Engine Drivetrain 1st Gen Cooper S Most liked posts in thread: 230+whp on Stock JCW Head

My Mini makes 218 and gets me to work. Oh, and it's a fastest street legal Mini on my block. So there.

 

Oh, and one time, before band camp, I put on my Hoosiers and drove around the neighborhood. So at that time I was the fastest non-street legal Mini in the neighborhood! Yay!

 

Oh Nathan, Like i said before, ban me or let the sight have a bit more interest, a bit of arguing never hurt anyone.
you wonder why i don't post, because its more dull then watching Bea Arthur try to pick out underwear, ThumperMCS is a friend, i made a comment.
If you want ill happily continue to not further your site at all. Problem solved.

 

I think you missed the point. Its not about the product, its the annoying banter back and forth.

back on topic.

 

Colin, I've got nothing personal against you. I don't think I've ever met you and I sure as hell am not going to form an opinion based on an internet forum persona. Your logic however is flawed. A little bit of arguing is annoying to the 99.99% of those not involved in the argument. I think both the people who run the site and the majority of the membership would agree that we've been able to maintain a satisfactory level of interest while avoiding the levels of discord present on other sites. We welcome all input and all opinions, but in certain cases we always have to remind certain people of site rule #1: Don't be a jerk.

If you want to stay the course, then I believe no tears will be shed if you choose to no longer post.

 

Whoppie, I personally have three, count them, three personal track records, one at VIR, one at Road Atlanta and one at the CMS roval!!!

Can't make this stuff up.....LMAO!

 

Yup - Same here though I have the stock head (Cooper S head) and I made 230whp tuned by Jan on the same Mustang as Dave on the same day as Dave (immediately after). It's all in the tuning!

 

Great car with a nice dose of RMW goodness = a big everytime, sweet results!!!

 

Freaking awesome numbers!! And YES, over 225-230 is one fun ride!!

Just me.............................

PS: do the GP's use a JCW head??

 

Nice - my 02 Cooper S got to 230whp - stock head, with 380cc inj, but I have meth and the older RMW street cam, shorty RMW head and Jan's tuning. Fun isn't it ?

 

Very Nice Results...

 

Those are big numbers on a stock head. Congrats.

 

is that dyno before and after tune?

Do you have any baselines or impressions of where the gains in the powerband were?

cool.. it is a JCW Head. No wonder those GP's rock!!

Just a thought.. throw on a RMW Head and you will be knocking on the 260 WHP DOOR!!

Again GREAT Results Kudo's to the tuner!

Thread title updated to reflect that the head is actually a JCW Head.

 

This car already had a Baseline GP tune from RMW as there are 450cc injectors installed. This was just a fine tune. The base is pretty close, the tuner has a bit of experience with these models.

 

LOL...with an RMW big valve head, he won't be knocking on the door, he'll be running straight through it as if it wasn't even there....!!!

 

I also have a GP and was wondering what would one expect to pay for your engine mods? I am wanting to build my engine a bit but haven't really began to research what is out there.

 

Give Jan a call at 949-456-9590!! He's in Hawaii tuning right now but he'll be glad to talk to ya about what you need to get you to your goal!! Tell him I sent ya!!
