Supercharger Questions

[fhornerguy]

So I recently installed the TRD S/C on my '97 SR5. It had about 125000 miles on it, and now another 500 with the S/C. The install went great and only took about 5 hours to do including some prep work. But I just have a couple questions.

That friggin power steering line: where the heck does it go? I can't find anything online about it, and there are no other vaccuum ports to attach to. Do I just cap it? (The intake is the stock setup with the deckplate). Any thoughts?

My other question is in regards to the performance. Obviously, with the ECU adjusting, the first couple of days were a bit rough ie. the tranny was shifting all over the place. But after a couple of days, the results were tremendous, and I couldnt be happier. In the last two days however, there have been some problems when running it cold. When I drive to work in the morning there is a large hill right by my house, and when trying to accelerate up it, it makes almost no acceleration at all. Even with the pedal on the floor the engine feels like its struggling to even reach 3000 rpm.
At first I was worried that it was the transmission, but it does the same thing in N. When revved, it is not smooth at all, and feels like its sputtering and sluggish all the way to redline. However after its been driven for a while, everything runs properly. So Im at a total loss as to what is happening, and have not driven since to try and see whats wrong, and prevent any damage if any is being done. Any thoughts?

Thanks guys

You probably need more fuel. Many claim (and I believe them) that you need fuel mods to make the s/c work well. Others have said no.

Two different kits available for the TRD 7th injector or the URD fuel mods.

i have a quick question myself....

does the s/c increase fuel mileage? i only ask because my family own's a toyota previa which came w/ the s/c and when i drive it, i put less pressure on the throttle and usually when i drive my runner or another car i have to press on it a little more...

please let me know because i plan to put in a supercharger in my runner myself!

Well...here's how I see it. Before I put the S/C in, i filled the tankwith premium so that when it was installed it would be all ready to go. While driving around for a couple of days on premium before the s/c, the milage was surprisingly much better (about 17.5...still not too great but compared to the 15.5-16 its better).
So I figured that when the s/c was in, the milage would drop a bit (in part due to the fact that its a tee bit easier to put it on the floor with that much power, and the simple fact that the ECU adds more fuel to counter the increased air). But because of running premium, it would stay right about where it was before i put it in.

So, long story short, the milage has remained almost exactly the same, but it really depends on how you drive it.

PS. If you do put one in yourself, drop me a message and tell me if you figured out what to do with the power steering line (haha). And if you have any other questions about the install feel free to ask. Its sooo much more rewarding to do it yourself. Good luck!
