Pre Turbo Injection Recorded Temps
I borrowed a dataharvest from work this weekend, ive recorded over a hours worth of data.
I used four thermocouples, one before the WI point, one before the IC, one after the IC and one at the manifold. I started with a 0.4 jet and worked up to a 0.9 jet. I noted the time on a stop watch after each jet change and drove up to the top of a long steep hill, which allowed me to hold boost for a considerable amount of time. Finally i did the last run with WI off. Should be able to post the results on monday :smile: I want to find out the optimum jet size for cooling the inlet charge. Ive noted that the turbo was a lot cooler (quieter, not hissing) when i pulled over to ghange jets from 0.6 upwards, also the post IC temps were higher than the post turbo temps at these times. ( So i kept the engine running while changing jets from that point onwards). |
Pity the weather not as hot as one like but at least it wil be consistant.
I look forward to your results. Look out for nails :wink: |
Ive testing been driving with the spare on, not ideal really, but wouldnt effect inlet temps :smile:

Richard,
im not sure how to post the excel file ????????? |

Send it to "john@max-boost.co.uk" |
Im going to repeat the exercise again this weekend, the temperature was being sampled every 15 seconds, my work colleague will set up the equipment up to sample once every second for this weekend.
I will still post the first set of results as soon as i can. JohnA: I'll email you this coming weekends results, which should be more comprehensive. |
No matter it's a table or graphic, you may cut & paste onto a PowerPoint template. By that, you can "save as" a .jpg file, that would be much more convenient on this forum.

Evapouration is continuing down the 20" pipe from the IC to the throttle. Thats after the water travelled 10" to and through the turbo, and 18" to and through the IC. |
WOW, that is one 1.5 hours of full boost :twisted: I think the magenta peaks are the on-boost period?
These datas are so good, thumbs up for posting the chart. Please remind me where all the jets are or it is only one in fornt of the turbo? Awesome work!!! :D Richard |
