305 Power
DOES ANYONE KNOW IF A 305 HAS BEEN TURBO-CHARGED YET OR KNOW IF THIER IS ANY WEBSITES THAT GIVE INFO ON HOW TO MODIFY THE EXHAUST MANIFOLDS SO THIS CAN BE DONE
82resto is currently doing a turbo buildup on his GTA 305 5 speed. He bought a set of twin turbo manifolds but decided to only do a single. Which means he's selling the other manifold, if he hasn't doen so already. The other one he is selling he's also including an slp 1 3/4 header for the other side. His email is in te members area, but if he doesn't check it very much it could take awhile to contact him.......... unless you email me and i call him and tell him to check it.
the main thing holding the 305 back (in a build up) would be the small diameter cylinders. They limit the breathability of it. You cannot run big valves, nor high lift, for fear of valve shrouding and what not - that why people always say f*ck the 305! :lala:

Pay no attention to the 350 weenie brigade :nono:
A 305 with a turbo should hit 13s or 12s without many problems. There is a guy on this board named Willie, from Phoenix, who has a supercharger on his 305 and he's into the lower half of the 12s :hail:
A naturally aspirated 305 can get into the very low 14s or high 13s on a really good day.
If the 305 is what you have and that is what you want to build then do it. The 350 weenies won't be smirking when you kick their butts in the quarter mile
Also, talk to Apeiron. He has used turbos on a 305. Send him a private message through the message board here on thirdgen.

Yeah! 305 power! :rockon:
Why dog on the 305 anyway? It's better than a 6 or ::gasp:: 4 cylinder.
Is there really _that_ much difference, assuming all other things are equal, between a stock 305 and a stock 350?

Other than the 45 Missing Cubic Inches, or the Fact that the 305's bore is too Small To Be able to use any decent sized valve in the head w/o it hitting the cylinder wall...
I guess not...

Funny, isn't it, how that same valve/head combo will work just fine in a 305.
Time to put your mind in action before your mouth, Bort.

FYI, many of the fastest 350 powered thirdgens run AFR heads, which come with 2.02/1.60 valves. How do I know this? Well I don't have any factual numbers to prove that the fastest 350's use AFR heads, but then again, you don't have any factual numbers to show the fastest 350's use 1.94 valves.

hmmmm.......
BTW, I'm from Tucson, not Phoenix.
There's a local guy running a TTA. He has to push 20-psig boost to run high 11's. I saw him run a low 11-second pass, but it was with 26-psig.
Bill, I'll take you on in a heartbeat on ONE condition; that I run the same boost figures as you.... The times in my sig are with "only" 10-psig. I'm now up to 14 but don't have any track results yet..... wanna run that puny V6 against my puny anemic 305?

Getting back to the original question,...
Andriis Skulte has been working on a twin-turbo setup. Checkout his page --> HERE <--
Might also be helpful reading for those with NA LB9's. I believe he got a best of 13.55,... without removing the valve covers!

I think it's safe to assume that neither the TTA or Turbo Buick boys are included with the statement that "I'd rather have a 305 that a V6". Those V6s are pant wettingly good. But yes, a 305 is leagues ahead of say....GMs 3.8 V6 or FORDS V6 as far as getting more hp and torque from them is concerned. I'd take the 305 over a standard V6 any day of the week.
Everyone's entitled to my opinion, and there it was

Gay Boy,
For starters, I'd bet $100 that your car (which is what exactly?) would get walked by that puny 305. Why sit there and talk smack about someone elses car? There's no point.
There isn't a lot on there that couldn't be switched over to a larger motor, should Willie decide to go that route. I'm sure I'm not the only one here that likes the fact that has has gone his own way with regards to building a fast car. I enjoy reading his posts with his tech findings such as the effectiveness of the intercooler set-up and his water/methanol injection. What usefulness have you been able to find and report to others?
Maybe you should face facts, you're an idiot! In all of your posts that I've seen there isn't one that says anything of any interest. Why bother posting then? Bored? It would seem so. How about putting a noose round your neck and hanging yourself from a rafter? It could be fun, and it would certainly kill off some of that boredom you seem to have there, along with yourself hopefully.
I carried out a search to see what other use you were to people on this board and, surprise surprise, you're officially classed as useless. The only thing I actually gained from reading your other posts is that I now see where you are comming from, which is nice because after reading your post here your origins were infact somewhat on a mystery to me.
Kindest regards
Rob

