Hey everyone, i need help choosing an intake. I have a stock 91 350 tpi with a procharger. She is makin 400 hp and 458 tq. I am not sure if i should switch to a holley stealth ram intake, edelbrock vic jr efi with 90 degree elbow, or buy a lower intake, runners, and tb for my tpi..

I plan on using the intake on a 383 or 388 i would like to build. And im shooting for 600-650 hp with the supercharger.

So let me know what you guys think would would be a good intake for for a 650 hp supercharged application, and be a good choice for my stock 350 right now.. THANKS

 

I would think either would be fine right for that power level but I recommended the SP before in the email. I think it would have better air distribution than HSR but hard to say. I dont have any data nor have I seen any for HSR vs others under boost.

 

Hey orr!! haha ya that is what i am thinking, i remember seeing somewhere that i think you were saying distribution to number 7 cylinder was less or something with your hsr.

Also are you running a 730 ecm? and what computer software? i know there is a whole bunch like tuner pro , and all that, i wasnt sure what is a good one.

 

I got the 730 ecm but using code $59 for my boost. I use tunerpro RT version 4 not the new 5. havent tried that one yet but looks good.

HSR was abit richer on the last cylinders compared to the front for me but that may or may not be due to the nitrous system i ran. However I beat on that car for awhile after my last nitrous spray and when I tore it down the back cylinders were still blacker than the fronts. On boost I've heard the rear will lean out due to the extra mass of air being forced to the rear. I just dont know how bad it will be.

Most all custom forced induction setups use a tapered plenum with it smaller in the rear to limit air flow to the back cylinders. HSR being big and square may have leaner rear cylinders.

 

oooo ok. I also saw somewhere that people were saying something about the intake gaskets for the stealth ram can't handle boost, but i don't remember where.

Did you do the code 59 yourself? I found a step by step guide on how to do it and i started getting lost. haha

 

I converted everything over to use the code myself and eventually tuned it myself but I did seek help on some idle issues and other general tuning issues here on this board as well as the syclone/typhoon guys. THey helped me figure it out. There are some good tricks to use when working with it. Getting a goods starting bin really makes a difference.

 

O ok. Well ill definatly be trying some kind of software once i get a motor built.

I just don't want to spend $1000 on an aftermarket computer, when i can learn to do it with the stock 730 computer.

How did you mainly learn how to tune/do the computer stuff? Just on the forum?

 

Check your thermo housing to hood clearance if planing on running the elbow to the front on the SP
Thermo base on TPI is 1 1/2" from china wall
Victor E is 4"
Some have capped the thermo outlet , tapped the front of the intake and used a remote thermo to get room to position TB in stock location using a elbow

 

Yep basically. Studied on here, then took it to the car and slowly got an idea what to do. Started on stock L98 with bolt ons so I got the hang of it without worrying about screwing it all up THen did my 383 with a base tune i got from pCMforless but as it turned out i had to change the majority of it anyway but it was a good enough chip to start the car up and break it in on. After tuning that car I got a good feel for it. These forums really help.

My twin turbo project was a handful but basic knowledge i had from previous tuning experience even tho it was MAF compared to MAP, and from this forum enabled me to figure it all out. Being that code 59 originated from the syty guys, go visit there forum and chat as well as code59.org obviously. Worked for me but i still have abit to learn and some minor tuning issues to work out.

 

Good point about the housing height. Mine sits way up and I had a custom elbow with 3" rise from manifold side flange to throttle body centerline and it requires a 4" cowl hood to clear. A 3" may clear it but it would be very very close. The 3" rise on the throttlebody leaves alittle over half inch clearance i believe with the waterneck i'm using. A 2.5" rise may clear this waterneck just fine but depends on the design of the elbow.

Best bet is to mock one up in cardboard and trace that pattern on paper for someone to custom build it.

 

Hey orr, so i decided to give the hsr a shot on my stock motor and see what it will do.. I plan on getting heads and a cam also, but im not sure which heads to go with. Jegs sugested some edelbrock 60859 performer heads.
165cc Intake Ports
60cc Combustion Chambers
2.020'' Int/1.600'' Exh Valves
1.460'' Valve Springs, .575'' Max Lift
3/8'' Rocker Studs
I was thinking of some afr's but not sure...

 

Buy good heads now so you can use them later on the big motor. AFR 195's are good choice. you can easily make 600+ on a 396 motor with 10 psi. I know i have on my 401

Edelbrock 165's are no better than stock

 

ya thats what i was like, what?!@3... haha.. if i got those heads i would have to get them ported like no other for when i eventually build a motor.

I agree with you and get some afr 195s so that i can put them on a future 396 build. Im just not to sure about doing heads, cam, and the hsr on my stock motor. I would hate for pieces of a piston to hit some $1400 afr's. Maybe i should save up for a forged motor. haha To many options!!!..
