It is a custom de-cat, 3 inch pipe all the way to the back box then 2.75 inch tail pipe to reduce boom. A company near me made it, Demand Engineering, it looks lovely and sounds just how I wanted it too.
Can you see your boost, do you know how much you have 4000, 5000, 6000 Your limit is 6200? Any video with acceleration?
Grand Espace weight is 1800kg Stock 0-100 about 11sec Mine about 8sec Stock 100-180 about 37 seconds Mine about 15sec Of course many will be surprised! Specially from a red light or on a highway 5 persons In a car and full load in a back on a vacations.
Interesting thread and a very nice Espace right there! Do we have official information on what are all the differences between the various different F4Rt iterations? Would be very useful to have a complete breakdown somewhere to see just what is what and maybe even why Renault chose to upgrade this and that part for the higher performance versions of the engine. Seeing as you can squeeze out 200+ hp from any F4Rt, it would be very interesting to know why Renault changed ao many parts for the RS variants for example (and which parts they did change).
I have breakdown all of f4rt engines and I know the difference between them and from which year and so. From engine with 9.5:0 I got 280hp on stock internals, From 9.0:1 engine 300-330hp stock internals, From 8.6:1 engine 400+ stock internals. F4rt forged 550+ Block and head are strong, depends what you put in them and do with it!
I don’t actually have that much info, it was late by the time we got it running properly, I will be going back to get the set up perfected soon.....but I may as well do that once I have the bigger turbo, intercooler, injectors & so on!
We will see how it will go for you, otherwise I can forged my espace, 90mm IC, cams, dp, full exhaust, 840cc, 19t billet to 400hp or td05h 20G to 500hp, and some more good stuff
Walbro 255L and on some others dw265. But you should decide how much hp you want to have and how much you can get! According to this to choose optimal turbo and injectors and fuel system for it.
With 14T 1.0bar comes at 2000revs, with this at 4000+revs. Until 4000 will you take a vacation? We will see how it will drive, when you are ready
I know, but I'm old so I like a bit of lag, it will remind me of my old 300hp Sierra Cosworth, nothing, nothing, nothing....Zoooooom!!!! Its a GTX3076, it looks bigger in the picture than it really is....a bit!! lol
You are 2 years older than me. 300hp can you have already with 14T turbo , that you have in Espace now.
Well we are still going, we've added Supertec Inconel valves and uprated springs while the engine is out this time, not sure why I didn't do that first time really but hey, done now. Still waiting for the exhaust manifold that should be here this week and now just trying to sort fuelling, going with 875cc injectors and a Bosch 044 then the question is to return or not to return......!!!
I bought once again an Espace and it was with a broken belts, all valves are cracked. But now it has ported head, 630cc, 15T. Middle exhaust 60mm, stock cat and all rest is stock :-)
Ha ha, awesome, I'm still battling away with mine....seems that the Supertech Valves now don't fit.....!!
I did this on my orange meg, just got a local engineering company to ream out the exhaust guides, it's only 0.5mm
Hmm, too small in diameter and too short....plus the guy has tested the stiffness and they don't actually appear to be any stiffer!!
Flynny You must have bought the wrong ones, the smaller diameter yes, but if you push them onto the valve seals they click on, there was a huge difference in the stiffness of the ones i fitted over the stock ones.
