MGBGT performance engine build… it finally hits the street

[@aggiebq86]

I’m going to have to go back and watch your videos on the engine build. This is the type of performance I want in my 66 MGB.

That was a really nice ride along. That sounds good.

[@erikdressler5129]

She does sound sweet

[@984francis]

Interesting how even a modified B still sounds like stock, meaning for me, the best sounding 4 cylinder ever.

[@americanpatriot2422]

Great video

[@bradthurlow5503]

Looking foreward to your timing efforts. With a similar spec engine I found I couldn’t get idle timing AND max advance at the same time. Curve was wrong for my engine. Rather than guess with recurving my distributor, I went to a fully programmable 123 which solved that problem for me.

Saw your cars at the show today

Sound healthy 👍👍

Glad you got her running ----- sounds pretty good ----- looks quite strong ----- Are you using the HS-4's or larger ones? ----- Like "philipschmid" in your comments asked -- I too would like to know more on how you made your car sound so good ---- Now that you got her back together and running ----- to make some suspension adjustments ---- bet you can hardly wait to get it on the track ----- it's been a while for you ----- Thank You for the video ----- probably all smiles now ---- Hope you have a Good week --- Rodney

Very nice. Have you fitted a lightweight flywheel or kept standard flywheel and clutch.

[@mgbgtguy]

The flywheel has been lightened to under 16 lbs.

How did the suspension feel? Car sounds great and pulls well I think

[@mgbgtguy]

I haven't done any adjustments yet, so at this point the only real difference is the slightly stiffer springs than stock. Remember though, this suspension set up doesn't actually change the geometry, it really just gives easier ride height adjustment, and adjustable shock stiffness.

[@philipschmid9352]

What type of exhaust do you have fitted?

[@mgbgtguy]

The exhaust was hand fabricated by me from the header to the tailpipe, including the muffler

[@philipschmid9352]

​@@mgbgtguyThanks for the reply! That's a shame... Is there anything that sounds similar?

[@mgbgtguy]

I don’t think so. Part of the reason mine sounds the way it does is that I do not have a rear muffler, the only one I have is in the middle of the system (under the driver seat), that muffler position will change the tone and most available aftermarket systems will give you a rear muffler and not a center one. I basically built a loose copy of a Flowmaster Delta flow that would fit in the space available.

the new c8 corvette has a software enforced rev limit of 4000 rpm for the first 500 miles. probably a good starting point for any OHV engine. i recently viewed the tragic consequences involving a german youtuber that is/was a BMW nut. he spent countless hours rebuilding a performance oriented BMW engine only to have it blow up on it's maiden voyage outside the shop. on that initial drive video, i watched as he roared away down the road, right out of the garage, and on to the first autobahn he could find, going on and on about how fast the car was (in excess of 100mph). then blasting through the countryside, upshifting and downshifting at redline all the while....until the engine suddenly stopped. after having the car towed home, his next video was spent disassembly the engine and trying to blame the parts and the machine shop for the failure, but i knew what, most likely, was the cause....

There are lots of thoughts regarding breaking in the motor. Anything from being extremely easy on it, and never rev it to full throttle runs and break it in the way you’re gonna drive it. Most of the time if there’s a failure it’s because it wasn’t built right to begin with. Any engine builder who dyno’s their engines first do not in any way baby them on the dyno, in fact, after the cam break-in and some tuning, It’s full throttle runs right to redline. If your theory is true, then how do those motors not blow up right on the dyno? By the way, I do have a pretty conservative rev limiter set up on the car right now (5200 rpm’s)
