Which system would make more power:

TPIS Mini ram intake, ported plenum, 52mm t/b, SLP runners.

vs

Accel TPI intake system (from jegs), TPIS ported intake manifold, ported plenums, 52mm t/b, SLP runners.

This will be put on my 305 tpi bird. I am wanting to try to make 400+ hp.

Here's what i'm thinking of so far:

Ported heads and new valve train
all new internals
Hot cam
weight loss
vigalante torqe converter
Chip
Crap load of tunning
Complete exhaust
ram air
D/R
not sure what gear yet
all new suspension


If i'm missing any thing please let me know. OH Yeah, and the reason i'm picking the 305 is because it's funny to see the faces of Mustang and 350 owners when you kick thier a$$ with a small engine.

 

i would get the miniram, My friend has it on his 87 iroc and it is awesome

 

Anybody else have any suggestions.

 

Holy cow! I had no idea you could fit that many intake pieces together!! A MiniRam, 2 TPI plenums, SLP Runners, and a 52mm TB. WOOOOHOOOO!!!!!!!!!! How do the 2 plenums attach to the MiniRam?

Tim

 

mistake in typing. it'll be fixed.

 

get rid of the slp runners on the mini ram

 

there arent any runner's on the miniram. all there is is just one big chunk of metal. it's the hole intake and the top piece all in one

 

Tim, obviously you don't know the first thing about TPI...

I suggest you check out TPIS's catalog for the most up to date information!

 

you guys are going to screw this poor guy up

 

Anyone that thinks they can make 400+ HP with a naturally aspirated 305 TPI is already a few bricks short of a full house. Better add a large dose of nitrous or some sort of blower or turbo to that list. :lala:

 

for a 305 you want to get the car moving so you need some torque...
with you heads ported and w/e cam u choose you have you have much room for improvment in the intake....
IMHO id go with the tpi stuff...you can make helle torque and some good hp


you can make 400 horse out of a 305 tpi....its difficult but it can be done

 

And monkeys could fly out his ***... it's difficult, but it can be done!

Miniram is not the way to go... the bore x stroke of a 305 is not condusive for spinning up much past 5000 rpms where something like a miniram will shine. You'd better focus on building TQ and sticking to 1/8 mi. tracks... and BTW- no Mustang owner is going to be upset if some kid with a 305 that he sank thousands into beat his stock 4.6L.

 

Damn, the truth stings! Well, i would stick with the ltr set up too. This brings up something i have been wondering, is there anyone with a miniram on an n/a 305? I have not seen one.

 

Don't know of anyone with a Mini Ram on a 305, there was one guy floating around on the board with an LT1 intake on a 305. I haven't really heard much about it since his initial post.

 

LOL

 

come on guys.... i think if ya stuff a huge cam and heads on it and tune to hell and back it's possible........

yeah alot of people don't want to use the 305 because of the bore size... if you are really dead set on a 305 try that 334??? stroker kit and do as i said above... that's the best chance i can really think of.....

theres always supercharging and nitrous....

 

Yea check the catalog under 400hp 305's. You've got to think outside the box to reach power levels that high.
And while the TIG welder is out, might as well throw on two
sets of AFR heads!

 

I'm not even sure you can use AFRs on a 305... the valves are too big for the bore... especially when you mill the 64cc chamber down to a 58cc size to keep the CR high enough.

 

TPIS Mini Ram would definately be the way to go over the Accel unit IF you have a 350 or better. As mentioned earlier, check the TPIS catolog for most recent information. You will find that TPIS only recommends the Mini Ram for 350+ engines. If you question their recomendations just give them a call and ask them what they think based on what you are putting into your engine. 952-448-6021, Mon-Thurs: 8am - 6pm and Friday: 8am - 5 pm. I have talked to them in person about this issue of Mini Ram and the 305 as I only live a couple miles from their shop.

With all the new parts (not to mention money) you are talking about investing, I think you would be much happier with a larger displacement engine that will more easily attain the A$$ whipping power which you search.

Also, I think it's more of a cool factor to have a 350, 383, etc vs saying you have a 305. Your comment about beating someone with a smaller engine KILLS me. Who cares what you are running. Any way you cut the cake, winning is winning! I love beating up on the Ricers for that very reason, they think their little 4 banger w/ fart can will keep up! LOL As they say, no replacement for sheer displacement.

my $.02

I was joking Smartguy. The only thing I would use TPIS's Claims for is Wiping my ***.

 

Back in the day, about 1993 or maybe 1994 when I was heavy in the street racing scene out here in So.Cal. There was a guy who had a 1985 IROCwith a 305 and it had your basic run of the mill mods (flowmaster,K&N, 3.73 gears) blah,blah blah...It was somewhat respectable for what it was. Well one night the owner of this 305 IROC decided to hit up this 89 5 liter mustang that was built to the hill including a vortech, if this stang didn't run low 12's it didn't run at all.

So everybody from the local hang out meets at the secret strip section in town to watch these two cars run, with the majority of the people just there to watch this stang spank this lowly ol 305 camaro. Well they raced and let me tell you, up until that point in my life, I personally had never seen a third gen camaro run sooo hard in all my life. This camaro beat this 12 second mustang so bad that the mustang shut down after 3/4 track, at least 4 to 5 cars. After that race we never saw that car again at the hang out.
About 6 months later a friend from high school was lookin for a car and he ended up buying this infamous camaro and painted it a different color so no one would know. So when I ran in to him again I was dying to know what was in this car. It was the stock 305 with mentiond mods and a NOS wet direct port system with 175 hp jets. I guess the guy who owned and raced it that night worked for NOS at the time, and he was R&Ding that kit they sold or still sell that has the black TPI runners with the direct port nozzels already plumbd in.

So it is possible to beat a lot of built stangs out there.

 

Building your 305 to 400 horses isn't impossible. It's just that you seem set on natural aspiration. I don't know if you could achieve 400 horses with this, but heres my suggestion:

You need the torque of a LTR setup if you are dead set on building that 305 instead of a 350. Go with something like
-Edelbrock base
-Edelbrock runners
-Thorough, clean upper plenum work.
Note - you're striving for as much power as possible without a blower or laughing gas, so it'd be extremely smart of you to have everything in the LTR setup portmatched and ported out as much as possible.

I believe AFR makes a 180 or 185 head... correct me someone please If i am wrong. Whether you get a shop to work your stock heads or buy heads out of the box, make sure you take into account the powerband of LTR.

You'll want a cam with less lift and more duration to eat up the LTR's personalityand make happy with the heads you chose.

Rebuild the bottom end with pistons that'll yield you 10.5 to 11 compression. You plan to run pump gas, so don't go higher than 11, as youll need to run 91 octane now.

Small tube headers will do for a 305, hi flow catalytic converter, mandrel catback with hi-flow muffler.

2400-2800 stall converter. Vigilante is a good idea, but the most expensive.

Weight reduction: I would focus on rotational weight. Lighter wheels, lighter driveshaft etc.

Raer gears and drag radials will help you achieve nice times, but have nothing to do with horsepower directly. I'd say M/T et streets, and a 3.73 posi would be a good combo to use.

That's about what I can render as being a pretty f*cked up 305... good luck man. Don't go broke trying!
