boost was 22psi
air temp at track shows 73 ,wind blowing sideways across track
tires were 255/60 15 MT et street radials from micheals auto at 19psi
vehicle weight with driver met rules at 3582
87 gn hardtop all metal, all power options and cold a/c, only mod for weight is left the spare out (ran 3/4 tank of fuel instead ) and factory front and rear TType alum bump supports which we just did on murphs sleeper and found is only a 19lb savings for rr bumper over the steel support

So...even a racecar with a stock turbo on it is still.....SLOW...(Sorry Don...Beat you to it)

So..The stock turbo challenge was won with a time of 12.74?..Man...That is sad...lol.You should roll the money over to next years event.


The stock Turbo Runs in order.....

Slow...

Real Slow...

Unbelievably slow...

Did I forget to shift out of Park...

Holy Christ,I cant believe how slow that was...


It's a shame I still didnt have TTA#343,It wiped up all those time including Murphs 1 run wonder..

I never thought it was running that well,Because I thought it had a 49 on it...wasnt until years later when I was going to have Paully rebuild the Turbo that I found it was a stocker.I have some video somewhere on my computer,But haven't ran across it yet.

11.7x@11? no deductions.And it did it regularly,Not once...And put into retirement.....Still SLOW though.


Did Murph bring The Money with him to the Event?Can I see the pictures of Him handing you that Big 6'x3' cardboard check,And what will the bank say when you try to deposit it...

On a serious note...it looks like everyone had a good time,I wish I could of made it...But the schedule didn't allow any time for it.maybe the next one.

And almost everyone made it home with a running car.(Sorry to hear about the HG Tommy).

Yup, congratulations Pauly.

It had been over two years since I had a stock turbo in the clone. The car had been running well on the 44 so I figured it would do pretty well. As mentioned by Paul before, the stock turbo was put on it almost by chance since the 44 has a little wobble in it. I set the boost to 22 and really the only adjutments I made were to timing after pulling all the fuel out of my chip. A 12.29 on the first pass was pretty good with a 1.68 60ft. Unfortunately Paul made his first test and tune pass two cars in front of me and I saw his 12.14 and knew what it meant. All I needed was a 12.23 to beat him. My second pass yielded a 12.32 with a 1.67 60ft. In the third pass I went 12.42 after I went for broke on the launch. I spun like crazy but still got a 1.81. A decent 1.6x 60ft would have got me close. I was shooting for a low 1.6 or high 1.5 60ft. With the stock sway bars it may be pushing it. Slicks would probably help.

I guess the stock turbo challenge didn't generate the interest I was hoping for, but we did learn a few things. It doesn't seem like the heads or cam helped the ET much, if at all. The stock turbo doesn't need the high rpm or extra flow. Advantage from a big intercooler still remains to be seen. Paul didn't really push the boost high enough to see if it would help. He did run better than when he had the dutt neck on it, but that may be more to tune than the intercooler. A back to back comparison would probably show on a low 12 sec car if there is any advantage. An intercooler with a very low pressure drop would likely have the best shot.

Paul had a best of 109 mph and my best was 108 mph in the clone. My GN went 110 mph. All were at similar boosts with Pauls being the lightest car, the clone being the heaviest and the GN in the middle. All were within 200lbs of each other. The biggest contributor to mph may be the converter though. The mph directly parallels with the converter size. The GN had a 12" converter, Paul a 10.5", and the clone a 9.5".

Weight reduction is probably one of the bigger factors in obtaining a good ET with the stock turbo. My GN gained almost 4 tenths ET with 2psi boost and a 200lb weight reduction. I could probably get my clone down to high 5600s weight with a couple weigh reduction tricks and by being smart and running only a 1.2 tank of gas or so.

A good 60ft is definitely key to getting a good ET with the stock turbo. All of the good runs by everyone had at least a 1.6x 60ft. The main thing in common with all of the cars were Mickey Thompson drag radials. Pauls car had the most suspension work and managed a 1.64 60ft while my GN has the least suspension work and got a 1.58 60ft. There are some features in the chip the GN has in it that I will be testing in my clone soon to see if that is one of the reasons the GN 60ft'd so well. While keeping the stock front in rear sway bars in both the GN and my clone, another thing both had in common was that all of the bushings in the rear control arms were upgraded to Energy Suspension bushings. This included the lower and upper controls arms plus the ears on the rear end.

I'm not sure yet if Paul and I will continue to shoot for 11s on a stock turbo. With the cooler air coming up, it might be a good time to try. With a little less weight and a better 60ft my clone should be close.

I've now run good times on the stock turbo in all three of my cars:
White T:..12.31@107.5, 1.67 60ft
Clone:.....12.29@107.4, 1.68 60ft
GN:.........11.97@108.0, 1.58 60ft

Once again, congrats Paul and thanks for all of your help.

Well, Pauly collected the payout from me last night. He was so happy he swapped my stocker for the TE44 with the upgraded .85 housing on the clone and I can't recall him complaining even once.

Paul, you should also be getting a MAGNA tshirt and hat from Jim, a $100 from Shawn, and another $100 from Roger.

I was thinking of doing another challenge like last year, but I don't think there are enough people.

Instead, I will have a standing offer to pay $500 to any MAGNA member who beats my 11.97 ET on a stock turbo with the restrictions and corrections below:

- Stock 86-87 Turbo. Mild porting ok, but housings and wheels must be stock.
- Must be a Turbo Regal similar to the 86-87 chassis. No TTAs or hybrids. Clones ok.
- Stock 109 block. Rebuilds with boring ok. No strokers.
- No nitrous. Primary fuel must be gasoline. Alky ok.

The following ET penalties will apply for the following mods:
- Weight with driver should be 3500 lbs. For every 50lbs less than this, a 0.05 penalty.
- All other mods ok.

So there are pretty much no restrictions now. Its pretty hard to get under 3500 with driver unless you've made some obvious weight lightening mods, so it shouldn't affect anyone unless you have a stripped racecar, etc.

In the event that more than one person goes faster than 11.97, the lowest ET turned by the end of the year will win.

The ETs from any track that MAGNA races at will count. So this includes Englishtown, Atco, Cecil, and 75-80 Dragway.

Finally, a second MAGNA member must be able to verify your timeslip and combo, or vouch for you.

Nice!

Murphster, you have a PM.
