How to tell if your engine is modified?

We've been having conversations about my car. It's a freak of nature!

The car was stock when I bought it, except for lowering springs and a front lip. Since then I have only added an AEM CAI. But this car is a monster for some reason.

If any of you have seen my track results...they're pretty good...14.80 with only an intake on street tires...and the thing is I'm smoking the times of Heavily modifed (full bolt-ons only like I/H/E, VAFC, Pullies, Cam Gears) 5th gen preludes here.

So what the hell is going on here? And don't say weight cause the 4th gen and 5th are only 22lbs apart.

I am dyno tuning for my new V-AFC next month so I will know what I'm putting down...but is there any easy way to discover if anything internally has been done? I guessing no, but I had to ask cause this is driving others nuts haha...

what elevation are you running at? and weight is not the only reason that 5th gens are slower.. the gearing was different...
and well i'm assuming you think your car was modified internally.. unlikely since your times arent that far off what a stock 4th gen runs.. nice runs though really! .. wait till you get your other boltons should be great..

True...we're running fairly close to sea level I would think...Southwestern Ontario is surrounded by the Great Lakes...

I really don't think it's modified internally...but my 5th gen friends are looking for excuses as to why I'm kicking their asses...

There are such things as factory mutants, once in a while you get lucky!! I had a stock Yamaha R1 that would lay waste to a modded one, it was just silly fast from the factory.

Not every car from the factory is the same, you most likely got a really good one!!

SR-V = VTEC

And it's a 96 OBDII so isn't the timing automatically adjusted by the ECU?

I went head to head a couple times with a 1g Talon TSi AWD at the track...he'd get me off the 60 with the AWD but I'd catch him at the end...my R/Ts were better though

Ever think that since you live in canada that the exhaust requirements just aren't as heavy as they are in the US. They probably didn't tone it down like they did for the states. Just a thought but I don't know for sure.

Peace

I'm pretty sure they're exactly the same as the US, except for restricted states like California...but I'm comparing my performance to other Canadian cars too right?

Your sound doesn't sound too far off. I'm sure there's other people out there running high 14s with just either an intake or exhaust alone (me not being one of them because I suck). But your timing shouldn't matter because of your OBDII like you said...

Its finally nice to see a good review of the supossedly inferior OBD-II system. I also have a 96 SR-V, and it goes like stink. Before I bought it I tested a few 95s and they didn't seem as torquey. Yes I know its not a fair comparison comparing used cars, but I did feel a difference.

I've heard a lot about how the OBD-II doesn't respond as well to mods but I've never seen dyno results to back that claim up.
Besides I also heard that the OBD-II system didn't work properly on 96 models.

As for the claim that a few cars are built "slow" well there is a BIT of truth to that. As you may/may not know, there is tolerances for every component built... so for example if your cylinder diameter is on the high side and your piston/rings on the low side you could have a looser fit, compared to a car built with the reverse situation. BUT, the engineers design w/ this tolerance in mind to take out most of the variation.
