Air intake test AP1 S2000

[e240]

.. obviously if it waas built properly to start would off been fine all way thru.. i dont know who perry is.. but ive seen a motor that youve built that the block F&#$ing blown a HOLE out the side and piston.. rod.. u name it bloody came out of.. so shit i dont think thats a good way to run a business.. your making a bad name for company.. look around everyone saying PERRYS MOTOR this that.. and another thing...

Hey, get your facts right...Here's an independent opinion from another reputed Tuner/Engine builder on that motor.

jdmtyper

i dont know who build the engine or tuned the engine BUT...

alot of times blowing an engine is not so much the engine building but also sometimes the tuner could be at fault ...
for a conrod to fly thru the block... according to my experience, it must have too much advance timing in the tune. so my advice is not judgemental im not accusing or helping anyone. as i dont know who are involved...
okay here goes..
point
0)if engine is built badly(assembly) it will blow up in the first 20 minutes or during run in.(assuming that all products will not fail)

this is what mostly must have happened on the engine.
1) on the up stroke; the cylinder is firing, causing a downward force on a upward piston. thrus snapping the conrod(which is forged aftermarket assuming that product should not fail).(if piston have melted edges it confirms it, will explain but take 2 pages) but biggest give away is the twist in the forged conrod.

OR

2) advance timing sends a downward force on the bearing that crushes the main bearing causing an imbalance crank. throwing conrod out of the block. i think tis is unlikely the main cause; as this is a long process and you will hear the bearing knock and stopped flogging your car before the conrod flys out.

the way the conrod failed was from compression Twist... up action + down action at the same time. clearances was not a problem.
you would probably see scratch marks on the side of your cylinder wall (i dont know if you did, i definately havent im in a different state.. haha) and thought it was a clearance problem. but it's not. let me explain
as your piston is going up and advance timing is firing; the sides of the pistons get pushed down(as it does not have a conrod supporting it) and creates more surface area as the piston is getting streched.eg. from this /---\ to this \---/.. this extra surface area touches your cylinder walls and the friction melts and scratches the sideof the cylinder wall.

but ultimate failure was from conrod twisitng, snapping and punching the side of the block... piston mush have shattered at gundgon pin area, as most stress will be at that part. if it was clearance problem, it would have sheared/teared off instead of compressed twist failure as it would be jammed on the downstroke.

i think im right...


i have been selling parts for years and i know for a fact that the tuner will blame the engine builder, and vice versa when an engine blows up... and on the opposite they will claim the build/tune the engine when it does a good time.
im not saying it's the tuners fault. or engine builders fault. but have a open mind, and an analytical mind, look at what went wrong... and you'll be able to know what happen.

sometimes it's not the engine builders fault, it could be the tuners fault or vise versa. (unless he build and tuned it.. haha) so i think the moderators were right in that sense because you will really not know the truth until you study it... so good luck with your second engine...


P.S.my 2 cents worth i have never seen a forged conrod break like that from
bad assembly... and i got a Bach degree in engineering and i studied "finite element" in my last year. so i know a little bit of how things go boom.. im not tryingto be smart .. imjust bored they called of the drags tonight because it rained

standard engine(spoon is pretty standard..) do last longer than worked engine. as worked engine are getting Horse squeezed the living daylights out of them..(unnatural >>>> thats why you ned to forgedd the parts)...

but even a worked engine or a engine made with diamonds cannot withstand bad tuning.. or bad assembly... or bad driving for that matter..
not saying you are a bad driver.. or have a bad tuner or bad garage

engine builders and engine tuners go thru alot of pressure...
it hard for a tuner to squeeze horses safely, or engine builder to be careful of the thousand of bolts and washers in an engine.

am i right?? on my assumption based on the 3 blurred photos?? let me know. whati hve missed out and we can all learn from this experience together. but if im right 95% of the fault lies in the tuning...
i still dont know the people involved.. it dosent matter... thats not the point. the point is im sure the tuner deep inside knows he wont let that happen again.. )

btw the engine is not owe by you right?? it's ur friends right??
im getting confused.. just trying to help..

In fact, you should find out who tuned and maintained this engine for a good many months before it went. Also, it was tracked and trashed many times (ovvvveeeerrrrvvvvvveeeeddd) and by a number of different people.

Oh, did I mention that the engine only went after over a year? don't forget, this was a track engine...and made many many return journey's from Orange.

If I were you, I'd be more concerned about my own engine and who's touching it.

man talking about perry motor went from shit to worse....

No, Perry's car went pretty well when I followed it...A pity I just never got the chance to drive it, otherwise...

hey E240 look.. im just saying what ive seen and what ive heard.. this thread was supposeto be for the boys outcome on their intake kits.. and hey i can you and everyone out there that im 150% satisfied with the kit.. i support them in what they are selling and would recommend it anytime..

its cheap and very effective..!!! and im happy with who touch my car.. theyre are very qualified mechanics.. ive seen their work and cars that theyve built and have built a strong reputation for themselves and their workshop..

but anyways... intake kit-------> cheap very effective!!!! so if you wana be stubborn then dont worry.. but if you interested then again as i said i would recommend it anytime...

[e240]

We had a chance to take it for a session around wakefield in Perry Old ek with the toda built motor, hmmm how can i compare.... worst then a b16a motor?

Yeah, but given all the above posts, your opinion unfortunately is biaised.

[e240]

Aznsiko, as long as you're happy, thats fine - why bother about people's opinions? Everyone is entitled to their call, they don't have to accept the findings. If one had to reply to every post they don't like on an open forum, it had better be their full time job and I hope it pays well.

I have great respect for all the tuners and builders, everyone's build great engines, you don't hear me putting down other tuners do you? but what I'm against is a one sided story, especially when facts are deliberately being hidden for personal gain.

Unfortunately, painful & expensive lessons has led me to one builder/tuner who can be brutally honest, and some people don't like that.

sums up this thread. Hypocritical of the thread starter , and shame on everyone here taking a punt at everyone else.
