Let us know what happends to your dyno runs after 3-4 pulls. BTW I picked up MAJOR hp above 4000rpm after I dyno tuned a SCd Escalade.

Make sure your AF is not to rich up top, that would cause a big loss in hp. Summer is coming up so tune conservatively.

After you drop to 3.125" you'll crave for more boost.. Just jump down to 2.87" and save on the labor for next time

 

No way dude. I don't want to push more then 10psi through my stock injectors. The 2.87 slightly overspins the blower at 6300rpm too. I want my blower to last me at least another 15,000 miles. According to my boost gauge, I already see about 1psi of boost at ~2777rpm.

Maximam: He is going to call me back to set something up for the end of this week. I'll definatally let everyone know afterwards.

 

Think of it this way. After you wear out your bearings. Instead of doing a blower rebuild you'll have some incentive to go turbo instead

 

Personally, I'd get whatever problem you're having worked out before adding more boost. Could cause problems...

 

Ya.....one would be ~$400, and the other $4500. Besides, my Supercharger owns the Turbos remember?

 

Driving skills?

 

Negitive.

 

ECU codes?

Are you that freakin lazy?

 

definatetly going with negative...


Theres really no "skill" in dropping your car into 3rd and gunning it. I could see if it was from a stop, then theres lots of skill involved in the launch and shifting and timing...

You went from 70-100 and put 3 cars on him. 70-100 is about a 5 second race, 3 cars in 5 seconds is pretty good pull. 40-70 is a 3 second race. 2 cars in 3 seconds is alot. Sound to me like you are hammering him pretty badly but you just had high expectations, too high.

 

 

I know, but it just seems like I should be putting more then that on him since I have ~90+HP on him.

 

90 PEAK hp. And if you are racing, why do the both of you insist on slamming into a lower gear when you know your gonna race? Much easier on the tranny just to be in the correct gear, THEN go. Kapeesh?

 

Yes, but I should be pulling to that PEAK hp (redline) a lot faster. The spool was slow.



Yes sir!!

 

Did you check the ECU?

 

i never slammed mine into 3rd. We were on the highway cruising in 5th, as soon as he got beside me i put it on 3rd and then began the race after we honked 3 times...


And craig, if you dont get all this $hit figured out, we should just race from a dead stop next time i head up there the 14th to see what you can put on me, since your mommy wont let ya head to the drag stripp



Eric

 

June 5th *****.

 

 

Whats june 5th?!? HIN is the 14th....

hmmm, got something planned?!?


Yo daddy,
Eric

 

I've been busy lately with finals, i'll check it ASAP though. If the ECU can detect a bad knock sensor, then why doesn't it trip the light like it does for other problems?

Delio: Yes, lately i've been lazy (tired would probubly be a better word)

Eric: Check your PMs

 

KS does not trip the CEL...this has been discussed hundreds of times over. It is not critical to emissions or the car blowing up, the motor will pull all sorts of timing, and the engine will run, like crap. It is by design to not set off the CEL you have to manually check the ECU.

 

List of possible problems that could all be checked in an afternoon at home:
ECU codes
Compression check
Inspect INSIDE of Ypipe flex
Inspect INSIDE of cat

Do all of these things before you go to a dyno. By the way, how do you know you have a 90 HP advantage if you have never dyno'd?

Until you have done all these things yourself, the rest of us can't be much help.

 

I'm going outside to do that now....

Car's going into inspection tommorow at 11am, so i'm sure compression checking will take place.

When they installed my Ypipe it was a very tight fight. I mean it's screwed on SNUG. There is no way i'm going to mess with it.

Becuase, with a 3.33" pulley, that's about what I *should* be making.

 

Just did the ECU test, 0505. So according to my ECU, everything is normal.

 

Compression test at inspection? Are you running a fever dude?

 

I have the little compression meter in my car, me and Tom will do it tommorow morning. Were going to take off the blower and inspect it among many other things. We can't get into electrical though, but that doesn't matter becuase it reads fine.

Am I running a fever or is my car?

I also plan on dropping in the 3.125"/8:1 disc as I have been planning on it for a couple weeks now. I hope we find out the problem first though or it probubly won't happen.

Oh yea, there is are a couple tiny knicks on the other rib of the 3.125" pulley. One doesn't cut into it, but the other took a spec of metal off. (very small). These are really tiny, but the one is concerning nonetheless. Does the pulley have to be in PERFECT condition, or should I be ok?

 

for mine....I sanded it down and make it smooth so it doent eat my belt.

 

Hmm...interesting!

