right now i have downpipe, highflow cat and catback. my next mods are midpipe and intake. then what should i do from there to get the most hp for the least amount of $$? unorthodox pulley set? ball bearing twin turbos? flywheel? how much hp could i realistically get without going single and without spending a fortune, i know that''s inevitable. can somebody give me the list of what you would do in order and how much hp each mod would give. thanks for your input, i lost sleep last night because i almost lost a highway race to a stock slowmaro z28.

JoeD

no they are not. your next mod is an ECU.

jaydogg

i knew i left something out, i have an m2 stage 3 ecu upgrade but i know with prety much any more mods i'll have to get a power fc.

7sweetie

dont get a pfc, they are ****, unless you have the means to get it specially mapped. which is a pain in the ***. i would go with haltech personally, its a lot more user friendly. about hp without going single, what is your hp right now, do you know? from that i could probably give you an estimate.

JoeD

not the install. and you gotta have a laptop.

RotaryKnight

Why is a haltech easier than a PFC....both have to be remapped for mods and PFC is atleast plug and play for the mods he will have. It's a 5 min install for the PFC.

BTW the weekend of the 18th in AZ placing bets that there will be a new street class king...and yes it does use a PFC.

RecKleSs

Since when has the PFC been a POS? The PFC has been proven that it is a great ECU for a really long time. As for the Haltech, have fun spending $2000 on the unit and that unit is definitely a pain in the *** to install.

I'm going to wait for the AEM EMS.

Well, without going Single, you could probably get around 350rwhp out of the car before trashing it. However, it won't be cheap, but cheaper than going Single Turbo.

Most FD owners with stock twin turbos end up around 300-320rwhp which is plenty.

What ET's are you looking at with 300-320rwhp?

kwikrx7

From what I've seen FDs with around 330 rwhp are good for 12.0-12.1 with 340-350 rwhp good for 11s. The PFC needs to be tuned correctly and they are finally getting the bugs tuned out of them (timing maps) I would wait on the AEM - they are untested and will probably have some bugs to work out for a while - in about a year they will be the "new" thing to have. It's tough to get 350 rwhp out of a stock motor but I've seen it done with a Haltech (more tunable) - If you have acess to software for the PFC which hardly anybody does you can get nice numbers out of it. With a ported motor and 15 psi on stock turbos with pump gas 380 rwhp is possible but is pushing it. Most "BPU" FDs are running around 280-320 rwhp.

My RX7 (which I'm selling) right now puts down 350rwhp/300rwtq @ 1.05 bar. This is with stock twins running non-sequential. I have never run the car at the track, but I have raced a many 12 second cars. High, middle and low. While I get walked by the low 12s guys, I can hang with the mid 12s guys, and walk the high 12s guys. With 350rwhp I think you're basically looking at mid-high 12s easily. I think it would possible for someone with a street port and high boost to take a stock twins into the high 11s. Low 12s for sure. Just my 2 cents.

Would that by any chance be XSPOWER?(I mean the blue XS FD, I think that's his forum name?) ?? That car makes gobs of power..

RotaryKnight

Actually it is not XSPOWER's car but i am talking about the blue FD from XS. Pete (not XSPOWER) has done a few changes to the car. The last meeting agianst Ari he misshifted 3rd in the final run. The car was put together last minute with suspension changes and didn't even have alignment done..he's put in the HKS Hiper Drag suspension the night before.

I was down at XS friday and there are even more goodies being put on the car. This will be a good match up. Pete is pretty serious about taking the street class title.

Ivan put down 387rwhp on stock sequential twins, he had a street port and was running 17psi, but on 13 psi he made 358rwhp

With those mods you should have beaten that camaro by a long shot. Back when I had just my downpipe, ecu, and cb exhaust I was already spanking modded Z28's easily, check to see if you're boosting right or if anything else is wrong with your car, you should have blown that thing away

ttpowerd

you are going to probably need intake, pulleys, midpipe, aftermarket ic, fuel pump, injectors, clutch, flywheel, and street port.

Are you going to be there by chance?
