I can recommend Hozelock's auto watering system - works a treat for giving a fine misting spray over the flower-pots and comes with an adjustable timer! :lol:
I'm just here for the gasoline.

Hi Gt5
Sorry have been asleep for the last 2 weeks and only just caught up with your post. :D

I assume that the picture you post is the one of your engine? If it is, then you are doing very well to get 140rwhp, as you only have a standard exhaust manifold and apear to only have a standard intercooler. If you have engine modifications (cam, valves, pistons, modified metering head etc) for185, 210, or 240bhp then the correct manifold is an absolute must to liberate the power as is the intercooler, as without these your engine will be limited to about 175bhp and pushing it further will result in a large bang and a big puddle of oil.

Also T5's never perform very well on the RR, unless you cool blow from the front of the car, where the blow covers beyond the front of the car so that the intercooler gets its fair share as does the underside of the car. You also need to watch the engine bay temp on the RR, as although your water temp may look ok there is the possability that you will get massive build up of heat that will give you some very false bhp figures.

Suggest best way to ascertain T5 performance is by 0-60 and 0-100 etc if it feeels good, then leave it alone, if not satisfactory then find out what has truly been modied on the engine and compare to the normal mod path and remodify acordingly $$$$$$$$

225 bhp spec engine,built by JPR fitted with a larger then standard intercooler, head mods, cam ect ect.

Follow what your saying with the formula for getting extra power out of these engines, i was speaking to john price the other day and he reckons it should be pushing more then 140 rwhp, saying that, this was at 0.9 bar boost, everything was ok ish at 1.1 bar with the excetion of a misfire at the time which prevented get bhp figures at 1.1 bar, charge temps were high though, thats why i am considering water injection, Ill prob keep the boost at 1.1 bar or maybe a touch more :wink: depending?

Funny thing is the rolling road looks after another turbo 2 which as standard internals, turbo ect. but with a custom chargecooler and ecu and he is running nearly 2 bar :shock: he uses the car for comp. track days ect so it doest have a easy life. and its still holding together,

when i spoke to jp i also mentioned the need for liners and forged pistons ect, he reckons the standard internals will be ok if not holding boost for long periods.

Still it would be nice to have all the mods you mentioned, just need to rob a bank :)

nearly forgot, they had the big fan at the front of the car and a smaller one pointing into the open hatch, a nice thought as most rolling road operators wont bother with the rear fan.

still puting my hopes on water injection for that little extra.

Intresting, I was always in the belief that the exhaust manifold was an absolute must for going beyond 175 bhp, but if its a JP engine I am not going to argue with him :D

If though you are intrested in the E manifold, then you may want to try and aproach Quicksilver, I know they intend(ed) to replicate the factory original as they wanted to borrow mine to use as a pattern.

2 bar on a standard engine sounds terrifying, I would be holding my breath all the time waiting for the bang :D

As to the RR, if they pointed a fan into the engine bay you will have restricted air passage through the intercooler you need them to blow air under the car, from the front, so that the hot air gets 'dragged' out (as it does when you drive). It is very noticable in my car that if I sit still for any time with the engine hot then when you move off again the full performance does not return for a few seconds.

This is cured in the GTA with the installation of a Charge Cooler PLUS when on-boost the charge temp is about 30 degrees less than without a standard intake. You can really feel the difference.

Sounds interesting re- the manifolds made by Quicksilver;-)

Re the rolling road, the thought did x my mind, :? someone else did point out that the ideal set up with the fans would be using three fans :shock: one at the front, one pointing at the intercooler and one for the oil cooler? he reckoned that there was a marked increase in the bhp figures on the rollers with this fan set-up?

:) Nearly 2 bar, does sound frightning, think if it was mine i couldnt watch it boosting up on the rollers, at that boost. think i would be at least a couple of miles away :) sayint that though, maybe :? it shows that these engines are a lot stronger then we are led to believe? i did say maybe :)

Might be interested in a manifold though? what spec are they?

Snake oil probably. Look at the exhaust manifold on the C1J Renault 5 GT turbo, far worse, and people are getting over 250bhp with that...

I know JP has these 'tuning recipies' for the 5 Turbo and I see in this thread mentioning the cams, headwork, intercoooler etc...but no mention of the actual turbo. The exhaust housing size on it is 0.28 as standard, and the compressor is a 40 trim, very small and limits the unit to around 180bhp max. Has this been changed with all the other upgrades? Just because it is a 'T3' on a small engine, still doesnt mean it can keep up, flow and heat wise...

Funny you should mention the turbo Dave, that was somthing i was thinking? To drive the T2 it has the same characteristics as a standard GT Turbo (OK a bit faster :) ) but just as though it runs out of steam? The GTT thats here at the mo was just like it with the standard turbo, even running high boost it was though it ran out of steam after the initial push from the turbo , Bigger Turbo now and its a totally different animal, its :evil:

Agreed, just because its a 225 spec 'engine' doesnt mean the ancillaries can keep up.

If the turbo's only good for 170, then no matter what else you do to the engine, its not going to do any more...

sorry - nope

thats an salv sacco engine with reciepts!!! 6.75:1 compression, forged pistons, steel liners, cam ballanced bottom end etc etc

with a bigger turbo and 4:1 manifold! ;-)

and after going to 2 rr's down south (dynotek and power eng.) made 280bhp at the fly at 1.4-1.5bar!!
but now can't make anything near that up north

sorry but steve as i've said - your car is more like what JP said - i'd take that RR figure with a bloody big pinch of salt!!

:D Thought JP had replied with the user name :D didnt know that its a salv sacco engine :shock: they reckoned that it was a standard turbo ect :shock: oh well that puts the dampers on the efi ect for this year :cry: (Saying that i think its getting stripped down over the winter, the white car not mine i hope :wink: )

To be honest i would guess that the fly bhp is around the 180 bhp mark comparing it with darens gtt running 17psi modified t25, head, cam ect which might be doing 200 ish bhp, he is much!!!!!!!!faster :(

What confuses me though, is the power outputs of the gt turbos with very little in the way of internal mods :? running big boost and big bhp, whats the diference with the two regarding strength :?
