I personally think so 😂 What other questions would you like to ask someone like Jeremy from JE? Let us know below - Taz 👨🏻

[@WyFoster]

Andre is so good at interviewing he practically answers the question with his question lol

[@blindabinda1234]

I'd be sweating knowing Andre is going to be interviewing me... I'd have to bring a notebook with lots of bullet points..lol

[@Biteme1010]

Im pretty sure Andre already knows the answer to all the questions he's asking. He's just waiting politely for his guest to answer.

[@josephpillado9204]

If only Andre could interview my eBay part supplier before I purchase

[@Runmeerkat]

LOL

[@MafiaboysWorld]

Andre asking the hard questions to ensure that he's getting the perfect pistons for DOCILE. 😉👍 What a champion! 🤘 #Day151OfContinuousPeerPressureOnAndre

[@hpa101]

ikr, sneaky wee sidetrack into drag racing there. His subconscious knows he wants to...😂- Taz #bringbackdocile

[@MafiaboysWorld]

@@hpa101 I know right Taz, yet he still persists trying to prove me wrong that he's getting more distance per dollar out of the 86. 😛👍 Never gonna happen Andre, you could run DOCILE on Nitromethane and still be cheaper per mile than the 86. 😂🤣

[@LilFoxAK]

brooo this was a fire talk!!! love this interviews so much!

[@hpa101]

Glad you enjoyed it mate! Always a ton to learn from the JE team. Keep an eye out for our next JE piston giveaway in the future too 😎 _ Taz.

[@LilFoxAK]

High Performance Academy will be doing so! your channel is literally an encyclopedia for tuners. some of the guidelines for tuning and building. thank you for sharing so much valueable and critical info !

[@grecoconduris6716]

Wow that takes me back to metallurgy classes. The teacher smoked a pipe and he had a tooth missing in the bottom which he hung the end of the pipe from.

[@hpa101]

Some people just know how to make the best of a bad situation eh haha Although I wonder if the tooth was missing because of the pipe-smoking 😅 Glad you enjoyed this one Greco! Cheers for the comment - Taz.

[@gordowg1wg145]

Good, informative interview. Could you ask some of these piston manufacturers what their views are on single compression ring pistons Vs the more common 2 ring pistons? While there's the option of running a higher pin height and longer rods, and there is less ring drag which potentially give more torque/power - is blowby and oil control significantly compromised? Oh, could you also ask the piston manufacturers representatives - well, the ones like this gentleman that knows their stuff - why more performance/race gudgeon/piston/wrist pins aren't tapered? They're primarily loaded in bending, where the piston is loading the connecting rod, and in shear between the sides of the connecting rod and the piston - both loads which need the most strength in the pin. But there in no real bending or shear loading towards the outer ends of the pin and so the required strength, and mass, requirement is dramatically reduced. Worse, it adds to the inertial loading on the most heavily loaded centre. The crush loading, though, will be roughly the same in the piston bore, so there will need to be material to resist that force. Not sure if I worded that well, I hope you got the gist.

Hope they make a 2.2 stroker for the sr20

[@deathbo971]

What about heat reflection from the ceramic coating? Into the cylinder head and valves?

[@weliftnation2418]

Can this coating hurt sleevs, or CSS?

[@VR6NAVYVW]

The combover Mohawk got me dying lololol

[@marklowe7431]

Make the measurement window a dad bigger and use a standard mike

[@valentinolim7144]

Did anyone noticed David Freiburger on the tv?

[@hpa101]

I missed that, thought I saw Mike Kojima though. After having a quick flick back through I have no idea where though haha - Taz.

[@jareknowak8712]

Yep, Freiburger fan here! :)

[@joshuamoore24_7]

You should have showed the coated piston after 50,000-100,000 miles.

[@hpa101]

Sir, you want a stock OEM engine if you're gunning for 100,000 miles of trouble free motoring with nothing but air filters and oil, plus possibly a cambelt by then I guess if applicable. That is what they are designed for 😉 - Taz.

[@bentennyson6009]

What's a puston ?

[@hpa101]

It's possibly the sign of a poor education system. Where did I typo that? 😅 - Taz.

[@Pork-Chopper]

Better to be Pistoff than Piston!

[@DhavalDedhia]

Doing my exam in 8mins but #gangduties

[@hpa101]

Best of luck with your exam Dhaval! - Taz.

[@gordowg1wg145]

@@hpa101 Maybe he'll give an update when he comes out?

[@DhavalDedhia]

Thanks Taz!

[@FOXCRF450RIDER]

It's a shame you basically had to do the interview for him. You were the interviewer and interviewee

[@hpa101]

Nah Jeremy was all good. It's one thing to answer a question, it's another to do it on camera after spending an entire week setting up and SEMA and talking non-stop 😎 - Taz.

[@FOXCRF450RIDER]

@@hpa101 I've done the SEMA thing with big companies so I know how it is. He doesn't have to try and sell it but he should from a technical standpoint in this type of video. I just felt you had to prod him. It's all good, just my opinion. Great video

[@hpa101]

I hear ya, we'll see if Jeremy can redeem himself in your eyes next time we have a chat to him. Usually once the first one is under the belt and people get to know Andre they get easier and easier. Glad you enjoyed it either way :D Are you heading to SEMA this year? We're going to have to sit things out I think - Taz.

[@FOXCRF450RIDER]

@@hpa101 Yeah tell him I want the TECH, lol. I thought SEMA was already cancelled this year but I never know, working on a race team, it usually depends on if our truck(s) will be on display.
