Any FI gurus out there.
If I build a larger Type IV would it be possible to adapt the stock 2.0L intake to supply air. Tuning induction is kind of a mystery to me and I need some info. I understand that runner length and diameter and plenum volume are all important. Also engine displacement and cam duration and target RPM are important. So, for the fun of it. Is it possible to use 2.0L intake on a 2270 with a Web Cam 163/86b. Target RPM 5000. Doing a little dreaming here, hope to learn something too. Dave |

Hi Dave,
I increased my plenum volume by about 5% and replaced the TB with one of 48mm bore size. This is on the 1.7 I am turbo-ing. Results were interesting. I didn't expect any noticeable change (still running NA right now), but after making the change it was running lean at WOT. That surprised me - I didn't expect it to flow more air, but it obviously does. These mods were more of a means to an end rather than done for their own sake. The plemum volume increase was a planned result of chopping/splicing/welding to mount the TB verticle to facilitate the turbo plumbing, and the larger TB was the result of converting to a o-ringed unit better suited to the turbo install. -Ben M. |
