Not sure really as it was all going on out of sight but things were moving, you could feel it through the wheel, i broke 3 engine mounts and the wheels kept moving back in the arch as the bushes through the wishbones moved.Originally Posted by Tony Walker
I figured that if I was going to build new mounts then it was an opertunity to strengthen the subframe and wishbones at the same time.
Wow, good stuff, man your a handy guy
Who painted the subframe for you, very nice job? I used a place in the team valley for mine, did the whole lot for about £100 if my memory serves.
**** hot work Ashy
Just read this thread from start to finish- wowser! Have you had it on the rolling road yet?
She made 402bhp mate.Quick update, big thanks to Scoff (EFI Parts) for spending all day Sunday mapping my car, what a top jobs he's done. Thanks mate.
****ting hell. That's unreal. You're a talented man!
Thanks
Are you taking it to nationals? If you are I'll bring some tissues
Yeah Deffo mate
Did you do all the fabricateing mate?
Yes
Very impressiveYes
All coming together now, spent a few hours today tidying up the interior whilst I wait for the snow to melt so I can take her out for the first run of 2013.....
Dash
New Seats...
Ready to go.....
Nial car is looking awesome so loving the new seats. What seats are they?
They look like the clio 200 recaros, think new megane has same style as well
Do love how the dash looks in that car, great work there
Looking good as always mate fingers crossed you have a good year of happy safe boosting ahead.
Thanks mate, i've got everything crossed cos I haven't had too much luck over the yearsLooking good as always mate fingers crossed you have a good year of happy safe boosting ahead.
They are the same but mine are from a Corsa VXR!They look like the clio 200 recaros, think new megane has same style as well
Do love how the dash looks in that car, great work there
Having had a buchers in person at this car at scoffs rr day last year it really is minty mint! The seats and dash really take the car out of the 80's and into the present day, ohh and of course the engine/power output
really is a fantastic bit of work
Love the flockead dash... Something i have thought about for my 172.
Great work ashy
This thing is going to go like a rocket. Blown away by it tbh.
Good move on the wheels ash,looks stacks better
lovely car mate!!
are those power figures on stock cams?
Thanks Al, needed to go to 16's so I could fit 205's for more grip...Good move on the wheels ash,looks stacks better
Yes thats correct, std 172 cams, standard timing with no VVT.
This is a great project
Well done for all that hard work it's clearly paid off
Hope to see it in the flesh if your at national day
Candidate for best 5 ever I reckon.
Candidate for best 5 ever I reckon.
Thanks but that's a big claim!
Good work as usual ashy!
excellent job
i was just wondering, how much boost pressure does it run mate?
21psi mate.
Ashy can I have intercourse with your car please
lol! lovely result mate!
have you done anything else to the engine?
how much difference do cams make on this set up?
are you running a t04e turbo?
the reason i ask ,and please dont take this the wrong way , but the f7p turbo lump in jp's made 370 bhp at 16.5psi, (t04b) and i would have thought the f4r being a bigger capacity, possibly better flowed head design, would have produced more
The engine is fully forged but other than that and APR bolts etc its std cams, std head (phase 1) slight overbore. Turbo is a GT3071R... I guess it depends on lots of things but at the end of the day its just a RR figure.have you done anything else to the engine?

