What are average 1/4 mile times for bpu 3rd gens?
 

My friend Billy just paid a performance shop a rediculously high amount of money to install BPU mods on his car. It's a 94 RX7 with a veilside kit, aftermarket wheels, intake, exhaust, Bov, etc. I think he also had larger injectors and a boost controller installed. Anyway, after it was all said and done the shop (some place in Texas) dyno tuned it for him. It peaked at 301rwhp. This seems like a relatively low number considering the price that he paid for his mods. However, If you take the weight of his car into consideration, it should be pretty dammn fast. Which brings me to my question. What are some average 1/4 mile ET's and traps speeds for RX7's with similar mods?

look around a little. times are posted all over the place.

a veilside kit adds no HP. neither does his BOV.
what is using to control these larger injectors? what part of the exhaust? the entire thing? just a cat back? with the boost controler...what boost is he running? if it is at stock levels? then that also adds no power. if he is running more, he is going to need an ecu or maybe a motor soon...

It depends on how you define BPU since thats mostly a Supra term for full exhaust and more boost. Since the RX-7 has so many factory deliquencies unlike the Supra, I wouldn't consider it to be "BPU" without an intercooler, full exhaust, fuel pump, and a computer (more boost goes here). If that's the case, a propely running one should get 340-350 rwhp and run low to high 12s @ 110-117 mph depending on tires and the track.

i hate that word BPU.. sounds silly. its even trademarked now.. like who else uses the word besides supra groupies?

Damn STRAIGHT!! :bigthumb:

O.k. Thank you to those of you who answered my question but as for the rest of you WTF? This was my first post on this board, I was just trying to ask an honest question. I was hoping for an honest answer, but instead some of you just replied to my questions with a few smart ass retorts. Thanks alot. Are you guys always this courteous to new members?
No sh_t. Thank you captain obvious. Please don't assume that since I don't drive an RX7 that Im a complete invalid.
Im not a supra groupie, you jackass, and I dont appreciate you saying so. Almost every automotive board that dicusses vehicle modification will occasionally use the term BPU=Basic Power Upgrades=exhaust, intake, boost controller. Im sorry, I didn't realize that it was a cardinal sin to use that term.

I think I should just start over again from the beginning, since apparently you guys think im bashing my friends RX7(why else would you be such smartasses?). Im not bashing his car. I think RX7's are awesome, along with the 300Z, Supra, VR4, C5 vette NSX etc... I was just curious how fast his car really is. I would like to know before I race him this weekend. Billy's car has an upgraded fuel pump and injectors controlled by an SAFC. He has also had a downpipe and a stainless catback exhaust installed as well as an electronic boost controller and an upgraded intercooler and blow off valve. It was dyno tuned by a performance shop in texas. He told me that it dynoed at 301rwhp, but that may have been on a low boost setting to prevent knock. I can personally run an extra 2-3 lbs of boost on my car if I'm using race gas to prevent predetonation. According to what I've read on here so far, If he is running race gas he should be in the mid 12's or lower if he doesn't biff the launch. Does that sound about right?

i'd guess mid-high 12s

Calm down there a little. When you think about it this is the performance section, not the exterior section. You didn't have to state your buddy had a veilside kit.

But I agree, good skills should get him high 12's.

What specific brands were put in his car?

And out of curiousity, how much??

No, but getting flamed with your very first post really is a retty impressive way to make an entrance. :D

and talking shit back to a moderator with your second post is even more ballzy. ;)

BPU isn't something that is the same on a Supra vs. FD.

I'd consider a FD BPU'd if it had 2-3 mods. Like intake, DP and cat-back. The reason I say this is because adding more boost isn't really advisable with the stock ECU or intercooler. People do it, but IMHO they shouldn't. Intake temps get hot with the stock IC and a/f ratios get lean with the stock ECU. Lean and hot isn't good. IC and ECU upgrades imply spending some big $$.

Sooo... considering the above BPU statement I'd say mid-13s.

