Revolution Mini Works cylinder head/header 246whp!

[Revolution Mini Works]

It's becoming old hat going past the 240+whp .... figure your favorite correction factor to make your BHP numbers.... one thing we know at RMW..... cars fade quickly in the rear view mirrors

Many "talk" about these numbers..... How many actually prove them and then on the track?
this car had 66,000 miles on the clock
15% pulley, CAI, aftermarket air to air intercooler, RMW cylinder head and exhaust.....

we have one stage of cylinder head................FAST.... no need for mulitple stages, they cost the same to make and anyone telling you different is pulling a fast one on you
what you get with each one of our heads is brand new bronze guides custom made for our heads. Why? because the stock ones are cast junk and will go south on you in heavy duty situations.... We carry only the BEST valvetrain... no skimping here...
Black Nitrided stainless steel valves (inconel available) titanium retainers, dual valvesprings, special locks and keepers... don't be fooled into inferior parts as many of the triple groove type valves drop valves on the track. Ask you manufacture what they use and have them prove to you what is on the head.

How much is your cylinder head? And where can they be bought from?

$1995 direct and can be installed at 1320 autos... we will be featuring CUSTOM tuning live on the dyno

those cars also have my header which is custom tuned to the cylinder head

Does that have a hi flow cat or decat. Also would that manifold be able to be connected to a JCW catback or does the cat back need to be changed? With this cylinder head does it have bigger inlet/exhaust vales? (would it fall into a stage 4 category). How much is the manifold and what sort of noise increase over stock?any sound clips? Is a remap required when cylinder head is changed?

Would this go well with my other mods?

15% pulley
JCW CAI
JCW catback
JCW remap
Bigger I/C
380cc injectors
Cooler plugs

Also what is 246whp in bhp(fly)

Regards

James we've seen anywhere betwwen 28 - 40 bhp drivetrain loss

We have some customers who have already placed there orders and we will report our findings on here as soon as we know the results.

We will be going back to Surrey Rolling Road to see what we get with our customers cars as Roland recognise this rolling road as being accurate.

Some of our customers will be ragging them up the strip as well to prove what horsepower they have as well, this is the best way to show the whole world what horsepower you're making.

Some of these customers will also be doing various trackdays as well and I'm sure will report there findings on here.

It looks like its going to be an exciting 2008 for Mini horsepower in the UK on any street or at any track.

OHHHHHH YESSSSS!!!!

quallity results Jan you'll be hearing from me soon me old china!

I’m not a detractor; RMW products deserve attention, but I would like the readership to be aware of some things when evaluating the numbers. There is nothing wrong with quoting peak numbers, however often times they are quoted (by vendors and enthusiastic users) without mentioning redline has been moved and peak numbers were obtained at higher rpm than base numbers. When you see a baseline peak number at higher than stock’s redline, the base number was obtained with a modified ECU. When looking at deltas at the drag strip, a torque peak at higher rpm (and/or manipulated redline) provides a later shift point which can eliminate the need for one shifting event depending on the transmission model, eliminating a shift alone can improve times; more torque later in the rpm band is a product of headwork and can be in some degree a function of the ECU program, higher redline is a function of program manipulation. I’m a big proponent of headwork but keep in mind whether the ECU has been optimized for either or both heads being evaluated and whether improvements have also been made on the exhaust side. There are other things to look for also, just dig a little deeper than peak numbers for comparison.

Thanks for this

One thing I always look at is the redline and where it is compared to stock - I then take the stock red line and look at the power etc at that point. I then look at the area under the curve up to stock red line.

Apples need to be compared with Apples

And when you drop the clutch at 7400 on slicks the rpm drops down to 1400rpm so to gain a good 60ft you need loads of torque between that point and whatever you are shifting at.

I'm hoping we can find loads more torquein the oming months as I would still like to be the first in the 12s with an M45

We've been concertrating more on the area under thats why we believe our cam is better than the shrick, we'll do some back to back test soon with the ecu's fully tuned to suit to make it fair

[Revolution Mini Works]

people always make excuses when they get whipped on the track.... it's a way of life

I don't care if you rev your car to 10k... if the head won't flow it... it's a moot point

like I said...overlay those torque curves against yours.... you will see why we pull away on the track

Jan tuned my '02 MCS today too. The results are excellent:

best baseline pull: 182wHP @ 6900 RPM and 162wLb-Ft @ 4500 RPM
Post Jan tuning: 198wHP @ 7100 RPM and 173wLb-Ft @ 4450 RPM

My car has a 15% s/c pulley, 0% crank pulley, ALTA CAI, OBX header, and my own 2.5" stainless "Cooper style" exhaust.

AFR's ramping from 13:1 at the beginning of the run to about 4k RPM and then 11.0:1 to 11.5:1 through redline, which is excellent for our 10% ethanol fuel.

Oh, I didn't do a "sniffer free" run like TheWrks did; his best "sniffed" run was 202wHP! Cheater, ! {I'm just making myself feel better that a JCW beat my car!}

Cheers,
Ryan

I nicked this off NAM, I would defintley be happy with an extra 16whp for a 200rpm increase

Ryan is one cool dude who you be hard pushed to pull the wool over his eyes, he built his own turbo only R53 2-3 yrs ago

Here is another guy in the club that HAD MTH on his car
then I tuned it Here is HIS commentary....

Sorry I'm posting my results so late. I had my '03 MCS tuned by Jan last Thursday. I have been wanting to do this since Sept of '06, that's when I initially contacted Jan. But things didn't work out and we never hooked up. Lately I was seeing all of the posts on what Jan has been doing to everyone's cars. So it peaked my interest again and I bit the bullet and scheduled a time for Jan to tune the car. Current mods are Alta CAI, 15% pulley, Magnaflow catback and the first MTH mapping. Jan noticed that I had some type of remapping done and told me that it had way too much advanced timing in it, like 3 or 4 degrees. The baseline dyno pull came up with 179.8 HP and 163.1 foot lbs. of torque. After Jan did his magic and the final numbers ended up with 203.4 HP and 181.3 foot lbs. of torque! Wow! What a totally different beast I have my hands on now. BTW I'll be in the market for some new front tires now since I've burnt off all of the remaining tread left on them. Here's the dyno chart to shows the difference:

The last two posts are examples of why I suggested looking deeper at the numbers. Both posts were about the tune, neither examples had the thread topic “head and header” listed as a contributing factor. The examples would be good for baselines if a RMW head and header parts were added later; then it would be comparison of two optimized configurations with the tune variable playing a lesser role in the delta, but a role none the less.

Keith,
I know you are a sharp guy... this whole point is really about the head/header
you have numerous posts around the web showing my tunes... with ALL types of configurations...
NONE of them hold the torque like my head/header combination.... there is a reason for it... the design

the tune brings out the best of each part, whether its my parts or someone elses....
