Slowest CanadianTurbo SS 12.74 @115? Best I could manage @ Grand Bend Friday Sept 30th was:
60' ...... 2.190
330 ..... 5.708
1/8.......8.446 @ 89.92
990.......10.794
1/4.......12.741 @ 115.81
So, now should I go with 16" rims and slicks or 17"?
Specs:
98 Camaro SS, 32,000 km. (5000 km on turbo Summer Street only)
Stock Motor (except 918 springs old stock springs had 65 lbs pressure!)
single log manifold kit T-63 (piping made by Stainless works for a Non Sponsor)
7psi on MBC
Borla exhaust QTP cutout no cats
Upgraded fuel pump and 42 lb injectors
SMC methanol progressive methanol (on @ 2psi, full flow @ 10 psi)
20 degrees timing
Moser 12 bolt 3.73
Spohn torque arm, relocation brackets and LCA
Spece 3 clutch
SLP SFC, STB, Eibach pro springs, Bilstein HDs, Energy bushings
AMW catch can.
Stock somewhat bald rear Eagle F1 tires.
(peak 448 rwhp, 543 rwtq, 90 degrees 100% humidity, 600ft
60' ...... 2.190
330 ..... 5.708

Your 60fts are terrrible.Guys are our track are getting great times with the new et street radials. Also do you have a two step to build boost...if not get one!!
Your mph is not very good either ,what boost is that dyno at..Buddy with 413 Na car gets better mph at our track at 1700 feet. Ok so that dyno was at 7psi? About limit I would want to take the stock bottom end to.
Do you have wideband on their..how is your tuning..? What is altitude of your track?
Just throwing out some stuff. Buddy has an sts lt1 car stock engine but no times yet and I have had several turbo dsms and turbo motorbikes.Am thinking of turboing my 99 trans am in next year or two buying parts that I need now. Both lt1 buddies that I know ,one with ati procharger and one with the sts blew their stock ringlands off by getting a bit greedy. Be careful on the stock pistons. Word to the wise.

Yes 60' time is terrible: Needs proper tires I know that.
1/4 mile MPH is low as well. Poor tires, cold track, inexperienced driver. Better tires,and some practice on a warmer day should improve that. Car is heavy with the mods I have. So that will hurt times too.
Boost is 7psi (max I want to go on stock bottom end). Will a two step have any value at this low boost level?
Track Elevation:642 ft. above sea level.
So as I see it now two biggest weaknesses are tires, and driver skill.
I'll look into a two step. Who do you recommend?
Thank you.

Harlan used to make one on ls1.com boards but think he stopped. Might be able to find one used. Not sure if you can do it with programming like hp tuners or ls1 edit or any of those. I can do it with software on my 97 turbo awd talon and had it in a chip on my recently sold 92 talon awd turbo.It worked well and you could leave much harder and get better 60fts but never did track race the 92 and the 97 is apart getting motor done up proper to handle massive boost.
So just ask the other turbo guys pretty sure also they are built into some ignition systems for the lt1 but the ls1 don't work with them.
I think a two step would still help at your level. The tires might help first and the most though.Mabye try to borrow some off a buddy even. The new et street radials are awesome.
What are you using to tune your car currently..?

Your trap speeds should be higher with that much power... 448 rwhp & 543 rwtq should give you at least 120MPH in decent air... with my heads and cam car Z28 that only made 440HP/410lb-ft I ran 121MPH in good air at the end of last season... myabe go to another dyno to make sure you are putting out as much power as you think you are...

On street tires my 511rwhp only went 118 in the trap. 1/2 an hour later with M/T DR's it went 122. You need traction. This past Friday with better prep at TMP I went 12.3@122.2 but you need grip and a very gentle foot to get that kind of torque to hook on a street tire. I think you have the power, just no grip at all.
When I had Eagle F1's that were that worn they had as much grip as a de clawed cat on linolium. I hated that tire.

Some good points Dale, but I still don't think 448 rwhp + 543 rwtq = 115MPH... think about it, this summer my full weight Z28 ran 116MPH in 3000FT DA and it's only making 409RWHP now... That's some serious power this guy is making...

That was the same day I did 118 too. I had pretty new tires as well. You have a lot less torque easier to plant plus that is one of the stickiest street tires you can buy on your car.

Thanks for the input guys:
I had it dynoed last year at ARE in pickering 5 psi 390 hp, 470 ft lbs by Kevin
Not sure if they moved this dyno to Autoworx. But this year @ 7 psi I got the 448 hp and 543 ft lbs tuned by Pete.
Given those two dyno sessions, Even though a Dyno jet, I think it is making more power than I am able to plant.
Experience matters a lot, and this is my first time to the track in over 15 years! So low 60' and trap times by your standards are understandable. I need to weigh the car, but given my mods I think its FAT.
But I had a great time and am not disapointed. I'll be back.
I would appreciate your recommendations on rubber for next season.
ET Streets on 16 inch rims? What size? Since I am 2 hours from Grand bend I suppose I will transport the tires and change them out there, Or can I drive them to the track?
Thank you.

It's true that you need traction to get a good ET, but your car should MPH well even if it's spinning... for example, my stock motor Z28 with exhaust work went 111MPH spinning on F1's... with a 100HP dray shot it went 121MPH. Earlier this summer in 30+ degree heat my wife went 116MPH the 1st time racing her 409RWHP H&C Z28... some thing does not add up with close to 450RWHP/550lb-ft and 115MPH... I would re-dyno to confirm all the power is there... just my 2 cents!

Most guys seem to be very happy with et street radials and getting great times at our local track.For cheap some used et streets or bfg drags could do it for you. Nittos at your power level are likely not going to do it. You have the rear end..might as well use it!!
Oh I also noticed you have 3.73 gears. Might not be the best for turbo car. I have heard too much gear won't let the car stay in boost as long as maybe a 3.42 or 3.23.
Not 100% sure on that though as just been reading lots on boards.
If your 60ft is not great after the tires then the two step is likey what you need.
One other question is can the spec hold the power you are making or are you getting full power out of it. You might even need to upgrade clutch to something like the textralia. A slipping clutch can hurt mph as well. I guess get the tires first. Most guys buy them for 16 inch rims..and you could drive et street radials to the track if you had to just be careful in heavy rain.
If you are trying to save weight then some 15 inch rims might be a good choice not sure what offsets you need or if you have to trim the calipers etc. Most guys with fourth gens around me are running 16 inch rims and think 255/50 /16 or something tires.
I am sure you will be deep in the 11s once you sort things out and would expet around 120 mph traps or better out of that setup.
Good luck!

Do you have an M6 or an Auto, I don't see that anywhere in your post? An M6 will MPH lower than the HP would suggest because you lose boost when you shift.

In that case, good show for your first time at the track in a long time. Go back some more and get some more practise and shift real quick to keep the boost up.

It is great you got out and had some fun at the track for the first time in so many years!
2.0+ 60foots really hurt your MPH at the track. There are so many driver and traction variables when running on street tires at the track that a car's performance is never truly demonstrated.
A set of track tires, some launch practice, and some shifting practice and you will be shedding off time quickly.

I was at Grand Bend on the 30th also. I was driving the silver Z06. I remember seeing two SS's, one blue, one silver. I didn't get a chance to see either make a pass as I was too busy waiting in line. I ended up running a 12.18, 12.16 and a 12.04@115.
