G-Day Willie, Congrats on this very nice dyno results and super healty g/s logs.
I am about to take the plunge and go hyrid as i have done all the stage 2 mods i can and cannot get her over the 280bhp.

Did you put in new rods/injectors to accomodate the hybrid or a high flow mani?

Thanks

Hi mate the unos MBC is on the forge website and an excellent highly recommended piece of kit.
Desecreening the maff is a recommended mod to do if you have a spare maff tube handy. The mesh pulls out easily on one end and has to be helped out at the other. Descreening removes alot of restriction from the intake which allows more air flow. If using a decent cone filter the air is being directed correctly and laminated by the manner in which it is sucked into the cone at right angles does the same job as the original Maff screening.

Cheers for that

Never spotted the Unos before, don't think it comes up if you filter it to the Mk1 Leon on the Forge website. Not mapped my car yet but will bear it in mind when the time comes.

Re. descreening the MAF, can I safely swap my MAF between housings? Thought I read something that they were matched (or calibrated) to the housing they're in?

No there not. If you run a LCR housing, it's 3" which ever housing you use/swap around

I made around a 10g/s improvement when I descreened the maf, nice little mod although it's been debated quite a lot about the improvements....

 

[wild willy]

The maff sensor effects the fuelling of a car so you can use the maff sensor in any size housing so long as the fueling is adjusted to suit and the map is happy to see higher or lower air flows.
I would only recommend descreening the stock LCR maff tube as you are not affecting the CSA of the tube or its calibration but simply removing obstructions to airflow. Many big turbo installs use an unscreened maff.
With my APR code it throws a warning light when i record over 250g/sec of air, so to combat this i sometimes run a bigger maff tube to reduce the airflow recorded by the maff sensor but i increase fueling to compensate.
When i get around to visiting Bills Dyno i'll bring a few different maff housings to see what the exact performance increases are.

Did you get my pm. I just wanted to know if theres any chance of getting the alloy joiner your using, saves having to mock up one etc, just wanted to order the exact same one as you.

 

[Feel]

How many miles you done on this tubby now, Karl? Nothing meant, just curious.

hi mate,
The hybrid route is hugely recommended and a big difference will be felt. I'm on stock rods at the moment but i'm respectful of my boost and timing settings also to minimise rod stress. When funds allow i'll fit rods for sure. Fueling wise i have stock injectors running at 4 bar but i am stressing the fuel pump a little so i've aquired 430cc's @ 3 bar to be fitted soon.
Bill badger 5 is the man to see for the hybrid kit.

Hi mate, sorry for the late reply. A company called proalloy fabricated it for me. Forge motorsport can do it also as will Bill Badger5. One day a decent mass produced version may be available for us.

Hi Phil,
I'm a weekend only sado so unbelievably still less than 10,000 miles. the engine still feels a little tight but is loosing up nicely . When you coming back to the fold mate.

 

[Dani_b19]

Thanks mate, so ill have to phone them up and describe what i need fabricating.

if you are close(ish) this weekend, dro pit round for a dyno.. (free) as I would like to reference yours to ongoing hybrids I am working on. If you are available that is.
let me know mate

I would like to say a big thank you to Bill for giving up his sunday afternoon to Dyno my car and listen to my constant chattering. It was great to meet you and see your workshop and current builds in progress as its all very impressive I'm looking forward to having my rods upgraded in the near future so i can push my setup with piece of mind and see what it can do.
We ran the car on the Dyno with a low level of boost (peak 1.4 bar tapering to approx 1.25bar) which still managed to make 300bhp. My torque was well down to my previous r/r at gotboost but for that run i was peaking at least 0.25 bar higher which would have given a higher boost figure. I tempted fate to run higher boost but my limp mode gremlins returned so stoped our play.
We'll soon see what my setup can run with a high flowmani etc and higher boost, i'm expecting 320 which is very drivable and enough power for me.
Thanks again Bill.

 

[ibizacupra]

no probs.. nice to talk with you yesterday.
your car, and mods, are right on the money...
deffo thinking 3" TIP currently on the hybrids floating by me currently.

"peak 1.4 bar tapering to approx 1.25bar" and you still made 300bhp, .Thats good going mate, I think some of the hybrids can be run between 24-26psi but not on standard rods i guess.What LB/FT did she put out?

Yep, 3 inch Tip and desceened maff should make a positive difference on the installs. i found that my set up wouldn't flow much more air without it regardless how much i cranked the boost up.
For reference this is a log before i ran at got Boost Last December:-

Maff tube is 11% bigger than stock so for comparison purposes multiply by 1.11 to compare with a stock LCR maff reading.

I think it was around 265ft/lb which sounds a little low but peak boost was lower also, so proportional. Once rods are fitted i'll crank it up to about 25psi and see what it can do. The car feels strong on the road.

Good going Willy, i always thought the hybrid was a waste and the only option after a standard K04 was a big turbo as my mate has a hybrid and i still pull away slightly (he is running a hybrid on standard manifold and downpipe). But seeing yours and what Bill has done with some K04 hybrids it has tempted me even more to go K04 hybrid next. Would i see any gains by using a 3inch tip on a standard K04? Do you have any pics of the 3inch tip and what is required to make one?

I'm sure there are gains to be had on a stock setup but i can't quantify it for you. A hybrid flows alot more than a standard k04 so will feel the choke more. If you only do the tip you will move the choke to the maff tube and then to the filter so to be effective you need to open the entire intake setup. There are some pics on this thread.

Hows the beast doing mate? We haven't heard much recently

 

[wild willy]

Hi mate,
i have some rods and high flow exhaust manifold to be fitted and a r32 throttle body to be port matched to my intake manifold. I've also bought some genesis 550's off Phil to sort my fueling if need be.
I'm looking forward to setting it up but time is a problem, but i do still enjoy this hobby.
I'm in search of a reliable 330-350 bhp.
