Cole I’m seriously impressed with that power reading! I helped build a naturally aspirated 1275 engine back in the 70s and we were more than happy with 95 bhp! Well done buddy! 👍
Outstanding! 🎉 super happy for you having it all sorted finally, I’m sure you’ll be out driving it constantly until the poor weather arrives. Incredible figure and the power graph looks lovely and smooth. Fantastic
Hello Cole. Wonderful Mini. I have one also and have been doing some diy restauration. I wonder if your can tell me the name of the color of Bad Wolf. Thank you
@@classicminidiy it's just the cost that's holding me back, do you think it's possible to make a build similar to yours in terms of power for max 3500-4000?
I am sure it can be done around that price but you are likely not going to be able to push the engine to 200hp. Part of what makes the power possible is building out the bottom end and the clutch. Also ensuring your charge temps stay really low with an intercooler or charge cooler. Its certainly not impossible to make amazing numbers around that price point but I think overall its gonna be a tight budget at 3.5-4k. Lots of folks make 150-170 all day with a 1275 and a GT17 but the motor has to be built to handle it.
200hp? Wow, that is crazy amazing. I have a hif44 1275 with KAD performance had and cam. Do you have a video or a buying checklist of what components I are needed to go from that to SPI or MPI whichever you have, and to the turbo conversion? I am so impressed with you you ended up with after fighting your way through the supercharger and changing direction to a turbo setup. You are a true gearhead guru. 👏👏👏👏👏👏👏👏
Very impressive power! On what size (cc) engine is this? I have a 1275cc MG Midget engine with HIF 44 SU in a 1970 Morris Minor Traveller and was thinking of ways to improve it a tad; even the local busses here can keep up with me on the hills!
Nice work and nice Mini. I fuel injected my Mini engine 25 years ago by creating a throttle body out of a gutted 1-3/4" SU. It looked a bit "Heath Robinson", but it worked well. I'm sure that we just fired the 2 injectors at the same time, so I'm questioning why you are firing 1 injector at a time (unless your injectors are so large that you would get too much fuel at low rpm/power)?
Hey! Sorry for the delay in response. I went back and forth about firing both at the same time but with the size of my injectors I had to alternate them. I chose larger injectors so I wouldn't be limited at the top end and to avoid dead time issues but when I did that it meant that if I fired them in a batch config it would overfuel at lower RPM. So you have it pretty much on point for the reasoning why I went with alternating. :-) Your setup sounds like it was really cool I like the idea of it looking like a carb but actually being fuel injected.
Congrats Cole! A long way from futzing around trying to make the supercharger work eh!? Hey, I don't remember what your numbers were with the carb. How much did you gain with the FI and being able to really dial in the fueling?
Thanks Brian! Long road from the supercharger! The numbers with the carb were 173hp and similar torque. Part of what unlocked all this extra power was the much higher level of control over timing we have with the EFI. It can/could be done with a carb but its much more work and much more specialized in terms of experience needed.
Congrats sir! Well accomplished car. A controller would definitely be a nice addition especially for boost by gear… you’ll never need all that power in first or second gear.
Have you ever thought of running a 100% electric a/c unit? I've been wanting to but not sure where to purchase one. I'm in hawaii so it gets pretty hot when driving my mini around
Definitely! There are a few people/companies who have done this already. Jet Motors out in Oregon, USA and Specialist Components have both twin charged a mini.
Yeah if you go back through some of the previous videos on this build in the turbo playlist I cover it in detail but the whole gear set is upgraded to an EVO helical gearset that’s rated for the power. It has an ATB LSD. The weakest part at this point is the drop gears as they are still original but I don’t want straight cut drops.
Love Bad Wolf but would love to see you start over with a new rig, perhaps a mini pickup or van? 🤔 You could fit 2 minis side-by-side in that garage. 😂
Same thing essentially. Just run the engine. The fuel/ignition map would be a bit different but it would run it just fine. Lots of folks run naturally aspirated engines with fuel injection on the mini.
Specialist components do a 5port injection setup as well. (Same configuration as mine with their own ecu and no turbo). depending on the engine sitting under it, I’ve seen them around 85-120hp
Cole now that You’ve proven your point how about restoring the engine back to its naturally aspirated origin? I’ve seen some mini ERA vídeos and the engine sound just doesn’t feel right.
Honestly I have owned this car for over 13 years and I rebuilt the engine NA originally. It started as a 1293 high compression build. It was tons of fun but now that I have gone EFI and turbo I can never go back. The engine doesn't sound any different to me aside from the turbo specific noises which I absolutely love! And the power is absolutely addicting!
Couldn't you technically splice a second wire onto each injector to use a standard injection sequence with some tweaks? It would basically inject at the correct time, just instead of sending a signal to 4 different injectors, it would send to each of the two injectors twice.
Technically this is an alternative way to achieve what I am doing through the Haltech software. In fact what you're describing is how SX Tune that Specialist Components configure their injectors. If your ECU limits the way you can configure it in the software this is the next best way to do it.
I'm sorry Cole, I know that it sounds good but there is absolutely no way you are making that much power with that config and this fuel. If you were really making 200 bhp around 6000rpm, that means the torque would be enough to obliterate the gearbox when you even think of approaching your throttle. If you have the standard helical gearbox and drop gears, you either have destroyed the gearbox in a few dozen miles, or, more probably, you are not making near as much power as this dyno is telling you. 150 to 170 max sounds about right. And even there, you will destroy your gearbox rapidly if it has not straight cut gears and drop gears to reduce axial loads.
Cole I’m seriously impressed with that power reading! I helped build a naturally aspirated 1275 engine back in the 70s and we were more than happy with 95 bhp! Well done buddy! 👍
95hp is still impressive today for a road friendly engine
Thank you!! I totally agree with The GTE Channel, 95hp is an awesome result, and I bet it was a blast to drive.
That's an impressive power curve. Be good to see out and about driving. Very nice 👍🏻
Huge result! Amazing.
Yes it was! Thank you!!
Awesome. Congrats man.
Thank you!
Outstanding! 🎉 super happy for you having it all sorted finally, I’m sure you’ll be out driving it constantly until the poor weather arrives. Incredible figure and the power graph looks lovely and smooth. Fantastic
Thank you!! Whats poor weather? You mean "cold air turbo weather"? :-D
Mind blowing! 🤯
OMG 😳 200hp in a mini is crazy. Fair play one is impressed 👍
I know I am blown away! Thank you :-)
Insert Emperor Palpatine “unlimited power!” meme. Amazing work Cole!
muhahahahaha
Hello Cole. Wonderful Mini. I have one also and have been doing some diy restauration. I wonder if your can tell me the name of the color of Bad Wolf. Thank you
Great episode Cole and really good power, great work 👏 👍
Glad you enjoyed it! Thanks so much. :-)
Damn that are some crazy numbers! Got me having doubts about building my 1275, might want to go efi turbo now😬
Its a deep rabbit hole but its a very fun one! I am totally hooked on EFI now, I don't think I can go back...

