ecotec swap (Page 23/98) wftb MAY 01, 11:17 PM the cherry bomb and the extra 4 feet or so of pipe have toned it down so it is just the way i like it .the cherry bomb isnt much more than a straight tube wrapped in fibreglass .without the turbo i think it would be way loud.i used the cherry bomb because it tucks underneath really well.there is room for a normal muffler ,but it needs to be centre in centre out and i only had offsets lying around .but i was surprised at how nice it sounds .i would post a video but i dont own a camcorder . i wish i could get that weekend off but i am duty staff at a nuclear power plant and we had to pick our holidays in advance .maybe next year. wftb MAY 03, 11:30 PM the bigger fuel injectors did the trick i can now run the 1/4 without detonation .i only got a chance to do one run. i blew the start (bogged it again ) 0-60 was slow , 6.69 secs ,and i missed the 4-5 shift .i also coasted after i hit 90 mph cause i thought i had covered the 1/4 and then the red light came on .so pretty poor execution on my part but i still did 14.95 @95 mph .not bad for a first try and i think as is i can get down to the 13's.it runs a little rough at slow speeds now until it warms up.i think i can now dial back the fuel pressure a bit to solve that problem .i had the day off wednsday and the reason i only did one run was i could not believe all the the people out on the roads .i wont do a run unles i can find an empty road ,and it was a nice day so i think a lot of people were playing hooky from work .days off during the week usally mean not many people out and about but not wedsnday .but good progress was made . wftb MAY 05, 05:01 PM i got in another run with the bigger injectors .this time i dropped the clutch at2000 rpm ,a little spin and off i went .i set the g tech for a 6000 redline so i wouldnt hit the rev limiter .the results were much better; wftb MAY 05, 05:11 PM i think i can get into the 13's in the next run or three .using the 6000 redline cost me a bit of momentum ,i could see by the horse power result .but my 1/4 mile acceleration curve was a nice curve without flat spots like my previous runs .so the shifts were good .i am getting more summit goodies next week .100 psi pump and vortech 6:1 mechanical fmu .i want the 12's ! wftb MAY 05, 07:02 PM that was 14.1@98.6 mph ,sorry about the pic. Fosgatecavy98 MAY 05, 07:45 PM Looking good!!! I got some questions for ya when i get more than 30 seconds lol.. wftb MAY 07, 04:23 PM i solved the detonation problem .pretty simple fix .i had set my meth injection to maximum at 8 psi .this was too high .i set it to start at 2 psi and maximum at 5 psi and no more detonation during 4th or 5th throttle roll ons .uses a lot more washer fluid now but no more worries about connecting rods .i still have a slightly rough idle and it doesnt run smooth until it warms up but i am hoping to fix that with the fmu and a lower idle fuel pressure .but the big improvement now is that i can put my foot in it any time without worry about detonation.

What H2O injection system are you useing? The last time I looked at them the duty cycle was only like 60 seconds. wftb MAY 07, 10:27 PM i am using a snow stage 2 system .it is electronicaly controlled with a boost reference point .it will continue to send in water meth as long as boost levels are above or at the set points .if i spent a minute at full throttle ,around here i would run out of road. Fosgatecavy98 MAY 07, 11:36 PM Congrats on that fix!!! BTW sunday I got mine running, not good but it moves under its own power! I believe I am the 3rd now on the forum with a ecotec powered fiero
