Hi,

I went to Capitol Raceway yesterday and was able to run my car 11 times. Weather was more than ideal: mid 30s and low humidity. My 60’ times from last week’s excursion to Cecil County Dragway (first time I ever raced a car) were dropped significantly from 1.9-2.1 to 1.7-1.8, therefore my quarter mile times were vastly improved. 1/4 trap speed was slightly higher on most of the runs, but 1/8 trap speed was a bit slower. Weird. Anyways, all my runs were well below 12.5s, and at the end of the day I thought the unthinkable: 11’s were at a glimpse. My best run was the 9th one, and the best trap speed was the prior, #8. Oh, and please, keep in mind that I'm running skinny 205/50 snow tires and they are definetely hurting my times.
Here are the numbers for runs #8 and #9. No race gas; straight 93 pump gas and a quarter tank left.

Run#8:

60’ 1.884 (worst launch of the night)
330 5.321
1/8 8.062
MPH 88.83
1000 10.442
¼ 12.434
MPH 114.81


Run#9:

60’ 1.708
330 5.008
1/8 7.751
MPH 87.53
1000 10.106
1/4 12.082
MPH 113.78


Kudos to Nick from Precision Dyno for making my car this fast with just bolt-ons. However, I'm still trying to understand why is my car so fast with just 300 whp and 290 tq. My Evo was the fastest among a handful of Evos whose owners claimed 370+ whp but were almost .5 sec slower than mine, most of them with full suspension setups, sticky tires, many years of experience drag racing bla bla bla ... I addressed my thoughts to Nick 2 from PD and he insinuated to me that the Mustang Dyno at the PD headquarters throws underrated numbers...oh well who knows. I'll be bringing my car shortly to PD in order to get the AI kit and then I'll be done with the engine. Now its time to upgrade the suspension. Handling wise, my late Mini Cooper S with KW coilovers would have destroy my Evo on any dry road. Body roll is becoming an issue with this level of performance. Real fun is on the twists, and I know that the Evo can excel with the right setup.

I will post time slips next Monday once I scan them.

Cheers.

Sergio.

 

congrates Sergio!

 

thanks, matey...I wish I was in Tucson with all of u guys. Tons of fun over there during the last week, huh?

PD is in the house!!

 

Great job, Serge. I thought I explained all that to you already in relation to the power output on the Mustang Dyno vs trap times and such. Remember back at the beginning where your goal was to match my times, and I knew you could do it even on pump gas if you learned how to launch. Well, you learned how to launch, and you pretty much matched my times, even though you're just on pump gas. You also matched and surpassed my best mph (113.7 in 5th, 113.2 in 4th after rev limit raise). You are now making just enough power to hit 11s, but it will take a perfect launch with perfect shifting...perhaps not likely on those crappy tires off your Mini Cooper, you crazy man.

Anyway, welcome to the world of low dyno numbers and fast track times. There's nothing better than that combo, because it's usually the opposite - high dyno numbers and crappy track times.

 

Thanxs Warr...I couldn't say it better.

By the way, I was looking at your time slips (12.01/12.07/12.18) and I noticed that your 1/8 trap speed is considerably higher than mine... I mean, we're talking 3-4 miles higher! I'm very confused since my 1.7 launches didn't bring any speed improvements.

 

Nice job buddy!

"THAT IS SO TRUE" Good times

 

I think it's the 6spd. The gears are much shorter, which allows MR owners to rap through the first 3 gears incredibly fast. This also means we hit 4th well before the 1/8th, so I have time to hit full boost in 4th and start accelerating earlier. 5spd guys are usually shifting right at the 1/8th-mile, so I think that tricks us when reading the timeslips. We never seem to pick up as much mph on the back half, because we've already used up about 7-8mph in 4th before getting to the 1/8th-mile...while 5spds pick up 25-26mph for the opposite reason. That's my theory anyway, because I'm obviously not making 3-4mph's worth more power than you. If anything, I'm making LESS power, but I'm able to get halfway down the track a little faster due to gearing...

 

I forgot that you drive a 6-speed MR. Your theory makes a lot of sense, however my best friend Carlos (fromWRXtoEVO) drives also a MR but his 1/8 trap speed is a bit slower than mine. His best is 12.48 @ 110.

 

That's because he's racing in Tuscon, not at sea level on the East Coast.

 

True. I already forgot about the pernicious effects of the altitude on cars.

BTW, as I promised, here's my time slip. The other car was a SRT4 making some serious power. I was impressed with his 111 trap speed.

 

This is incredible for 93 octane and no type of meth injection! Your tune seems to be just sick! I never heard of a stock turbo, 93 octane car that traps 114. I wonder how much your skinny tires are helping your top end?

 

I drive an MR also and also have similar traps in the 1/8th to Warrtalon but not quite as much top end (HP). Your friends 60's must be in the 1.8's or his shifting is maybe a little slower although that time is still respectable. In comparison, I ran a 12.34 @ 108mph.

Nice times and your car is making great power

 

I thought that 114 was common for my set up and level of power. However, it seems that the PD Mustang dyno located in Philly reads lower numbers than any other Mustang dynos.
About the snow tires, some of you may think I'm crazy for using them on the track, but I drove from Colorado to the East Cost to attend a 2-month course and decided to put them on the car due to bad experiences with snow in the past. Since I'll have to drive back to Colorado in mid December (1,800 miles), I thought that it was too risky to cover such a distance with the summer hi-perf Advans. And the reason why they're just 205's is because I used to have them on my late Mini Cooper S.
Anyways, I don't think these tires are helping my trap speed since they have the save circumference as the OEMs, then gearing ratios are about the same. Traction wise, they're definetely hurting my times because they're too narrow.

 

Thanks!

My friend's 60's are in the low 1.7's, and he's a hell of a good shifter. The problem is the altitude.
Top end wise, what it really makes a difference are the cams. On my car was like night and day. So far its been the best mod, hands down.