Wow 👌
So crazy! Creat job man!

Cole, what diff ratio are you running? 3.44? 3.1?
All that power must be down to the cylinder head ! :0
No doubt a huge part of it. Can't get big numbers without getting the boost into the cylinders. Thanks again for making such a well done head!
Great power result there Cole 👍🏻😎
Thank you!!

Thank you! Absolutely I am trying to think about how I could add a gear sensor for the car but I havent quite thought of how just yet.
@@classicminidiy You still have a mechanical speedometer? If it’s the case, you could get the VSS pulse on a hub like modern car abs sensors 🤷♂️
Have you ever thought of running a 100% electric a/c unit? I've been wanting to but not sure where to purchase one. I'm in hawaii so it gets pretty hot when driving my mini around
Hi. do you keep the original connecting rods on this engine? good result
Yes the A+ original rods are actually very strong. No need to change them unless you are trying to lighten the rotating assembly up.
yes, I was seeing that you only modified the original connecting rod bolts for arp bolts, right? greetings from Spain, you do a great job
Do you think it would be possible to twin charge a mini, if you don’t know this is when you turbo and supercharge
Definitely! There are a few people/companies who have done this already. Jet Motors out in Oregon, USA and Specialist Components have both twin charged a mini.
Oh my other question. You mentioned other base map ideas. Considering adding one for the Emerald K6?
Absolutely. If you can send me an empty map to classicminidiy@gmail.com I will port it over this weekend. :-)
@@classicminidiy Sent.
Did you do anything to strengthen the gearbox? That's a lot of HP and torque on a gearbox that was designed for 65ish HP and 70ish FP torque.
Yeah if you go back through some of the previous videos on this build in the turbo playlist I cover it in detail but the whole gear set is upgraded to an EVO helical gearset that’s rated for the power. It has an ATB LSD. The weakest part at this point is the drop gears as they are still original but I don’t want straight cut drops.
@@classicminidiy gotcha. I will look back for that one
Love Bad Wolf but would love to see you start over with a new rig, perhaps a mini pickup or van? 🤔 You could fit 2 minis side-by-side in that garage. 😂
I would love that. Just need to get this weird thing called money to buy another one. This money stuff always gets in the way of everything!
what would these electronics do without the turbo ?
Same thing essentially. Just run the engine. The fuel/ignition map would be a bit different but it would run it just fine. Lots of folks run naturally aspirated engines with fuel injection on the mini.
@@classicminidiy i notice MED just has an ignition ecu , KAD injects the 16 v . yours is the first i've seen with both . q
wonder what hp minus turbo
Specialist components do a 5port injection setup as well. (Same configuration as mine with their own ecu and no turbo). depending on the engine sitting under it, I’ve seen them around 85-120hp

Technically you can, but you can back feed the ecu, which isn't great. The D400 does it, but haltech allows you to do it in the software.
👏
I'm here for turbo noises
Lucky for you there are lots of those. 🙂
I am what is commonly known in some circles as second.
Everyone’s first in my book.
At CMDIY we’re all winners
@@classicminidiy Nice
You should track it!
I agree! I have done auto-x on and off over the years but nothing super formal.
Driving video?? I would love to see
It ripping down the road!
Good idea! Its almost fall so its the perfect time to go rip in the mountains. :-)

Cole and his self-deluding power figures, always good for a laugh.
Sorry the dyno gave results you don’t like.
