well im in the final stages of finishing my project . and just looking at some reachable goals with power and torque

forged 347
eagle rods
diamond pistons
machined and balacend crank
tsp 2.5 and ms4
fast 90/90
ewp
arp everything
25% pulley
longtubes with electric cut outs

and just about every other bolt on ..
for nitrous .. nitro daves plate X2 other dry stages and there nano nitrous set up ... ill start with 10 then work my way up to the 300 shot..

looking for about 450rwhp on motor and not really sure on the jug ..
oviously it should be about 750 ... 450+300=750 ... but im looking for people with similar set ups ..

whats a good number to aim for .. what about torque ?

i just need a lil motivation and a few numbers trown out there to get me off my *** and just finish this thing .. still have a few wiring bugs as well *** a couple fuel things to complete ..

doing the rear end at the moment ..

so let me knw what u guys have seen made with similar set ups .. the highest number as well as the lowest .. thanks !

oh and here a few pics of my lil project !

 

Very close motor setup of mine did 468rwhp/432rwtq (after 500mile breakin) and 612rwhp on a TNT 150hp shot with 92oct pump gas, stock water pump, and 11.5:1 comp.

 

470rwhp would be great !!

that reall good u almost gainded the full 150 whp with the 150 shot riight ? how much torque she make ?

well i knw my compresion is up there had the heads milled and block decked and have a thiner cometic gasket ..and ill be running a 116oct when on the bottle ..

anyone else ?

 

Torque was in the 560's range. I had alot of issues with that motor though. Mainly consuming alot of oil, but it had gone through a couple of the first round sets of stage 2.5 heads from TSP on it.

 

anyone else ?? anyone ?

 

are you running an m6 ? your numbers will vary quite a bit from other setups. using a progressive will keep your rwtq numbers down quite a bit compared to a huge hit in the lower rpm range and i'd say you will be pulling quite a bit of timing and with a pretty safe tune through an m6 i'd say you will probably pick up around 225-250 rwhp just guessing.

 

I think your goals are realistic and plan of attack thought out well. Just one area I noticed was the fact that your pulling fuel off the rail. I would not go that route at your level without dual intank pumps or good pump and BAP, and regulator and return at the rails. Or you could run a parallel fuel system or a stand alone tank. A couple fuel system write-ups in my personal web site for insight. Get your tune inline and on safe side and you should be fine going for the levels you seek, just start smallish and work your way up logging all parameters. good luck.

With an intank 255 pump and an MSD 30Amp Boost-a-pump 612rwhp was no problem (maintained 58psi) on the factory lines and crossover Robert. Granted it wa s a single observation, but the principle is still there.

 

Agreed. We can make our stock fuel system support 700hp if the proper mods are taken. Been @ 650rwhp dyn'ed with my stock '97 style fuel system and a Racetronics single pump nad home made hot wire. However, the limits are being seen and thus my addition of a parallel fuel system to be activated only on spray at 3500rpm.

yeah i still need to do a mojor fuel over haul .. i run full stainless lines and a large pump as well as injectors .. im still considering doing a standalone fuel system but dnt knw were i can find on the fit the rx7 body .. maybe get a custom one fabed up .. dnt knw yet ..

 

Why not use your existing tanK? that's the idea behind a parallel fuel system.
robert

 

what do u mean use the existing tank ? i would like to rn 91 oct and then 116 in a differnt tank to use while on the bottle ..

after thinking it over i will probably also use a water/meth injection kit .. just for the extra safety

 

Robert just meant another outlet or sump your stock tank to support two fuel systems. But if your running pump gas and 116 it won't work.

 

This is exactly one of the reasons i don't like to run the standalone, why on earth would we want to run a watered down mix on our big shots, really makes no sense to me. in my write up i show an easy way to run FULL race gas at the track in your existing tank and then run your weaker pump gas on the drive home and save the valuable race gas for next trip. then you won't need the water/meth injection by running the full monty.
Robert

 

can u give me a link ?

thinking about it the very few time ima drive it will be to race .. so maybe full race gas in it is not a bad idea ..

Nice looking set up. I love seeing the conversions.

Since you are just now planing the stages of the fuel system now is a good time to have a accurate plan and do it right the first time. I personally love using a dedicated to feed a wet system. The availability to run C16 in the dedicated and pump gass in the tank has always worked well for me on my personal cars and customers.

However since you are running two stages of dry as well You are going to have to put mor ethan the normal on the cars fuel system and injectors as well. With that being said you could plan ahead and go ahead and build that fuel system for enough to handle everything.

The dual intake walboro pumps work well. Actually on a street car that is going to get alot of driving that is the route I would suggest. Other choices would be the aeromotove route.

If I can be of any assistance just let me know.

i already have a walbro in it now .

what i will most likely run is an aromotive pump and a sumped modified rear tank single larger feed fuel line since the stock rx7 uses a return system .. aftermarket fuel pressure reg and injectors big enough to handle the full power while on the bottle .

whats a good size of injector for my set up ..

im debating a bit ... the next motor going in the car will be a 400+ cube large frame turbo + alooot of boost .. so i might wanna make my fuel system a lil overkill for the moment .
