We didn't notice any gas mileage loss on the GTP with the block off, but that doesn't mean there wasn't one. We did the block off mainly to keep the IC core clean, but it also keeps the blower clean. I did it on my STE when I converted the topend of the engine to the 3100 heads/intakes/tb but that was because it didn't bolt on to that intake, and the adapter plate to make it bolt on was $100 + shipping, so I put a plate on it. I noticed a huge loss in gas mileage (~24mpg on the freeway instead of 32mpg) but that has to be mostly due to the cam and the different topend.

13.957 @ 99.34 on 10psi (Gtech), 182.2whp on 6psi
But look at that improvement in your time.
An excellent trade off.

Gtech though. Got to get some REAL world times.

I remember Bill, posting a 14.5 sec @ 99. with his Gtech.....and then at WCBF04 drag competition he couldn't do better than 15.0 @ 90.

Oh, I know, Bill, it was that alternator belt and the 100 degree temps that held you back.

I know I need to get to a track but I gotta wait until spring before they are open. Not only that but I have to get there when my car has a working tranny in it. Its sitting right now waiting for tranny number 3. Tranny number two lasted a whole week and a half. However, when I G-teched the car stock it went 15.334 @ 89.74, then I took it to the track and with exactly the same setup it went 14.968 @ 91.79. The car feels like a 13 second car easily, and if I got some bigger injectors and turned the boost up to about 12psi instead of 10psi I think it could do about 13.6'* or so. Then if I put the turbo on it that I want it would be close to a 12 second car, but I don't have that kinda cash and I really want to get rid of this car before it costs me any more money.

It'* already costing you way too much $$.
You may be better off staying in the 14'*.

It was costing me way too much money before it even went fast. The engine smoked HORRIBLY and started doing it like 3 months after I got the car. At under 1200rpms it would just POUR a combination of blue and white smoke out the exhaust. So I changed the oil frequently to keep the coolant out as much as I could and filled up the coolant, and brake torqued it at stoplights to prevent it from smoking a lot, and did this until August when I finally got a chance to fix the problems. I tore the heads off and put a nice cam in it and a 3100 topend because I needed to rebuild my heads anyways, why not put better heads and intakes on it. So I did the topend to prevent the smoking mostly, but it, along with the cam & ud crank pulley, gave me a nice performance gain as well. Then after a month I finally got it running so I was satisfied with it and took my friend for a drive and the tranny started slipping at WOT above 5k. Then it kept getting worse, and it would like surge from stoplights and stuff, and it did this for like 3 weeks and then it finally went on my way home from work one day. It was the original tranny so I was kinda expecting it. Then the 2nd tranny was built wrong and worked really well in every gear except for first, at WOT it would shift out of first at 3200rpm, but I was just holding it in 1st so I could drive it and then we had ZZP'* tranny guy look at it and he told us the wrong gasket was used on the valve body so fluid was only getting to half the tranny. So now the guy that rebuilt it the first time is going to be rebuilding it again until he gets it right.

But, I realized it was costing me a lot of money when I had to do the topend, but I figured I would fix that and it would basically have a new engine so what could go wrong? Then the tranny went, and I decided I needed to fix it so I could still drive the car. After the tranny is fixed, really what can go wrong? Probably something I haven't thought of, so when the tranny is fixed I'm just gonna drive it normal, try to run 13'* once, and then hopefully sell it eventually and get a GTP/SSEi/LSS/GS or something like that, although I'll never get out of it what i have into it.

Dumbass. All 4 of us were at least a half second slow that day. Drag racing in an oven has a cost.

In defense of the Gtech, IF you have a track time to verify it against and calibrate it, the Meter can be pretty darn accurate. I proved this after a fresh calibration, on another hot day like WCBF, and duplicated my Woodburn times within a tenth. In better weather, after killing a bunch of KR, I was able to duplicate my old times.

The key is having a good baseline to KNOW whether the Gtech is fibbing or not.[/quote]

Shawn, it'* not all wasted. You are gaining some valuable wrenching experience and think of all the $$ saved by doing it yourself.
Maybe you could interest your Mom in trading up to a GXP so you can have her SSEi. Convince her it'* safer for you to have it. Mom'* are always concerned about their babies well being

Bill, are you saying that I really have a 13 sec car.
When are you going to update the 1/4 mi registry ?
