Im now confused, are the good or bad lol.
What ecu setup is best for running them? Do the linkages etc come with the kit?
About 16%..
With Jenvey 45mm parallel you see about 20% on an F7R.
Would be nice to do some proper controlled tests back to back, would a be alot fairer comparison.
Paul - again thanks for the support It's appreciated.
and what gains did you see lower down the rev ranges?I'll get some graphs up soon but because i changed dyno's i can't overlay the previous graph from the stock inlet, i am sure Ronee has one she can scan though.
Previous was 198hp and with the new bodies from AT it does 230.
Fantastic gain IMO.
Apart from fmp's experience all the other systems we have made, have done exactly what they should have done. We have sold plenty of F4R/F7R sets, and not had another person come back saying they didn't perform. One engine tuner in france has bought about 5 sets on repeat orders, and has asked for another only friday. I'm trying to track down as many people as possible to get their feedback on them - good or bad - to make sure they are performing properly. We have invested in new tapered designs for people to try, and I'm more than willing to listen to people's preferences and needs.
We are working closely with a local ECU manufacturer www.specialist-components.co.uk - Their Typhoon ECU is very advanced and can run things like BMW twin vanos etc. We have the ECU/ITB honda kit with them, and they are interested in a similar renault kit. Of course the throttles would work with any ECU, and RS Tuning are working on getting the standard ECU able to run the throttles (imagine the saving doing that).
The F4R throttles come as a complete kit with linkage, extentions, trumpets, o-rings, they will fit standard rail and injectors, standard 172 non DBW TPS and throttle cable, and have adaptors for people with air-conditioning to keep the A/C if they choose. Comes fully built from us.

Any chance of these working with stock ecu? I know paul was trying it a while ago but thought it was too much of a nightmare?
^you don't HAVE to use omex or emerald, there's LOADS out there for various budgets
its not rocket science to be honest, i'd go emerald, best bang for buck IMO
Thats what i thought, it seems simple enough to fit them.
Bolt on job done.
Its just the Ecu and sensors side of things i aint too clued up on
And who supplys Emarald Ecu's ?
And i've been reading on here that with some tb's you loose your coolant temperature sensor and have to tap out a hole for a new one
Just spoke to a friend of mine who will be running a Megasquirt ecu on his vauxhall c20xe.
Ive tried to find some info on this ecu but dont know where to start tbh. Anyone got any info/feedback on this ecu?

They're a bit like marmite. Some love em, some hate them. I've built one myself and used it. Wasn't really a fan, there are much better ECU's out there that are made to proper standards, in sealed boxes with proper software and support. Personally I don't think the money saved is worth not having a "proper" ecu running your expensive engine.
Yeah i managed to track down that forum but its all over the place imo. The info/feedback on it did seem to be controversial.
Sounds like a very reasonable priced set up tbh. I will be keeping an eye on this. I will be looking to purchase a tb set up come summer time.
there is a slight size difference on the head port (as the port has bin made a little bigger)but some say that can help stop gasses reversing up, if you know what I mean
Had a morning sorting all the extra vacum pipes and gas injector jets (my rally car run on LPG) all gone really well just drilled out the optional threaded holes and inserted some pipe fittings.
I really chuffed with how these throttle bodies are working out upto now.
Bottom end apart from ballenced and destressed is stock.you running a stock bottom end dude?
Cat cams 5502422 with wossner 12.6-1 compression ratio pistons.cool, what cams?
I'll see if Hutchie will take some on his phone tomorrow and put them up.Pics!

I have another engine on the build same speck but with bigger valves and going to try some different camshafts 5502551, which have more lift, but similer timing. When I get this other one built it will prob be as far as we can go without putting a steel crank in, which will be mega money I would think
Wow 9000 rpm thats impresive is that with standard valves as I have had mega probs with them when I had my sadev dog box, when over reving the engine by hitting the wrong gear:dapprove:Standard crank is fine for a naturaly aspirated engine making circa 290bhp and 9000RPM if well balanced. Arrows will do you a crank for reasonable money if needs be.
Cheers

doe's anybody make them?IIRC, you need solid lifters above 8000rpm, the hydro's start bouncing around over that lol.
