Just a question for all the HRC kit owners out there.

Are the HP numbers and 1/4 Mile times they post true for you guys? If not, how much do they vary?

I remember seeing some signatures from people with Stage III+ kits but they're times were not even close to what Hahn advertises.

i think that most people have numbers slightly lower than what HRC lists, i mean, they're in the buisness to make money like everyone else. they have to twist stuff a little to motovate people to buy their stuff a little more, but who cares. overall it's a nice kit (other than the little pains here and there *cartech*) and i'm glad that i bought it.

Times are acheived by having a good state of tune and by good driving. The times HRC claims are very possible if you work on it, but not necessarily the product of slapping it on and just heading down to the track. It never works like that. Experience is more important than the parts.

The times that HRC posts for their staged kits are accurate when you've got Bill Hahn Jr. behind the wheel and you're running on slicks. This is partially noted on the HRC page where they list the times.

I think HRC's advertised times are correct. The difference in 1/4 times is affected by various driving skills, and the fact that most people "customized" the original HRC setups. The difference in driving skill could really be seen when I race someone on the freeway--it's all hp then! For instance, I raced an 1991 AWD Talon that ran a 12.94, and I could pull about two car lengths on it at the top of 4th and 5th gear.

I believe HRC pulls out a 1.8-1.9 60 ft to achieve their advertised e/t's. If you've noticed, most of us that have low 60 ft times have similar e/t's to HRC's--with similar mods. Also, HRC's advertised hp is horsepower at thr crank, not whp.

I wouldn't exactly say "You are getting you moneys worth" but your are "getting what you pay for". I say this only on the money factor to justify spending $3000+. However the HRC kit is solid and the look on your face and that of others when they know...is priceless.

But the numbers are like those of car magazines; the average guy with his driving skills and tuning will probably not achieve it on his own. One of those perfect conditions under perfect circumstances things...

weasle745: and then to top it off, im not even an attractive guy. I look like Millhouse from the Simpsons, cant put on weight if my life depended on it, etc

After 60+ trips down the 1/4 this year, I would have to say if I drove the car like Bill, and had slicks like Bill, I could run mid-low 12's like Bill. It's all about tuning and driving. Mostly driving. I went faster on 8.8:1 compression than I did with 9.5:1 compression because of driving.

Take my fastest run: 13.2 and look at my 60': 2.267. Now if I can cut a 1.8 light (entirely possible on slicks with an excellent driver and a lsd), that's a difference of .4. It's generally accepted that for each 1/10 you take off of your 60', you will pick up 2/10 at the other end of the track. So with a 1.8 60' my 13.2 becomes a 12.4.

There is a guy in the Cleveland DSM club that has a GST Spyder that has an almost identical trap speed as me. His et is a 12.6. Why? He has slicks and is a better driver than me.

See how easy it is???

Stage 2 at 8psi I ran a 14.3@97 mph....not too bad huh? On street tires too.

Anything more than 10psi, and slicks are needed to achieve the "ideal" time. For example, me. I was running 11-12psi on 17" drag radials, and could NOT hook up. I ran a best of 13.5, but that run I powershifted into fourth gear and my car stuttered out for a sec which killed my top-end. My best "clean" pass was my 13.66 run. But unfortunately, didn't get off the line as well as I did on my 13.5 run. With a LSD differential and a few more pounds of boost, next year I will be striving for a 12sec timeslip with 17" street tires. Bottom line, a lot more people would have much better times if we ran slicks. We just can't hook up, a known problem with high hp FWD cars. If it was as simple as just buying a set of slicks and throwing them on, a lot more people(including myself) would be running much better times. But you need a well prepared drivetrain to do so safely(LSD, axles, clutch)......which costs quite a bit of $$$$$

Back in the day Guy did run a 13.7@103 on a stage II setup. My best was a 14.5@97 with a 2.4 60' on Stage II and I think 9psi. I hate florida tracks (moroso).

Don't forget where HRC is located. The climate up there favors better times especially in the fall and winter months. Unlike myself here in FLA where it's balls hot even now in NOvember!
