time for a bit more power

[peterwolds]

standard engine except power fc and commander,hard pipes and twin induction kit - before pipes/induction mapped at 225 RWHP,dont have a boost controller.
dont want to go mad but like to see around 280 RWHP whats the best route(presume fuel pump & injectors a starter) ?

It depends on what you really want. You could decat and remove airpump to get more ponies but you will probably want to increase the size of your injectors and put a better fuel pump in as well. You may want to swap the stock intercooler for a bigger stock mount too if raising boost levels.

It will make the car much louder too so if you do alot of motorway miles you may want a silenced mid pipe.

280RWHP shouldn\'t be too hard to get, you\'ll have raise your boost level too to get to that figure.

Cheers Shaun,not worried about being a bit louder my exhaust is a dunke megaphone it makes a stealth bomber sound loud  :rollin .
due mot july have to see how emissions come out not got decat pipe on at moment,bit of faffing about when i had an evo putting cat on and off for mot but should give another 5 ponies or so if decat fitted.what size injectors is it going to need around 850 ?
had a walbro pump on my evo was loud when just ticking over whats the bosch like do you know ?

The stock injectors are 550 and 850. Usually people upgrade to 1200 on the secondarys to get a bit more flow. Pip at WGT upgraded my pump and injectors so not really sure what im running pump wise. It isn\'t any noisier that the stock one.

You may find that it can be tuned without the injectors needing to go any bigger. I think the cutoff for the stock injectors is around 0.85bar of boost. Im running 1 bar and see about 75-80% duty max on the 550/1200 on a rich map.

I\'d say fit a bigger stock mount first and get it remapped and assess what you need to do to your fueling, any of the tuners on here will tell you want is best for the car !

Jon (hotstepper) is running about 0.9bar boost on stock intercooler and stock injectors without too much headaches !

thanks again shaun - takes a bit of getting to grips with RX7 after evo especialy when talking of boost levels like this as my evo after ecutek done on ecu was  at 1.5 bar  - learning as i go along,should get a boost controller (either AVCR or Blitz ) as well as change intercooler.then looks like a trip to manchester for remap

Mine has got 280 at the wheels at the moment and all thats different from yours is its decated and been mapped well. Standard engine, intercooler and injectors, running 0.8bar

strange wonder why so diferent decat only adds 5 ponies or so,mine was mapped by reworx before i got it wonder if been an ultra cautious mapping ? Had a quote from "sam the dentist" for mapping was £400 which i thought was high for a remap job plus rolling time at scoobyclinic which was £75 last time i had a car done - did include 3 runs whilst ecu was flashed & mapped

where did you get the mapping done if you dont mind me askin

Unless you have a cold air feed for that induction kit I\'d go back to standard as induction kits sucking in hot air = less power.

I\'ve got standard engine, apexi, HKS downpipe with Re-amemiya mid pipe and catback, non seq turbos and made 285 at the wheels.

Bulla was mapped before induction kit added,no cold feed yet

Pete if you don\'t want to go new intercooler you\'ve also got the water injection route.

[shaunwil]

I\'d go for the greddy profec b spec ii for boost controller, infinately adjustable !

I\'d go to wgt for your mapping session, closest place i can think of ! Maybe the downpipe and cat bringing your figures down. If you off to manchester its only another 30 mins down road.

Re Works did my mapping for me when they fitted the PFC.

Hi Kevin
how are you doing?
Think intercooler is my prefered route dont know which is best to go for in my case spent a lot lately with new bonnet (spray costs to come yet GULP ),induction kit,hard pipes and suspension

Shaun - intend to go to wgt knew were manchester (ish) didnt make it clear above when on about "sam the dentist" mapping (great bloke knows evos and scoobies but not sure on RX 7\'s) want to use someone who knows the limits on mapping safely an RX7.
never thought about greddy boost controller thanks will take a look at specs had a blitz dual sbc in evo was simple 4 settings for boost
