Here is my current go fast mod list:

Apexi GT Front Mount intercooler
Apexi Power FC
Apexi dual intake
Apexi GT exhaust
HKS Downpipe

I have never had my car timed but I think I am probably running low 12's right now with this set up? What do you guys think? My goal is to have a reliable car that will run in the 11's. My engine has about 4000 miles since my rebuild. Turbos also brand new. Is there anything I can have done to stock turbos to put out more HP i dont want to go single and I dont want to lay down the cash for totally new turbos sinc I just dropped almost $2500.00 on these. Let me no what's up and what its gonna take.

thanks Guys

 

If that is a stock FD with those mods, no way is that an 12 second car. You maybe have 280-300RWHP. To get to the 11s need tons of mods and tuning. Need about 380RWHP. That is just breaking into the 11s.

Ken

 

yeah man, get it timed,
go to the track!

but if your pushing enough boost, you could prolly be in the 12's,

doubt low 12's though

 

300 RWHP should be around a 12.5 second 1/4 mile. You will need practice and a good 60 foot time to hit 12.5 seconds. For every 0.1 s lost in 60 foot you will lose 0.2 s in 1/4 mile. Just remember that when you actually run and get a 13.0 s 1/4 mile time!

 

get a single turbo upgrade! as well as more injectors/ bigger injectors!!!

 

It takes 360 rwhp to run 11.3's to 11.4's (Brooks old car did this on 362 rwhp...385 rwhp gets you into 10.9's to 11.1's Kevin Wyum and Anthony from T&R ........

 

I don't know about 11 sec but run an open mid-pipe and you can pick up some extra HP.

Later, Jeff

 

no way man... 380? that's DEEP into the 11's I'm pretty sure like 350 would get you there w/o much difficulty w/ a half decent driver

 

I agree with the overestimate on your time....Im probably running mid twelves and I have the streetport and am pushing 13lbs of boost...plus the n1 dual, hks downpipe, pettit intake, gforce ecu,upgraded radiator, koni yellows and H&R spings etc...without the streetport...Ill drive right past you....but that supercharged c5 around here still drives right past me....must get midpipe...must get rear gears..haha

anyhow...the midpipe..streetport...gears....etc...should get you near 12.0 Id hope...at least that is what the other boys round here have told me...Im getting the 4.30 gears and a bigger intercooler asap...I must hit 12.0...I dont know what else to do to hit 11 sumthin...but i dont want to go single turbo.

best of luck.

I hope you don't expect to gain 1/4 second in the 1/4 mile with 4.3 gears.it's not going to happen.

Ken

 

Drag slicks would help, the 0-60' times are a key

ken

 

whuts the point of getting the geas if they dont shave off any time??

will the 4.30 gears give me more low end pull?

they should right?...I ask cuz I havent ridden in a car with them installed....

Im getting the nitto 555r street drag radials...that will help too..I agree...

how much time should the midpipe..intercooler and gears shave off my time?

jason

 

im not sure where you guys are geeting your figures from but i now for sure at the most im running 12.8's .
I know acouple cars with Identical setups who are runnning low 12's. Best example would be Alfred (Apexi RX7) he has almost same setup and runs 12.4's all day with 17" racing hart C2's. Stock Rx7s run 12.9s to 13.1's with a good driver. Stock horspower was 250-255 hp so you are saying all these mods just gave me only 40-45 horsepower B.S. i respect alot of peoples knowledge in this forum but alot of you dont seem to know whats up.

ARTGUY: You say you wll walk over me without your streetport???????????????? Alls you have is exhaustand a dp. Come on man think about what your saying before you say it.

Full mod list

Apexi GT FMIC
Apexi GT Exhaust
Apexi Intake
Efini y pipe
Greddy elbow
Hks DP
Apexi Power FC ( running 13lbs)

and im probably forgetting something

 

hey 1QK7

ya dont believe me....Ill drive down to san D next weekend and show you.

there isnt a car out there with the mods you have that will take an identicle car with a streetport. It just doenst happen...even if you are pushing 15 pounds of boost and mess with your pfc.

sorry dude.

but I say this with a smile...maybe your car is really fast

The only time I ever lost to an rx with your bolt ons was when I missed my shift from 2nd to 3rd while passing him and blew a synchro in fifth. I smoked him the first time.

that put an end to my racing for the weekend.

my car will be on the road on monday...let me know when you want to go.

you may take me off the line...but once I get into second..Ill be beside you...and once I get into third you will see my ***. :

haha

Im just playing with ya...

but seriously...Ill meet up with you next weekend if ya want to find out the truth.

j
94 modded PEG

I do know there are a lot of rxs out there who will smoke me like a cheap cigarette....but not with the basic bolt ons...and not with a body kit and a paint job either

 

by the way...255 hp for a stock rx is at the FLYWHEEL...not rwhp.

you said you didnt respect some of the people on this forum (in so many words) for not thinking before speaking....these guys are very helpful...my car would not be in as good condition if these boys werent here to answer my often dumb questions.

meet me at the races next weekend and the truth will be told.

j

 

Actually a stock RX will just run in the high 13's and that's with the best of drivers...

 

That's true of FDs, and they are 255bhp stock. That about 215RWHP on a 5-speed.

ken

 

To answer the original question, " what it would take to get him in the 11's", wouldn't he have to just turn up his boost a little to 15lbs or so?? that is if he's not already running that much... And maybe he can add some underdrive pulleys and delete the air pump and maybe that'll give him some extra horses....

 

To run 15 lbs, he's going to need to upgrade his fuel system...

