Ran My 05 Ssr At Drags Today

[TMZSSR]

Today was the Season Openner at Woodburn Dragstrip in Woodburn,OR took my SSR out to see how much the engine upgrades improved my ETs, last season my best time stock was 13.79 @100.8 mph, over the off season I added one of Phoenix Transmissions strongest trans then added AFR Mongoose 205 heads, Harlan-Sharp roller rockers, 228@.050-.600 lift cam, Kooks Headers, Radiator, Transcooler and Aux Fan from Mike in AZ, still working on getting the computer tuned to match all the new parts but Joe (2005SSR6SPEED ) has been a big help getting it close enough to run fairly well. 1st pass I left the Traction Control on and put it in Drive and let it shift itself, ran 13.51@103.1, 2nd pass turned TC off and shifted manually ran 13.24@103.85 60 foot times on those passes was 1.94 and 1.96, made 6 passes altogether best ET was 13.21, best 60 foot was 1.84, best 1/8 mile was 8.43@82 mph. All these runs were on 275/40-17 ET Drag Radials that are only 25.6 inches tall they hook up but look goofy and drop the overall ratio even lower than the 4.10 gears, there are several more sizes of Drag Radials available now and I am looking in to getting either 17 or 18 inch Drag Radials that are between 28 and 28.8 inches tall and 11-12 inches wide. Once properly tuned it should be in the 12s at about 110 mph.

Make sure it is in 3rd gear during the runs down the quarter and dont shift it yourself. Even a built transmission will be toast in no time at all. You should be able to stall it up and leave the traction control off with the drag radials no problem.

Faster is the name of the game. Play it Balls to the wall.

Joe,
I'm old school...why would the transmission be toast in no time at all by manually shifting?

In instances where there is a great deal more power running through a 4L65E it is sometimes better to leave the trans in the drive position when racing. The trans and computer can be set for optimum shift points and will produce the cleanest and most efficient shift possible. Manually shifting is fun but because it bypasses some of the accumulator circuits can be harder on the transmission and actually decrease trans longevity. The best feature about a modern performance automatic is that you can leave it in drive and concentrate on keeping the car straight going down the track and letting the trans and computer do the shifting. Do not race or launch in the Overdrive position as this puts too much strain on the input sprag and overrun clutch pack.I bet you have some 12's in that SSR once you find the best combinations and techniques at the track. Keep us posted.

When you say drive ...........you mean 3rd..........right?

Really interesting looking at your quarter mile speeds. I have an 05 6 speed I'm dying to get out to the track. I plan on it for sure this year now that I have my shift light operational and am getting the rev limiter bumped up. I'm a little surprised at the 3 mph speed increase you got from the number of improvements you made. Trap speed is usually the best indicator of horsepower and you looked to be pretty consistant just under 104. It kind of leads me to believe what I thought all along, that the truck intake is a major problem for higher performance. I'm going the other way and change the intake first before upgrading the heads. I've got a 210 218 @ .050 Crane cam in mine but with 1.8 Crane accelerated lift rockers that enhance the valve acceleration along with the .050 timing. Running your trap speed through the formula shows about 5600 rpm at the finish line. If that's correct going to a 28.5" tire will probably slow you way down unless you had terrible wheel spin with the small tires. To me your current tire gear combination looks good unless it just will not hook with those tires. I have 4.56 gears in mine and anticipate traction being an issue with street tires I plan to run. Best of luck.

Greg,
Thanks for the insight. Back in "my day" the fancy automatics had dual gate shifters for manual shifting. Technology sure has changed things. I'm beginning to feel like Rip Van Winkle...having just awaken 25 years later. Thanks again for explaining things.

Hey Guys,

Nitto has finally come through. They now make their NT555R drag radials in not one, but two 20" sizes. Either will fit on the rear SSR wheels. One is a 275/40/R20 (28.82" dia) and the other is a 305/40/20 (28.58" dia). They are both slightly shorter than the factory tire, but are the only 20" drag radials on the market.

The bad news is that they list for $ 298.00 each. Maybe that will come down some as production volume increases. I hope so, because at that price it is still cheaper to buy smaller diameter wheels and tires to put drag radials on the rear. But hey, we wanted them and now they're available.

Yes, that is correct.

Thanks for the info, this should help a lot of SSR owners looking for improved traction at the strip.

Well for the ones that are putting out a lot of hp I don't know how much the 20 inch drag radials will help, I hope they help but with little to no side wall I just don't see a lot but if that was my only choice I would try it, As far as shifting the tranny there is little use in it as you can set the shift points anyplace you want, I set mine at 6800 rpm in the 5.3, I have heard if you put the tranny in drive (3rd.) you get a little better et than if you left it in over drive, I found no difference at all running in 3rd. and running in over drive but I did see on a scan if I run in 3rd. right when I cross the 1/4 mile and let off and on the breaks I got a lot of KR, It could have been false or the way I am set up but running over drive I had zero KR and run the same et and mph, As far as the big end mph it is hard to get a high mph with the SSR I thought I was doing good at 109 with the 5.3 but the mph of the 427 build is something

Thanks for sharing your experience, there are only a few on the site that drag race their SSR's and the info you provide the rest of us will help on our outings to the track.