Your friends car should be able to do high 12's with 301rwhp. Stock cars put down 215-225rwhp and run 13.9-14.2. Adding ~80 rwhp should really make the car pretty fast.

Welcome to the forum!

Later,

:rofl:

anyway....i was saying there was no need to list a body kit as a MOD when trying to determine if you are going to loose a race to him.
btw, why dont you just race him to find out? i dont get it. and how would i know you dont own an rx7? did you mention that anytime before my reply? or was i supposed to figure that out by the use of the term BPU?

if you are a much better driver than him and his car had 400HP, you could still beat him and i dont even know what kind of car you have. there are to many factors to consider to *tell* you if you will "win".
btw, the safc is NOT the way to go on an FD unless he wants to constantly change settings.

what is the point of this thread?
Q:did you want to find out what his times would be? A:then how about taking to the track?

Q:is it to find out from what we tell you his times should be to determine if you will *beat* him in a race?
A: a. take the two cars to the track and compare time slips
b. race him and find out.

Is "Billy" on the forum? He should be. All FD owners should be.

I guess I should have clarified my point. I was simply trying to give an overall explanation of Billy's car, rather than simply list his mods. Either way, I guess there's no point in arguing about it. Thanks for the information. As for the point of this thread, I just wanted to know, based on previous times, weather or not it would be a close race if I were to accept his challenge. I would rather not race someone if the odds are stacked undeniably against me. From what I've read so far It should be close. For those of you who were curious, I drive a black 97 VR4. So far I've added a full 3" turbo to tip exhaust, intrax lowering springs, 450cc injectors, an SAFC, a 3sx underdrive pulley, a supra fuel pump, a K&N FIPK, a short throw shifter, and a Blitz Dual solenoid boost controller @ 16lbs of boost pressure. Most guys with my mods tend to run somewhere between 12.5 and 12.9 at my elevation. I'll let you know how it turns out.

Hey, welcome to the forum. Sorry everyone isn't so hospitable. (wasn't there a post about "whats happened to the 3rd gen forum...?) But hey, slamming someone for asking a simple question is cool, right. And giving too much information (i.e. body kit info) is much better than saying, "hey, my buddy's car is lightly modded, can i beat it?" You all know you would have jumped all over the poor son of a bitch who said that, so you should thank him for giving you information about the car.

Why can't people just answer a simple question, you wrote it later, it wasn't difficult. In fact, you said it in less words than it took you to complain about the fact that he gave you too much info. He was looking for a general rule of thumb about how fast FD's with intake, exhaust, etc. are. That's not too tough to answer people, c'mon now, really. A simple "12's" would have done very nicely. But hey, congrats for being conceited assholes.

Doesn't really work but is funny

WTF

modrx7, i assume that was directed at me??
If it was, this is my response, if it wasn't please ignore this.

I was using sarcasm to make a point that answering a simple question has become too difficult for conceited FD owners who would rather, it seems, spend their time making fun of someone for their ignorance than answering a simple question. Excuse the ignorant (me included) but remember, we have all been ignorant at one time, so please be considerate, thats what this forum is here for. It isn't here so you can spout on and on about how much you know about rotary engines, and in fact you know so much that it is below you to even answer a simple question. Like it would demoralize your character to say, hey Icarusfalling, it should run high 12's. The forum is here for people who need help, you should be happy to provide it based on your extensive knowledge of rotary engines and FD's in general.

Your buddies RX7 should run mid-high 12s like other stated. I know 340 rwhp is good for 12.1 and 360 rwhp is good for mid-high 11s on drags or ET streets. Somebody with 387 rwhp pulled an 11.1 at 121 mph. With the weight of RX7s you don't need a lot of power to push them. A decently modded FD with full exhaust will only weigh 2650-2750 lbs. 97 VR-4 - sweet ride:D - with your mods it should be close unless you're doing a highway run (60-130 mph)..something like that..then he'll pull you but I'm sure you could put about 2 lengths on him out of the hole depending on his driving - go race and tell us the results....
