carbonboy Posted April 17, 2015 Author Report Share Posted April 17, 2015 It was the ladies screaming as he drove past. Squeals of amazement & screams of horror are quite different I'm afraid, most likely the latter. What's up with the squeal noise? It sounds like a belt or maybe a bearing? It does sound very belt-like, I've run the engine sans drivebelt & the noise is still present. Obviously haven't run it sans timing-belt, but I don't think that's the cause. I've tried using a stethoscope but I'll be buggered if I can pinpoint the exact source. I believe that it's somehow vacuum related, as the noise only occurs when off the throttle, the moment I touch the throttle it goes away. Using the MSD software on the laptop, I've found that it will only occur when manifold vacuum is at 8.50psi or less. Which is making me think it's either a pinhole leak in my intake manifold or the carbs themselves. Quote Link to comment Share on other sites More sharing options...
Taz_Rx Posted April 18, 2015 Report Share Posted April 18, 2015 What sort of fuel pressure reg are you running? Quote Link to comment Share on other sites More sharing options...
LittleRedSpirit Posted April 18, 2015 Report Share Posted April 18, 2015 I think the squealing is clutch related, either the pilot or throw out bearing is on the way out. Sometimes you get a bad one, or they get damaged during installation. A mates Hilux was doing the same thing as it had a new clutch under statutory warranty and they just chucked a clutch kit in and didn't replace the bearings.

carbonboy Posted April 18, 2015 Author Report Share Posted April 18, 2015 What sort of fuel pressure reg are you running? An Aeroflow branded low-pressure adjustable regulator, with a return line plumbed into the outlet side. I think the squealing is clutch related, either the pilot or throw out bearing is on the way out. Sometimes you get a bad one, or they get damaged during installation. A mates Hilux was doing the same thing as it had a new clutch under statutory warranty and they just chucked a clutch kit in and didn't replace the bearings. It does have that sound to it, but would the noise change depending on whether the clutch is engaged or not? It doesn't change when I press the clutch pedal, so I kind of dismissed it. nOOb error?

Taz_Rx Posted April 18, 2015 Report Share Posted April 18, 2015 Ah ok, the aeroflow should be pretty good then. Malpassi's can get a bit noisy when under vacuum at times, mine sometimes sounds very similar to your noise. Maybe just try removing the vac line to the ref and see if it makes any difference.

carbonboy Posted April 18, 2015 Author Report Share Posted April 18, 2015 (edited) There is no vacuum line to remove. :) Edited April 18, 2015 by carbonboy Quote Link to comment Share on other sites More sharing options...

rian Posted May 12, 2015 Report Share Posted May 12, 2015 Maybe you have a mosquito stuck in your air filter and the low pressure gives him a headache? Quote Link to comment Share on other sites More sharing options...
carbonboy Posted May 16, 2015 Author Report Share Posted May 16, 2015 I am feeling the need to kill this mosquito, beginning to give me a headache. Distracted myself from it by installing the coilovers. Liking my existing ride height for its practicality, I only removed 10mm of height from the front & 5mm from the rear. Had a small drama at first, due to wheel offset/185 tyres, the inside edge of the rear tyre rubbed on the spring perch. Tried fitting a 175 tyre, this gave me clearance but I want to run the widest tyre possible & be the same at all four corners. Reduced the rear camber from -2.3° to -1.4° & this solved the problem. From start to finish the alignment took me about an hour & a half to get right, but when you have an alignment machine at your disposal & you're not paying for labour... :) Running -2.3° camber with 0.5mm of toe-in on the front & 0.0mm of toe on the rear. Test drove with the suspension on the softest setting, felt just like the KYB's with the KS lows. Went 4 clicks firmer & suffice to say that's firm enough for my local roads. The difference in handling is mind-blowingly awesome, the front has so much more grip & there is very little roll through corners & lunging under brakes. 10/10, would install again.

altezzaclub Posted May 16, 2015 Report Share Posted May 16, 2015 & be the same at all four corners. Don't get too fixed with that idea, there's a lot of tuning that can be done with different tyres front & rear.... My first modern car was a 1964 Mini Cooper with front tyres much wider than the rears. That had adjustable LCAs and no understeer now I think about it.

carbonboy Posted May 17, 2015 Author Report Share Posted May 17, 2015 Agreed, it's not an end of the world thing, just personal preference. Managing tyre wear with directional wheels & asymmetrical tyres is fun enough as is. ;) Quote Link to comment Share on other sites More sharing options...
carbonboy Posted June 9, 2015 Author Report Share Posted June 9, 2015 I entered BT in the trackday at TCCAV's Winterfest/40th Anniversary at Sandown yesterday. Not just for racecars, participants in the Show n Shine were given the opportunity to drive around the track under pace car conditions. Courtesy of a mate of mine, managed some in car footage. Playing overtakies with an AE82, completely missing the braking point at turn 1, an off-track excursion & a smokeshow to finish...This one lap has it all! My day didn't go so well, started blowing smoke in the first session & nothing I did during the day was able to rectify the issue. Managed to drive her home & to work this morning (to use hoists for inpection), she wasn't real happy though. She expressed her displeasure this afternoon by pressurising the radiator overflow bottle with oil. RIP Engine Number Two, you were fun while you lasted. I came, I tried, I failed. Twice. I have zero desire for a three-peat. The replacement is going to be a standard EFI 4A-GE 16v bigport. Quote Link to comment Share on other sites More sharing options...
