With that MPH, some MT DRs might get you into the 10's as is (even granny shifting).

In regards to power, I have no idea. All know, is what it did on our dyno, which has been proven to read lower than a dynojet. Trap speeds can vary by a lot of things, so I wouldnt read too much into it. I am just happy with the results, especially taking it pretty easy down the track. I basically just relaxed, and didnt try to force anything. As a result...nothing broke! :THUMBUP:
Jeremy, a run from a 60mph roll would be a lot of fun.
These Greddy turbos are already pooping out. There isnt a whole lot more airflow available from them. I did 590whp at 16.5psi, and 650whp at 19.5 psi.

Again, Nice Job!
yeah , the problem is that the domestics have a straight axle and they pull 1.3 to 1.4s all day, thats good for a half a second in the quarter mile over our 1.6 to 1.8s.
we have to work on our suspensions and get it all dialed in to compare our trap speeds with any domestics...

Yeah, my car is always going to be a fully streetable circuit car, so I dont expect to do much more with it for the dragstrip, other than putting some slicks on it. It's a lot better in the corners, than off the line.

im still going to prove you wrong here soon that i cant lift the fronts off the ground....
pics soon!!
I never said you couldnt lift them...sure would look neat!
Here is a vid of my run: http://www.youtube.com/watch?v=PEXp4DPlNpI
give it a few minutes to process before clicking

Very few street cars, domestics or imports, pull 1.3 - 1.4 60 fts. at the track. Most street type cars typically pull 1.5 - 1.8 60 ft times depending on whether they're on a full bias ply type of slick or a DR. Not all domestics have a straight axle and not all imports have an IRS type suspension.

right, but most domestic (american cars like mustangs, corvettes, chevelles , novas, GNs, etc) that i run with pull better 60 foot times than us guys with IRS. its not a guess, its just the truth. our suspensions are made for cornering, not launching and getting traction with TONS of hp.
i dont just make stuff up, i am going from what i have learned and seen in my years of drag racing imports...
i know he got a ok 60 foot because he was launching with lots of power. but that same power on slicks would only yeild a 1.6 possibly a 1.5 on a lucky day where as a american straight axle car with similar hp and good tires could pull great 60s...

pics soon!!leave the oil pan crushing,bumper scraping wheel stands to the mustangs
my dream would to be to yank the wheels again on the 1-2
t-trim 331 should do the trick

Picking up nearly 30 MPH in the second half of the track is no joke!!
You are definately making power
Now you have a good starting point and something to think about before the track opens again next year.

An auto, often with a trans brake on a tire with 90/10s tends to help things too... That and probably having alot more experience at the track with their completely superior setup (far beyond just the difference between IRS and solid rear) than most guys in 350Zs.
Inexperience with launching on that particular tire and trans setup, and too much power for the tire both are much more significant with regards to Sharif's (and many, many other people on here) 60' time than the simple difference between IRS and a solid rear axle.
There is no doubt that ultimately, a solid axle that doesn't increase the negative camber is superior for launching at the drag strip. However, pointing at the IRS as the "reason" that some "domestics" cut 1.3s while basically stock suspensioned Zs with a BFG DR and boatloads of power are cutting less than stellar 60' times, is naive. A helluvalot more work goes into launching a car really hard than a swap from IRS to solid rear axle.
Sharif - Nice work. More practice and more willingness to really wail on it will definately go a long way. Keep workin at it mang.

The reason Solids are typically preferred over IRS's for fast cars is all in the strength. A built up solid rear axle will resist breakage much better than any IRS. Less torsional movement among parts means less breakage.
