 1.3-1.4 bar
i had a custom map for it but it went with the car. i left it in the glovebox by accident
-
mine get a MAP reading of 14psi
-
thats more like it giorgio:-) happy days!
so mine should be 14-15psi like i initially thought.
praying to god andy will be able to come and have a look at this soon. my fingers are so tightly crossed
-
your assumptions should be about right. I have a PSD super-wicked-sick flowed head so that explains the pressure drop
-
mine was running the PSD head aswel
-
Mine is a BVH *willy waving*
20psi seems relatively high. What sort of readings are the turbo boys running?
-
21psi on my rr printout from john sleath, with a slight peak at 21.5 when the turbo spools up and the wastegate opens:

That power plot is at the wheels, was 194 at the flywheel.

Bet its for a 1272 tho ? :(
-
it was for a 1308cc

these Eaton kits have a massive problem trashing belts which i think i found the problem for. this is for you vwmk3jon
the charger doesnt fit flush to the charger bracket, to bolt it up you need to use shims. if you dont the 0.8mm-/+ gap that you pull in when you tighten the bolt up will put the charger pulley out of line and cause big problems for the belt.
heres the photo i said i would post to help you
(http://www.youngprodigys.com/randoms/Photo%20215%20(Small).jpg)
as you can see thats a large gap! - i found the problem doing a mock up fit on my engine stand.
-
i stripped 1 belt with the eaton kit. if they run out of line they dont last long. yep that chip was for a lightened and balanced 1308cc bottom end, PSD BVH, PSD eaton cam, aquamist and an eaton charger with 55mm pulley. deffo had 1.4-1.5 bar on the gauge but it was totally different power delivery where the g-lader used to make the boost pressure go straight to 1 bar and eventually drop but the eaton was low pressure to start off and as the rpm increased the boost pressure would keep rising.
-
muchos grasious matey. I see what you were getting at the other day now. I've slightly undone the bottom bolt now to relieve some pressure and hope that it keeps the belt on. Shame i didnt know that the other day when i was in spacer making mode :lol: i'm sure theres roughly a 1cm gap between my charger and the bracket. time to hack up more wheelbrace :ninja:
-
don't use the car with that bolt undone mate. you need to measure the gap and use the shims I will send you if you pm me your address. 1cm? that seams a lot lol do you mean 1mm?
-
ive gotta go out in a bit and check things ready for a silly misson tomorrow so i'll measure it. its less than 1cm. guessing 4/5mm but its definately more than 1mm!!!
-
I am working stupid hours as some retard has become a great fan of binning his car at every GP so have not really got the time/motivation to write an explanation up in full but -
The psd bracket is pretty poor. the charger flexes about far too much.
Take your bonnet off and rev your car, its a scary sight
-
i can feel it occasionally :(
-
I agree the bracket could do with some more meat on it as it can flex- but you can take steps to stop this. if you look at your rear bracket giorgio - that ain't going to do fook all to stop it moving! that just holds the charger up at the back. what I have come up with uses the hole which goes right thro the charger under the charger inlet. it bolts solidly to that bracket on the exhaust and it's an important integrale part of holding the charger.
-
I'll get a pic of the epic gap on mine tomorrow but i can assure you its ALOT more than yours :( Must be 3 or 4 threads of a bolt.
-
so imagine how much out of line that must be getting when youve done the bolt up - no wonder your shagging belts quick
-
Strangely when i got it there was a 2mm wedge tacked onto the right side of the mount on the charger ???
-
photo please
-
Not the greatest pic but i'll get another one when it decides to stop raining and brightens up abit.....................

going to need a better photo mate - i simply cant see anything of the bit i want to look at!
-
Crappy iphone camera ftl :( I'll grab a torch and try again :)
-
(http://i965.photobucket.com/albums/ae140/jonjong40/IMG_0396.jpg)
Any better?
-
so your telling me you just tightened that bolt up until it got tight?
-
Nah, its nipped up.
-
NO! i mean - do you do the bolt up until that gap disappears?
-
no. Belts still on with it like that plus wouldnt it be pulling the charger out of line?
-
yes doing that bolt up would put the charger on the piss. BUT that bolt has to be tight!!! that's what holds the charger still and stops it moving and vibrating. if you drive round without that bolt tight then no wonder your belts arnt lasting long. I'd expect your pulley to be worn aswell.
I'd make up a plate to remove most of that gap and use the shims I'm sending to you 2moro to get the gap to zero
-
i'll have a look and see whats laying around at work tomorrow ;)
