thanks for clearing that up for me. i am trying to learn as much as possible about tuning before i turbo. i thought that it was the other way around (boy i feel smart), meaning the lower the number the leaner you are.

i have seen you around on other forums, and wondering if you have tried the propane injection yet ( as it was mentioned on another site). i was wondering if it was worth all the headache.

sorry, not trying to hijack your post. just curious.

 

No problem at all. I've not worked with the propane yet. I was thinking of getting into it since it's cheaper than gasoline now. The kits are around 1000.00 depending on the power level. I know that Propane has alot more octane than regular fuel which helps us on boosted vehicle's. It would be around 110octane if you compare it to gas. (approximatly)
Timing is different as is several other things.
Apparently from what the other guy said you do the opposite with Propane... you start lean and work to rich. A overly rich propane setup glow's the intake valves and they warp.
I'm not a expert on this but I'd love to try some on my Nissan turbo car and learn some about how it works!
The guy on the other board seems to have worked with it quite a bit. You might want to ask him some questions about it if your interested.

Looks good, Scott!

I forgot I had an account over here.

 

i'm gonna have to get my 98 s-10 back this looks way to cool to not do i think it will be very interesting in a 2wd 98 s-10

 

It's been over a year on the Jimmy Turbocharged. Over 13,000miles city/highway combined. We drive it on vacations and my wife drives it daily. We still get 2-4mpg
better than the truck get's stock. It's a blast to drive and all is going very very well with the truck.
I just purchased some used stock Typhoon wheels for it from a fellow Sy/Ty member that got some corvette's for his.
It lowered the truck 2" by just switching tires/rims and makes it feel much better.
Anyway... Thought I'd give you a update on duribility and dependabiilty of this
setup on a daily driver truck,
Scott~

 

Is that 2 - 4 MPG better than what yours got, or 2 - 4 MPG better than the sticker said it's supposed to get

Good to hear she's running good!
Might be something I can look into, now...
Though, a V-8 swap would be easier when it comes to the computer programming for me... Since I have no performance shops to do the tuning around here...

 

2-4mpg better than we were getting before... We clocked it this summer when it was 90deg outside going on a trip. We got 21mpg with the A/C on all the way down loaded with all of us and luggage.

I didn't lean it out it's still in closed loop at 14.7-15.2afr while driving.

She was going to race it with my car up at Stanton but got sick the night before... I sure was looking forward to knowing what that truck will run. I'll find out next year when her Typhoon is finished up and I'm driving the Jimmy every day!

Hmmm... I wonder if I can get a 2 - 4 MPG gain...

I already get 21+ MPG on the highway...

Probably helped the city mileage a bit... The 4.3 might be torquey on it's own... But Jimmy/Blazer's are heavy, lol

 

i will be putting a turb on my 98blazer in jan or feb. you can use any turbo but you will sacrifice top end with a smaller easier to spool turbo vs a slow spooling big freee flowing turbo with lots of top end. if you just want something that is fun on the street then get a smaller one but if you want to try and humiliate the v8 guys then slap a big one on lol also the tbi setuops will work great with the right tune and a 2 bar map sensor. biggest problem i think i will have is the fueling ...damn little spider injectors ..i think i will go the 7th or 8th injector route

 

oops sorry guys i was still on page one lol
