I've looked over a number of files and there is no evidence that the temps altered with my ignition Do you think we could all have constructive criticism rather than criticism

[slindborg]

It was an honest question to verify understanding before going forwards Maybe I should edit my list as its annoying to click a few times in a thread

At least were on same team lol Do you think that the ignition could be possible

[Hopegreen]

I think ignition is quite important when you talk about cylinder temps but having high values of AIT seems to me that could be some problems with laminovas, rotors or PCV. Don't know if enough "bad" ignition could heat AIT.

[CHILL Gone DUTCH]

PCV is a good point On a other thread I've been discussing that in quite some depth I've gone back to oem and do far I have no oily substance in the inlet system Can't comment on the laminovas until I take them out in winter but I'm hoping they won't be fowling up either But getting back to the ZzP stage 2 cams I had to add over 3 degrees of advance from what peter thought would be a safe starting point to get them to make any kind of power We could in bargi case have more than one variant in his high temps

[slindborg]

Are the cams a) designed for forced induction applications b.) designed to run on OEM timing setup but give the right overlap or c.) run on the mental priced vernier pulleys to give the correct overlap...

 

Head temp, radiating into the inake would only pose an issue in terms of sensor heat soak and the actual air temp may just be fine but the calibration dumps fuel in etc

[vocky]

Bargi has LSJ Blower cams, which were correctly vernier'd with some Saab cam sprockets 

 

Crap standard z22se exhaust manifold will be backing up the pressure and causing the extra heat

I'd go as far as to say the backpressure would be hurting how the engine is breathing and thats the reduction in power.

 

Where in the manifold is this TMAP mounted?

On the right hand side of this pic

 

 

Effectively the inlet to cylinder 1

[slindborg]

yeah, that'll heat soak its tits off

 

We had the A/C sensors in the Pagani going mental once it was hot... outside air temp wet from ambient to 50deg, the chamber temps were high yet the air coming out was still cool.

[NickB787]

so how can we get an accurate temperature from inside the manifold then? the position as it is is post laminova so should.. be the temp entering the cylinders ps Matt how many manifolds do you have??:-)

[CHILL Gone DUTCH]

Phenolic spacer and a hose cold air feed direct on to sensor & on to the manifold near fuel rail?

[slindborg]

Before you go nuts, you need someone who is having the temp spikes to stick a thermocouple in there to get a non radiated temperature

[The Batman]

I wish people Put this much effort into redesigning a new intake manifold

I'm running harrop on the Dutch software and I rarely see over 50 degrees on the inlet temps.

Phenolic spacer ??

[chris_uk]

yes, but heat soak still happens, it would just take longer with the spacer on.. 

 

whats wrong with tapping the hole and putting a fitting in then mounting the map sensor away from the manifold.? 

[haggi961]

Here's a power run from a really hot muggy day where it was 21 degrees outside and I had been out for a couple hour drive before doing this power run. My car was also in the layby for 10 mintues ticking over while I was setting up the laptop and getting the software to work.



My power is down slightly because my weight was set a 1065 kg.

[chris_uk]

ignore them temps...  

 

you want to log 15 mins of driving and see what really happens. 

[haggi961]

Hot day logging the other day


By looking at the box at the top my average is 48 degrees.