about the TTA, are you sure he's not running a otherwise stock motor? I know stock motors don't handle more than 20psi or so.. He must at least not be running a very serious turbo.. something. It doesn't take 26psi to run low 11's. My only guess is he had mismatched parts(turbo/stall c.) or is out of tune.. i dunno.
so *****, when the hell is your page gonna be updated?
i loved reading the progression from the start to your paxton/n2o level, but you've done tons since then. I remember you saying you didn't actually make the page, could you slip the guy a buck or two who made it to get going on the update?

I thought he discovered that it was actually a 350 after he tore it down?

DownUnderIroc has nothing to do with the updating, it's me. Before it can be updated, I need current pics. I use a digital camera from work but it's extremely hard to get, especially over a weekend. Once I get it, I'll snap current pics and send them to Jim. Therein lies the bottleneck.

Willie,
I would love to run you or anyone for that matter, but you especially because that lil 305 of your's is nasty. Running the same boost levels as me is fine, if you can
. But, all things being equal, I still need another 2 cylinders and 75 cubes, so I think you're gonna have to deal with me running more boost just so I can make up that difference
You need to drop me a line, I haven't heard from you in a very long time. I want to hear an update on the car and the family.
Take care

Hey Bill,
We haven't talked in a while. I'll give you a buzz sometime. Your number is still the same, I presume? Or give me a call at work on my toll-free line.

Normally, I don't even bother responding to "junk" as below, but this time, I'm going to make an exception. Here goes....>>

Hmmm..... Let's see, I've got less than 10k in my car. How much does an LS1 equipped car cost?? I've reduced my E/T by four seconds (can anyone else say that?). I wouldn't call that "little returns"... would you?
Bolt on LS1's run neck and neck with you.
Really? So far, none have. Send me your address and I'll send you video (proof)....
You sure like to talk a lot of crap like you know a whole lot, but when it comes down to it, your puny 305 gets its *** handed to it by most mildly built, naturally aspirated 350's.
Wow. You sure sound like you know all about me and my car. I have yet to lose to a street-legal 350. In fact, my last outing at the track yielded a win against a modded 440 1970 Cuda (license plate -- 1 HOT FSH).
Let me make a suggestion. Before speculating, get the facts. Speculating makes you look really bad, just read the replies after your original comments about me and my car..... Have a nice life.

I'll guarantee that all of you will kick the daylights out of my 120,000 mi stock (to my knowledge) 305.
Eventually I will get a big and nasty motor to tear my wheels apart, but until then, I will enjoy driving my T/A becasue at least it looks good (for being 13 years old). Anyone gotta winter beater they want to race, I might be able to beat you!!

I'm not too sure about the whole GN/Thirdgen war, but as someone already mentioned, I read about Preston Smith's 85 running high 9's on a nasty Vortec blown 305. He was running Trick flows with 2.02/1.6 valves, Supposedly you can run 2.02's on the 305 with Trick flows because the valves are rotated away from the cyl wall. The bore is small on a 305 but doesn't that support better combustion in supercharged/Turbo'd applications? (correct me if I'm wrong). I guess that 85 has a single turbo and a custom water/air intercooler now and is faster than it was with the blower.
This guy knows his stuff, I wish he could help me with stuffing a turbo on mine, then go 800horse Supra hunting

Ask monty about the turbo
BTW.......................A Well built 305 will run just as fast as a 350.
All the parts are interchangeable, you guys should all just stop worrying about 305 vs 350, you sound like Mustang owners bitching about the 302 vs 305. Jeeze!
It's all a bunch of
we know we're faster than the stangs, they are jealous, that's why they always bitch
