- In this video I'll be showing you the 1.5 high lift rocker kit that I'm going to use on my 1275 engine. I've filmed the assembly process for you to watch.
Also I'll show the new Maniflow Stage 2 RCM exhaust with central rear twin silencer. I'm not going to film the whole installation, but it will give you an ideo of what the parts look like.
Additional video's will be made on how the Stage 2 and RCM parts work, and how they potentially could benefit the engine. In a later video you'll get to hear this masterpiece, and let me tell you... it does sound great!

so if I swear before I order it do I need to do that when I install it :-) ?
Its no exact science ofcourse but I think the part needs to hear you 😆
Please report back on how successful it was 👍
Thanks for watching
I have that exact rocker kit on my 1275 supercharged Buckeye Sprite. I installed the rocker kit at the same time as the installation of Long center branch headers so I can’t say how much additional power I got from the rockers alone. But I will say that the combination of headers and the rockersgave me a substantial increase in power, particularly in the mid range.
The best way I can explain is that my engine feels much eager to rev. The mid and top range definitely feels stronger. I also have a modified cilinderhead.
A supercharger is also on my wishlist for the future, what's your experience?
In the aircraft business we used to call that "swearing it into place", lol
It's a great tactic, I wish I knew it earlier 😆
Very cool!!
Nice video Dennis! Nice explaining from your work
It was also a test to try filming with a new camera. Let's see if we can make more quality content on the Mini and Puma in the future!
Very nicely done ! Thanks for the time spent on sharing. Would like to hear how it sounds
Thanks, I still want to make a video with my friend who had an RC40 to compares the sound. I love the sound, I do think the sound inside the car is louder than a RC40 but it sounds glorious!
That would be great to hear both
@@nalinfernando8093 still haven't found the time to record the sound. It does sound really throaty! Little natural pops and bangs when pushing hard. Will ask my friend when we can meet to record the sound
I have a new video recorded on the inside of the car. I'm planning some drive by's as well. I side you can hear the rumble of the exhaust. I wonder how it sounds from the outside
Great video but where is the sound demonstration ?
I can't find it.
I do not have any sound from the outside at this point. My son volunteered to help with filming so I hope to share that somewhere next week. I do have a video from inside the car, but don't think it does justice to how it actually sounds. I'll notify you when I have some good sound material.
So what’s your feedback since installed it on your car?
Hi, its a real good sounding exhaust. It sounds really raw when revving the engine. Its definitely not subtle. It has a nice rumble when going of the throttle, but still need to modify the needle in the carb a bit more so that might disappear, or get even better 😆
@@GTE_Channelandò what about the performance? Is the rockers a good stuff to make a mini faster? I have a 1991 rover cooper 1275 hif 44, what’s your car?
Hi I also have a 90s Cooper. Does your engine rev up to 6000-6500 rpm? If so, you have a Metro camshaft (about 266 degrees) wich was fitted as standard.
I feel there is a lot of misinformatio about high lift rockers, but for a Metro camshaft the high lift rockers will give you no noticeable loss of power at low revs, but will give a few more horsepower in the high revs. So the powerband shifts towards the top. It's up to you if that is what you like. I like it. Don't expect a great transformation in power.
After a modification like this you probably need to get your needle re profiled. If you are going this route I would advice to take off the airfilter snorkle and drill holes in the airbox (lots of info online) this modification can potentially give you up to 5hp.
If you have the chance to take off your carb there is also a few horsepower in changing the butterfly in the carb for a flat one. The Coopers have a sort of bypass valve on that butterfly for emissions reason. It'd terrible for performance.
Best of luck, if you need any info zi can always post a small video for you explaining the details.
Oh.... a friend of mine just installed 1.5 rockers on a 266 camshaft and he says it really woke up the top end.
@@GTE_Channel Mine is a 1991 Rover, here in Italy it was only sold in 1991 with the hif44, after which the cooper spi and mpi arrived. I don't know which cams it has, in the booklet it states 61hp. Unfortunately my Mini struggles to exceed 5000-5500 rpm, the spark plugs are always very black even if I try to adjust the mixture screw. I think I need to check the ignition timing.
@EjuEj I understand. Let me give you a real good piece of advice, this is really important to understand:
The mixture screw should only be used to set the correct mixture on idle. If the cars does not run properly somewhere else in the rev range due to fueling the only way to solve this is to re-profile your needle. There is no there way. Trying to adjust this screw to make your car run better can potentially destroy your engine.
Reprofile of the needle needs to be done on a dyno by someone who understands HIFF carburetors, or if you install a Wideband gauge I your exhaust you could do it yourself.
Your engine not wanting to rev higher can have lots of reasons, some not even engine related. You might have a Metra camshaft, but you also might have the tamer version wich is all about torque (acceleration) , wich isn't that bad to be honest.
Maybe we can get in touch via WhatsApp, maybe that's easier to communicate so I can help, if you want that offcourse.
