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.

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.

Im now confused, are the good or bad lol.

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.

What ecu setup is best for running them? Do the linkages etc come with the kit?

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.

Paul - again thanks for the support :) It's appreciated.

Let's not speculate. I know where my money would be :)

and what gains did you see lower down the rev ranges?

been honest i can't remember all the numbers but it gained plenty everywhere. Once i see both graphs again i will let you know.

Would you be interest in running my little clio up and seeing which trumpets work best straight or tappered Paul?

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?

Sorry to gatecrash here, i have a few questions :)

What would i need to run/fit these on a 2002 plate 172FF c/w Air Con and a Drive by Wire throttle ?

Am i right in saying that these kits come with everything ?

But i'd need to buy a Throttle Pedal from a scrapyard or dealer for a Ph1/Mk1 172 as they accept throttle cables ?
And a Throttle Position Sensor from a Ph1/Mk1 172 too ?

Plus would i need to get my hands on a Omex/Emarald etc Ecu to run them ?
Or would i get away using the standard Ecu map ?
Or would i need to get the standard Ecu mapped to run them as mentioned above ?

Also would i need to loose my slam panel and replace the standard bonnet catch with pins as the trumpets are too long to keep the standard slam panel and catch.

The more info the better and prices of a kit all in with the required parts needed would be great too ;)

Cheers

Richard

^you don't HAVE to use omex or emerald, there's LOADS out there for various budgets


Ok cheers Fred :)

Whats the best and cheapest if that makes sense ?

Its just a f**ker i live in Aberdeen where there are very little good estabilished rolling roads around :(

And i guess the throttle pedal and throttle position sensor from the Ph1 is just a straight swap ? :S

Or is that the throttle position sensor i see on the side of the tb's ?
 
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 :(

Its not just a case of bolting them on lol!

Theres lots of modifying to do, you need to tap into the boddies for the servo vac pipe, fit a new thermostat plate, fit a full loom into your existing loom etc etc the list go's on!!!

To answer a couple of questions:

RS Tuning are working on the standard ECU's working these throttles.

We are also looking into using the Typhoon ECU to replace the standard ECU on DBW cars. This ECU will be able to control the standard dash board clocks (so no need for another dash board).

If you car is DBW, you'll need a throttle pedal and cable. The ph1 options are fine (as well as the TPS sensor). There are a couple of brackets you need to remount the coils and the pedal inside the car. We can happily make those, and hopefully Activ will be sending us some information about the ones he made so we can replicate.

With our throttles you don't need to change the radiator, or cut the slam panel, or use bonnet pins, and you can still have a proper airbox (activ has proved this on his car). So you could be saving money on the radiator, the dash board, not hacking about your bonnet and still make the power.

I had a nice long chat to Activ on the phone about what he has been up to and there are already one or two things we can change to make the sets better (which we will). He tells me he has run 220bhp with his set up - with what sounds like no where near the engine build that fmp is using. He has stock bottom end for instance. I think we may be able to improve on that figure with some tweaking as well. I have to apologise to fmp again as obviously he has been messsed about, I still can't understand where 40bhp went with your engine.

Thanks,

John.

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.

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?

P.S. forgot to say that each inlet port has an 1/8bsp tapping in it that you can drill through to the bore and connect up brake servo or idle control valves etc if you choose.

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.

Thats about as good as it gets - which is why I recommend using a "proper" ecu with support and an actual company who makes the things.

Removed my old itb's tonight and matched up and loosly boled AT on and they fit great, throttle cable works fine 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

Activ made me aware of that. I spoke to a couple of people, and as you say some think it would help with torque, and not really affect the power - similar to how exhaust manifolds should be bigger than the exhaust port. I think we're gonna try making some that are bigger at the port, and match it, it might eek out another couple of horsepowers? We'll see anyway.

I'm glad they go on ok!

Thanks,

John.

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.

you mean you havent got them on yet :eek:

i would of had them on by now ;) running and road tested :D

good luck with your timing hahahahahahahahaha

Got the car running today with the AT bodies and upto now it is a lot crispper and smoother ,throttle response is very good and they look mint. Also have fitted clio 197 injectors and they fitted really well just made some small spacers so that they fit correctly. the spray pattern is a lot better and the inject more at top end so hopfully make a difference.

cool, what cams?
Cat cams 5502422 with wossner 12.6-1 compression ratio pistons.
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:(

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.

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:

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