So you're saying that you are only half a car behind to a car that can do the 1/4 mile in 13.9 seconds stock?

Dude, it's still BS. Stock SRTs are putting down to the wheels almost 100 horsepower more than you are with a 5 speed in a car that weighs much less. That's a lot more than 1 car's length.

I agree. Stock J's only come w/around 210 HP, plus they weigh 3,500+ lbs. Post some videos of you racing, then we'll see where you stand.

So if you can lose to a SRT-4 by only a car & a half, that means that I shouldn't have beaten a J30 by 3 lengths on a track w/my stock Honda Civic LX, huh?

BTW, I have a 5-speed auto tranny

Go to my CarDomain page to see the videos & do a search on YouTube to find the MotorWeek specs on the J30.

210 hp on the J relates to about 160 - 170ish at the wheels. MANY people have dyno tested STOCK SRTs and shown them to have around 240 - 250 hp TO THE WHEELS even tho manufacture's specs show only 230 hp at the engine. They were WAY underrated.

3 full seconds faster down the 1/4 mile is an eternity. MUCH, MUCH more than 1 car lenth.

(Plus, you can EASILY get a SRT over the 300hp mark with a little money.)

I think Dodge underrated the SRT-4s for insurance purposes.

Seriously, different manufacturers give different HP numbers from different locations. I've done some thorough research, & I found that Honda gives their numbers for horsepower to the wheels. I thought Infiniti did the same but I guess I was wrong.

Also, it depends on the mileage & condition of the car as to how accurate your HP readings are. & torque plays a huge part in this as well. J30s come with 192 lb-ft of torque from the crank, right?

Honda's rating are at the crank not at the wheel.

Ok, I did some research on that this weekend while at my aunt's. Unfortunately (for me), you are right. So that means I'm kicking out around 110-120 to my front wheels.

Rapman, post some pics & vids of your J30!!!!!!

I'm guessing by TSi, he meant TSi. As in, and Eagle Talon TSi.If he meant STi, then someone snuck a TT engine in his car without him knowing it.

If he's keeping up with an Eagle Talon TSi, then they don't know how to drive the TSi. Those things can fly.

I think they come turbo'd from the factory.

SRT-4 is in the Doge Neon Right?

If so: http://q45.org/josh-vs-bumblebee.wmv

I know that the J30 has no VH but you can put one in a show them what a J45 ca really do. Plus your cars are lighter too.

Sorry but a 10.26 is about a 16 second 1/4 mile. That had to be the WORST driver (SRT) that I've ever seen. He spun off the line (with terrible reaction time too) then bogged into second then shifted WAY before redline into third. Was that even a SRT or just a N/A Neon with no muffler?

I've seen lightly modded SRTs run 13.0 second quarters in person (about 8.3 in the eighth) and the car magazines (Automobile, Car & Driver, etc) got high 13s (13.9) out of them completely stock AND in full street trim. (No weight reduction, tires at full PSI)

A 3,500 lbs car is going to have to have OVER 300 hp (crank) to break into the 13s (13.99) in the quarter and I don't think a VH powered J45 will have that much?

maybe not a stock VH...ive been in touch with thomas knight...he designed a supercharger for early 90s Q45s...when i do the swap i plan on boosting it for sure...from his specs its an additional 110 whp however itll cost roughly $6K for the entire kit...

but in the end after all is said and done who else will be able to say they haev a supercharged v8 J?

Do you have any more info on that super charger because from what I hear, Since Wes or someone else blew his/Their motor up the project has ceased.

The Neon/SRT-4 had a 0.19 reaction time to the Q45's 0.6 something. That was just sheer power on the Q45 & bad driving on the Neon's part. Unless I missed a detail...

10.2 (16.0 quarter mile) doesn't qualify as sheer power in my book and the fact that I think we are missing is I don't think that's a SRT. Even with a CRAPPY driver, an SRT would have pulled pretty good on the Q.
