when is the borderline to upgrade to the race manifold dezod? +300whp?

 
Rep Power: 244

+1 im going to go with these rods and wiseco pistons with pnp head for 15lbs of boost ... expecting 270~300 whp andyman i never gave up on the d17 =)

I recommend it over 250-300whp for sure.

so if im going for 15lbs 270-300 ... am i reliable using the manifold it came with .. my tuner and others say it will crack but i think their stupid lol dezod ftmfw

I'd recommend the EL manifold for that power. One customer on here made 270whp on the log, and back pressure on it coupled with the exhaust he was running was causing power to fall off.

im going 3" straight through .. im not so worried about back pressure, im worried about the manifold not cracking .. my budget isn't there for a new manifold .. could i always tune and change it later? or do i have to change it and then tune?

nice rods, i think it should be pretty sufficient for any 7th gener


now i wanted to ask you Paul, i have that same manifold right now and was hoping to produce in the range of 300-350 whp, you said power was falling off in a certain engine speed due to a bad exhaust setup, now...

if i were to run a 3inch strieght pipe like EMJAY stated would i be able to produce the kind of power i want???

also, are there a spooling diffrence between the log and EL mani??

thank you

Even with a 3", the first 2 exhaust restrictions you will meet will the turbine wheel and the exhaust manifold before you meet the exhaust restriction.

See the post above, and spool properties will vary greatly from the log to the el manifold. Logs always pressurize quicker and spool faster than a tubular, but high revving and boosting is where the log will choke and the tubular will shine.

what do u mean the first restriction will be the turbine wheel? im not sure what u mean by this .. and by exhaust manifold, u mean the log mani rite?

 
Rep Power: 0

The A/R of the turbo you have and the turbo manifold will be the first exhaust restrictions in any turbocharged vehicle. So in other words, you manifold design and turbine selection will dictate the restrictions more than the exhaust diameter. And even before those will be the camshaft and head design.

=( ... so the kit i have isn't ready for 300 whp .. that sucks ... Im doing a pnp job on the head, k1 rods, weisco pistons, kpro and jus wanted to tune 12-15 lbs ~300whp .. *** how much will it restrict me ... i won't be mad if i was suppsoed to make 330 and i made 290 ...290 is still really good !! and im more then happy with that ... will the manifold hold 12-15 lbs of boost ~300whp besides its restriction tho .. i mean later on i can upgrade the turbo, and manifold if i decide to go bigger .. but as of now im looking for a semi built , semi reliable d17 .. andyman, foos ran their bitch at 250 stock, i wanna build and go 250-300 jus for reliability purposes and a lil more fun, mainly fun fun fun, im not so concerned about making th emost power i can.. its running reliable at that power level.. if it restricts me to making 260 when i coulda made 290, then im not gona be upset, cuz thats the setup i have, and its fine with me..also didn't dopes make 270 or sumthing like that on the kit i have? im not even sure what he tuned with, what happened with his setup, was it reliable, he jus parted and sold everything after doing it big

I think also your injector size and if you have a return fuel line or not will also matter... someone correct me if i'm wrong...

 
Rep Power: 244

ur not wrong .. i have 550cc srt-4 injectors, i should be good for fuel .. but paul please comment on my previous post

I think your exhaust manifold will be good to over 250, personally. I hit 247 with a log manifold. I think you would benefit greatly from a cam. My head is still a completely stock casting with no machine work whatsoever. But Paul is right, you're first restriction is going to be the turbo's ability to spool and make power in the top end on higher boost. Optimally you want everything as efficient as possible. I think if you have a dezod stg 1 kit with stock head, stg 3 cam, 2.5" MANDREL exhaust, you should be able to hit around 275-300 with dezod's turbo, assuming you have a decent intake manifold and kpro. Only one way you'll find out for sure.

As for fuel, if you're looking to get over 250, I strongly suggest a return system with an fpr. I wouldn't go smaller than a 650cc injector though....

 
Rep Power: 244

hey andy, u don't know how much ur post means to me ... as of intake manifold .. im going to go with the d16y8?? is that good enough? I can't afford the freaking JDM fabtech. I have the Dezod v3 kit ... u said i would benefit greatly from a cam .. but then u said i'll hit 275-300 with a stock head meaning no pnp job? IMO port work is more imp than the cam for the single cam?? no?? jus cuz the head needs to breathe. hmm how much is it to convert to a return system? how do i do that? .. as for injectors, 650 cc? who makes them ?

 
Rep Power: 262

You are almost making 200 as it is on 6 psi........you want 250-300ish? For economy sake I would just turn the boost up to 8 psi, k-pro, & a cam.......enough said.....Anythin 250ish to the wheels is plenty. You won't be getting beat by much. I'm sure Andy stopped getting beat by at least 200-220ish to the wheels...he's probably close to untouchable at this point...Remember we weigh 2400-2500ish lbs...power is not everything.

i thought of doing that before but i just think about it .. i put together a pretty expensive nice complete setup .. and spend my money .. im working and making 10 grand this summer and instead of selling for s2k im keeping it for another 2 yrs so im jus thinking spend 4 grand on build and kpro i will be reliably @300 with a mild build and push it when ever i want , not worrying about spinning a rod i don't know how to do any of the work so i can't risk something going wrong .. i want to do it right . and even after this is done .. ill have 6 grand for school next yr which is more then enough. and im good for 2 more yrs having a DD and a reliable one without any headaches ..u see what im saying? .... witht hat said, i actually thought of getting exactly what u jus suggested.. but again im gona drive it for 2 more yrs and i weight 2700 lbs cuz i drive a 1.7eL haha

You need to relax and do some reading. All of this stuff has been covered so many times. If you're interested in a return system, just do a search on club rsx for it, there's a great thread that tells you every single thing that you need and how to do it. It's dummy proof.

I've already said that my head is the stock casting, no pnp on it at all, just a stage 3. I don't know how well the stock y8 manifold will do, to be honest but I know it isn't as efficient as a jdm fabtech would be.

Just slow down and take your time. Read and do some research.