 

Well he changed out the 3.33 pulley for the 3.125". He said he heard detenation past 5000rpm with the 8:1 so he put in the 12:1 disc. He said he didn't want to be responsible if my engine blew. Well, I felt no power gain whatsoever and I blaim the 12:1 disc for this. So I got home and two days later (today) and swapped in the 8:1 disc. I can feel a noticeable power difference. It's not as big as I expected, but it's there. Feels like maybe a ~20HP gain or so. The RPMs climb slightly faster. BTW, I got no detenation. I am still pretty convinced that my car isn't putting out as much power as it should, now the only thing left is a dyno. Should one feel a huge difference between the 3.33 w/6:1 and 3.125 w/8:1 ?

BTW, Fuel pressure with the 3.125 and 12:1 was ~38 at idle, and is about 1 psi higher now with the 8:1.

 

Compression test results?

 

There wasn't enough time. Another good sign that it's not the compression is the breather valve isn't leaking any oil.

Just drove the car for the second time today and it feels significantly faster. Something in the neighborhood of ~35hp. When I first threw the 8:1 in this morning and took it for 4 WOT runs, it didn't feel much different. But now, 3-4 hours later, it feels significantly quicker. Does the ECU have to adjust to the changed flow? Becuase I nearly swerved off the road downshifting into second @42mph, and the RPMs pull quicker.

Tom says I hit 9psi but I bet I'm hitting 10. Gotta get someone to drive with me to look becuase going WOT demands eyes on the road.

 

id be glad to observe your boost gauge craig...

Or perhaps YOU can look at the gauge while i drive

hahaha


Eric

 

So you had enough time to up the boost, but not check the plugs and do a compression test? That's not smart. If you think you have problems (which you seem to), your compression is the first thing you should check!

That doesn't mean your compression is fine. There are lots of places you could be loosing compression. Not just the one.

 

I dont think FMU affects idle fuel pressure. I wouldnt use a 12:1 after seeing my fuel pressure hit 112psi at WOT with an 8:1.

 

I completely fail to why everyone, Craig included, seems terribly surprised by the outcome of this race. I believe Neal was right on the money when he said pulling 3 cars in a 70-100mph race is doing pretty good. I'm my book that's nearly running away from your opponent. If the race would have ended at 120mph, I wouldn't be surprised if he would have pulled a total of 8-10 cars. The first race was completely pointless because Craig let him get a jump. That .5-.8 seconds is HUGE I hate to tell you. FYI, I've run my buddies automagic 99 Z28 (13.7@104mph) on occasion and he puts about 3 cars on me from 65-95mph (about the same kind of race).

Craig, you're looking for problems THAT ARE NOT THERE. For those us that go drag racing legally, we understand acceleration curves. You might be cranking out 90 more fwhp, but that PEAK like Jeff pointed out. Peak and average gains are completely different. If your SC had elevated your entire curve 90fwhp, the difference in performance would be staggering (LS1 like in nature). Your car clearly showed it had more power because it was pulling away so hard. I'm sorry, but you don't drive a Viper therefore you're not going to easily lay waste to a like car with 90 less peak fwhp. It's just not possible. If the race would have gone to 120mph, the distance would have made you a believer.

Right now, you're just wasting your money and looking for problems that aren't there. If you really want to be quick, dump those rims. Like others have pointed out, 50lb rims kill your performance. There's a guy in the KC club that's running 2k SE 17s (51lbs) on his 98 5 speed. He's .4 and 3mph slower with those rims compared to his stock 16s (42lbs). It makes a huge difference regardless if you're at a roll or taking off. The reason you hook better is because those weights are bogging out your motor.



Dave

 

Actually, that was just the WSP B-Pipe fix and a Stillen Exhaust.

I guess that counts as a cat-back.

(Pssst.....and I'm not Auto anymore)

IanS

 

oh yea....forgot that you have the fix instead 2.5" cat-back


congrats on the 5spd swap~ it must feel much faster than the auto.

 

The thing that bugged me was how slowly I pulled, but I guess that's just one of the perks of this kind of boost. I was stedily walking him though, just not as fast as I had thought. And I know headstarts can make a huge difference, but were talking about a high 14 second car here. That Z28 story makes me feel a little better.


Hmm..



Dave, my rims weigh 24lbs. a peice, which isn't bad for an 18x8.5 rim for the price it was. So, with those and my 245/40/18 Nitto 555's, my setup shouldn't be any heavier if even as heavy as his. What mods does he have BTW? Wouldn't you agree that my rims would have a much more significant effect on a n/a maxima then the same max @10psi? Even though it's linear boost it should still negate the effects of a heavy rim...

If I were to go back to stock 15" sawblades the results would be bad. I already can spin the tires in first from a roll, and usually spin into second. With the stockers I can only imagine my traction problems. Besides, I am not ALL go, I love the way the rims make my car look and the compliments they bring...