i've been wondering that too but i guess it's everything together.
maybe he has a better manifold, he's using a uprated cam probably better timed in then the standard f4r's are.
isn't JP's head flowed too? down low you see the difference though, Ashy's produces more out of boost.
iirc Scoff mentioned JP's breaths really well...
is yours on standard cam timing Ashy?
Coley telt me have a look on here when I was talking the other day........i am amazed with the work you've done like fella.
Top class work.....take a bow
Amazing car. Really like what you did to strengthen the wishbones
JP's was an unusual example, but most of that can be explained by his cams and other work. Overlay the 2 plots and Ashy will have more in the midrange. Peak HP figures are just that, a peak figure. It doesn't tell us what's happening the rest of the time.
Ashy's is typical of what should happen at 1.5 bar from a standard engine. A standard F7P would not have done that.
PS looking again at ashy's plot I'd say some inlet cam advance would help to bring midrange up a bit more and make peak HP a bit lower down. Maybe a good thing if it's predominantly a road and track car.
Scoff,
Was going to pick your brains on the 225 vs 172 cams debate. Cant remeber what the spec of each is, but i have a set of both to choose from!
true ,but cant help but think jp's inlet/exhaust cams are no where near correct,his inlet is retarded by a long way! he only set up to cam cover marks, and when i dialled exact same cam set up on mine some three weeks later using dti etc, using the same cam marks as reference, inlet was showing 138 atdc , dialed in four times, and got pretty much the same results,give or take 1 degree, alright there could be variations in the cam grinds etc, and his head could be different height to mine, but i could'nt help but think his graph was way to flat in ther middle because of this?
and not knocking ashy's fantastic build here , but i would have thought ashy's gt3071r should be a lot more effecient flow wise , than the chin chong to4b of jp's, and produce much better results everywhere on the map per psi, they are both using very similar inlet manifold setups /runner lengths? and free flowing exhaust set ups, jp's head is megane f7r port matched to inlet and flowed, would it be that far away from a f4r head in standard form in performance? just trying to gauge how much of a difference there would be between the newer f4 and the older f7 engines thats all,
just read your entire build thread again ashy, great build
ps is the anti surge compressor needed on this set up?

Yes andy, all that retard in the inlet will flatten the middle and sometimes help hp at the top depending on what the overlap is like.
Think about it this way. A stock 172 makes between 164 abd 168hp on my dyno. Lets assume ashy's engine does the same without boost. Very cruedly speaking at 1.5 bar of boost we've got 2.5 times the air flow, so we get 2.5 times the power. 164 x 2.5 = 410hp. Of course nothing's 100% efficient like that so 400hp is exactly what I'd expect. You can't magic air flow out of thin air
In JP's case, to be able to make 370hp at 16psi we must be making in the order of 180hp without boost. Its more than I would have expected but not outside the realm of possibility. With the dyno we have the possibility of reading low if we're slipping wheels but absoloutely nothing that could ever make it read high, so something about his engine works very well
Not enough boost in either case to worry about an anti-surge shroud on those turbos.
Horses for corses matt, but if you're still planning on using that big turbo, you certainly don't want anything as poxy as a set of 225 camsScoff,

well, i'm not trying to prove anyone wrong or anything, or be ****tin on Ashy because the result is great in every way but:
there's a lad on cliosport who had a completely standard trophy, fitted rods, pistons and megane sparkplugs and a gt2871r on top.
this is the thread with result:
http://www.cliosport.net/forum/showt...oTrophy-update
he made 340lb/ft at 1.2bar and 374 peak hp. Ashy's powerband is obviously alot flatter/ smoother/ broader but this does show there could be had more torque/power with this boost level..
then again, it isn't rolled on the same rollers so there could be a difference in that ofcourse, i don't know how legit the RStuning rollers are??
for Matt:
Tutuur, thats Steves car. It's a fantastic result from only 1.2 bar. I don't think we'd see that power on my dyno at 1.2 bar. 1.3 bar might do it. So it also depends on how accurate people are with their boost figures. It might have been 1.28 bar for example. That alone would just about explain it. Or maybe the average was 370hp and his dyno recorded a peak of 374. I always filter final results to show an avarage rather than a spurious spike. There's lots of explanations.
Ashy's power output was just fine and right where I'd expect it to be at 1.5 bar.
My memory also tells me we did that with 95 ron. Ashy will confirm. Another 10hp might have been possible with extra octane.
yes, Steve it is indeed.
however when you look in his thread you'll see you're right about the peak. it's only a peak of 374 where 500rpm earlier and later it's 'only' 360bhp.
ron 95 might explain a thing or 2 indeed. as mentioned before, the result is great in every way but improvement is always possible as you off the most would know
how much timing does 95 differ to 98 on the knock limit? i understand it's guessing but in your experience whats the trend?