 

hey

15lbs of boost wont get him to the 11s...

not without a streetport or a midpipe and gears....at the very least.

this is what the boys round here have been telling me as well.

yah...13.1 isnt happening on a stock rx...maybe 13.6 in a brand new one back in 95...and that would have to be a lucky day.

j

 

ARTGUY- Im not trying to step on anyones toes I just don't think you no your *** from a rx7. You say you are runnning 13lbs of boost with a downpipe,intake,street port, g force ECU with 13lbs of boost? Lets do the math
Dp 10-15 hp
intake maybe 10 hp
N1 exhaust maybe 5-10
Street port 20-40
G force ecu= 0

You said 13 lbs of boost? Im not sure how considering you have a downpipe,n1 exhaust and intake without any form of boost control??? You proabably think you car is so fast because your really having boost spikes from 10- 18lbs of boost. G-force does not control boost it only re-maps the fuel cut so you can deliver fuel up to 13lbs?? So how are you controlling the boost spikes im sure all of us would like to no so you can do it for me consistant 13lbs without a boost controller is a litlle hard to swallow for me. Come on Mr Rx7 you should no that.

So we are talking maybe 310 hp at the flywheel

Now lets do my car

APEXI GT FMIC 20-30 hp
apexi Dual intake 5-10 hp
Hks DP 10-15
Apexi GT exhaust 15-20 hp
Apexi Power FC running 13lbs of boost 20 -40

Lets do the math

360 hp to the fly wheel for me

oh ya you will walk all over me

i would love for you to come to San Diego not to run your *** just to see another 7. There is a huge Auto Cross dwon here i think next saturday it would be cool to have more sevens down there. Oh ya one more thing I took these directly

From Pettits web page and Rays website it is there packages and what HP they produce there are dyno results on their web pages to back up there results

The Pettit Racing Turn Key Terror
Think of the Pettit TKT as a complete Stage 1 high-performance package upgrade to your 3rd generation RX-7. 320 Hp gets this bad boy to 60 in 4.4 seconds and the extra handling hardware generates 1.05 lateral g!
The additional hardware:

TKT Cold Air Induction System
TKT Power Pulley Kit
TKT Cat-back Exhaust (dual tip or single 4" tip)
TKT Front Sway Bar
Trak-Pro Eibach Springs

Thats 320 hp from a car without only part of my mods????

Sr motorsports
Package #4
SR downpipe, SR stainless steel catback, SR medium intercooler, A'PEXi Power FC, SR power pulley and Nipondenso HP fuel pump.
320HP
$2980
Savings of $364.00

Like I said before please think before you speak. If you think these numbers are fake then please call Cam at pettit or Ray at SR motorsports and tell them how full of **** they are. Maybe there Dyno was messed up that day?? and don't forget to tell the you have STREET PORT and you can walk all over them.

Sorry for the long post

 

Good lord that was one long bench racing and ricer math post.

OK, dood ... I hate drag racing and using RX-7s for drag racing, but I'll tell you what you need to do. Rotaries need fuel, and proper fuel tuning is the difference between an awesome rotary and a dumpy rotary. You need a bigger fuel pump (Cosmo? GT-R?), larger injectors or an extra fuel rail (either get a GReddy injector elbow or get someone to cut them into the upper intake manifold) ... and I don't know much about the Power FC, but if it doesn't control extra injectors and you go that route you'll need a Rebic. You'll also need to have the Power FC properly tuned. Turn up the boost to ~18psi and go for it.

And get the midpipe everyone else was talking about.

 

Once again sorry for the long post but I just had to do it. I agree im not that into drag racing I like auto cross much more but when I do Drag race i want to put it down.

 

I agree that it will be good to see the other sevens in the area...me and some of the boys get together on the weekends...Ill ask them to come along...all in all there should be 4-8 of us. I know two other sevens down there and three more boys up here with nice ones...will bring them too.

my streetport hp gain was 35-40...rotary reliability did it and Nick has been porting rotary motors for 20 years...he knows what he is doing...trust me. my boost is controlled manually.

I will come down to san d on saturday night...if you want to meet up let me know...email me if you can back up those words of yours with a car that outperforms mine.

CAN YOU EXPLAIN HOW THIS PETTIT CAR WITH LESS MODS THAN MINE IS PULLING 320 HP WHEN ACCORDING TO YOUR SHODDY MATH MINE IS AT 310?

come on guy...do some thinking for yourself..instead of belittling others. In the future..if you read some numbers off a commercial website..at least compare them to your own calculations.


here are your numbers....well pettits numbers...

you said...."Thats 320 hp from a car with only part of my mods????"

well "mr math"...that is only part of my mods too! but even with those numbers...since when did a pully set and an intake and 3 inch exhaust equal 65-70 hp??? that is the difference between stock and the 320 that pettit claims. If I go by your numbers...10-15 for the intake and 15-20 for three inch exhaust then that means that the pully set has to add on additional 30-45 hp.

If you can order me a pully set that will give me 45 hp then Ill pay you cash money today!

bring it on.

follow your advice and think before you speak. I did some thinking and yours... well....again it didnt add up!

 

i too don't believe pettit's numbers add up. maybe someone could e-mail them or call them and ask how they came up with 320 hp.

well here's a question,
if you have k&n air filters, a downpipe, midpipe, and stock catback exhaust, how will the fuel system fair? will the stock computer it be able to handle or will i need to go get a power fc? caould you control the boost with something cheeper?

(i'm only asking about the midpipe because i think it's time my cat is replaced, and a new one cost a bunch more than a midpipe. also, how do you guys think this will sound? stock cat-back?)

help,
