Fosgatecavy98, I had a build thread, but then I got sent of to Virginia for training then when I came back the big wigs at the shipyard in Bremerton decided that everyone needed to work 115 hours a week in preperation for getting all the work done on the Uss Abraham Lincoln. So we've pretty much been working every other day for months on end. I've been taking pictures though. I'll be putting them up sometime. The most progress I made was the first couple and the last day of leave I took. I started fabbing the mounts yesterday, have some nice pics such as this:

Now I'm off to work again, hopefully I get to come home tonight.

i relocated the blow off valve to the top of the air box because i was getting the deadly "whistling sewing machine" sound that meant it was not opening when i closed the throttle to shift .i capped off the hose where the bov was before and tapped that plug for my boost guage .since i have still not received my new fpr and methanol injection kit ,i left the hole open so the car builds a small amount of boost for now .even with the hole ,it still builds enough boost to cause knock at about 4500 rpm.but it is much easier to drive know.i picked up a gtech pro ss to guage the improvement once i tune the setup.no need to drive a 100 miles to the nearest drag strip now

it started snowing 3 days ago and hasnt stopped.so the fiero is back in the garage and i decided to clean up the turbo plumbing and get rid of the stock air box .the air box (now that i have had a good look at it) only serves two functions :a place to mount the maf sensor and vacuum line to the fpr and intake noise reduction .so i dont need it anymore and it takes up a lot of space .with it removed you can see how there is lots of room for the supercharged motor .the airbox sticks out from the engine a lot further than a supercharger does.some of you may be wondering why i am using plumbing pipe for this installation .simple: its cheap and it works.i didnt want to buy fancy silicone elbows and chrome pipes until i am satisfied with the setup .so i have less than a 100.00 in my turbo plumbing so far and it still isnt exactly what i want yet ,but it is getting closer.

i got my water/methanol injection system today ,and my aeromotive LT1 style fuel pressure regulator .the fpr responds to boost as well as vacuum ,something the stock one cant do .the injection system comes with an electronic variable controller and a 150 psi pump .i have to work tonight so installation day is tomorow .so i will finally be able to use some of the boost i have available .i hooked up my Gtech and i will post some numbers when i test it out.cost of the turbo setup so far :
turbo 599.00
plumbing 100.00
fpr 159.95
snow injection kit 389.95
subaru gaskets 48.00
plate steel 19.00
misc nuts an bolts taps drill bits glue ~100.00
oil evac pump 116.00
braided line , rubber hoses , clamps and fittings ~100.00
total 1631.90 so now i have spent more on turbocharging than the whole engine /tranny swap cost .pics

i have spent some time tuning the motor using the aeromotive fpr and the methanol injection kit .i can now run it to the redline in first and second gears without detonation .once i hit third gear the pinging starts at 5000 rpm .so i am not ready for the drag strip yet .i have some 32 lb fuel injectors on order and that should get rid of the last of my detonation problems .the car runs amazing well .it idles a little rougher than it did before but out on the road it is very smooth .and it is still being controlled by the stock computer .i am very impressed at how well this engine runs without much in the way of tuning .
did i mention the car is fast? it really throws me back in the seat now .i hope to get a 0 to 60 time with my gtech tonight .there is a nice flat stretch on the way to work that should work to get a run in.no one lives along this stretch so it wont attract attention .owning the only running fiero gt in bruce county does have its disadvantages .everybody knows whos car it is if i get reported !
the whole driving experience is different now .this is my first turbocharged car .it is really neat to hear the turbo spool up and the rush of air going to the intake is something i had not experienced before .the sound from the blow off valve when you shift adds to the mechanical mayhem going on now. it is a little noisy without a muffler ,so i hope to add one soon .i ordered some tight mandrel bends from summit and these will arrive with my bigger fuel injectors .

Have I told you how much I envy you yet cuz your my hero. Cant wait to hear the 0-60 times,

I'll bet its in at least the 6 second range
wftb APR 18, 11:37 PM
first run i bogged it off the line and ran 0-60 in 6.62 sec.second run i smoked the tires !(kumho ecstas 16"245/ 55r)i need a little practise at drag racing so i am going to grand bend when it opens.funny thing about my first ran is i hit 58 mph in the mid 5sec range and then the graph flatlined while i shifted to third .on my next run i am not going to use first gear and see how i do .second run was bad(7.6)but it said i produced 189 hp at the wheels.
Fosgatecavy98 APR 19, 12:56 PM
Thats quick! I would assume you may be able to get into the 5 second range soon. Get some videos!!!

thanks for the replys ,fosgatecavy.i think there is more interest in what we are doing over on the ecotec forum ,but i can only post pics here for now so i am still going to post most of my stuff here for now .i do have a lot of people reading this thread ,just not a lot of posters .
i did two more runs today .first i tried a second gear launch .that didnt work ,too much bogging .0-60 =high 7's .then i tried another first gear launch .still bogged it a bit ,better than yesterday ,but still room for improvement .but launching that little bit better shaved over 4/10's off my time .i did a 6.19 0-60 time .with some more practise to eliminate the slight bog coming off the line ,i should be able to get in to the 5's .the hp figure on that run came out at 160 .i then looked at how i have the gtech setup and realized i forgot to add my weight(185) to the weight of the car .so hp is probably on the low side .i got the highest hp (189) on the run that i spun the tires on.pics of gtech:


on the way up on the best run i did 0-10 .647 , 0-20 1.587 , 0-30 2.367 , shift ito second @34.8 mph 2.84sec .graph is then a flat line until 3.425 sec .what seemed like a quick shift actaully stalled my acceleration for almost 1/2 of a second
0-40 3.910 , 0-50 5.034 , 0-60 6.193 , shift into 3 @61.4 mph 6.433 sec not accelerating again til 7.102 (i gotta build an automatic car!) a waste of 7/10's , 0-70 8.505 ,0-76.6 9.608 secs.that ended my run cause thats when the detonation gets too bad to keep it floored .
but what a great tool the gtech is .it shows all the areas i need to improve on and you can anilyze to no end with all the stats it spits out.when i go to the strip ,the gtech will be along for the ride .
i am going to go on some car mag sites and see by comparison what a 0-60 time of 6.19 equates to in the quarter .it will only be ballpark but keep in mind on each of these runs to avoid detonation i use a 1/4 of my cooler bottle .so when i get my larger injectors i will run quite a bit faster .
wftb APR 19, 04:02 PM
i did some reviewing of the data of my run that i got the wheel spin on .i forgot that what totally ruined that run was that i managed to hit the rev limiter at the end of first gear .my 0-40 time was 2.789 sec .that is a full 1.21 sec faster than at the same time as my 6.19 sec run.maybe a little wheelspin is the way to go afterall.
