I am looking at getting a new base and runners. Although heads and a cam are 2 years away what do you all suggest-- TPIS, ACCEL, AS&M etc? I want to be solidly in the 13's .

------------------
350 TPI, 700R4(rebuilt), K&N's, MSD 6AL, Headers, Flowmaster, 160* stat, airfoil, MAF screens cut out. 13.88 @ 101.18 mph

 

I suggest TPiS, and Here's why: TPIS, which is a $475 intake, not only gets you a good intake, but port matching as well. According to their catalog, they put about "an hour's worth" of porting into each one. Given their level of experience, I think an hour's worth of professional porting services is worth about $75 to $100, making their intake quite price competitive with the remaining intakes on the market.

Do you think the TPIS base with AS&M runners would be worth 2-3 tenths in the 1/4 mile?

Do you mean 2 - 3 tenths "by itself?" Probably not. However, if you've removed the other bottle necks from the system, then yes. You've already modified your MAF, and added a good exhaust system. If you be sure that your plenum is port-matched to the throttle body, and gasket matched to the runners, and the runners gasket matched to the intake, and the heads gasket matched to the intake, then yes, I think 2 - 3 tenths is possible. In fact, witha 13.88 at 101 MPH, aren't you close to needing a torque converter and drag radials?

How about that cam?? Have you considered swapping in a 212"ish" duration, 112 LSA type of cam? Add a $150 2500 stall converter from turbine technologies and you should be cutting 13.4's.

I would love to do a head and cam swap but like I said its not in the budget for quite awhile.
Since last year I have added drag radials and also a ported plenum. I couldn't go any quicker than 13.99 @ 100 for some reason. Maybe a tune up is needed?
This is why I'm hoping that a new intake will do it for me.
As for the convertor, I had my tranny done 2 years ago and can't remember if he put a new one in or not. It sounds stupid but I'll have to go see him and ask.

 

Anyone else????

 

What's the diffrence between TPIS andAS&M runners? Is one better than the other?

 

i dont think it would hurt to look at edelbrock products, ive heard some quite nice stuff about them, but, i havent used them so i cant tell you from first hand experience. as for the cam, i'd get heads, THEN a cam to really make use of the higher LSA that you'll have. actually, yes, i'd get the heads, then teh cam and the T converter together, but thats a ways off as you say but yes, if you want to spend the money for the base and runners, i'd do that and all the other small, inexpensive things usually done(air foil, air filter, headers(sort of inexpensive) and so forth). good luck

 

88 Iroc BOB, I am a fellow Ontario resident who is thinking of doing the same mods to my 305 TPI, what kind of prices have you been getting and more importantly where are you looking for these parts(US or Canada). Price is going to be the determining factor in my purchase. I 've got to figure that any aftermarket base and runner setup is going to be less restrictive than OEM.

 

Hey zedder!
I'm down near Windsor-- right across the border from Detroit. I have not been able to find any place around here (in Can.) that can help me out. Everything that I have bought so far has been either from Summit (yes the brokerage fees and taxes suck not to mention the exchange) or speed shops in Detroit.

I'll probably go with AS&M runners with a TPIS base. This is the part that sucks. Approx. $850 U.S. for both = $1200 Can. OUCH!!!

No one ever said going fast was cheap right.

Bob

Is the Edelbrock base every bit as good as the TPIS? I think I want the AS&M SS Runners but am still debating on the base!

TPIS's base is ported. Thats the only differance. I say get the Edelbrock and and port it yourself.

 

I say you ought to drive your car across the bridge for a weekend, stop off at a friend's house, install your speed parts in his garage, then drive home on Sunday with a fresh tank of american gasoline, and a shopping bag full of inexpensive Christmas presents. The brokerage fee would be a whole lot less money, would it not>>?

 

There is no duty on car parts any more, but you are still subject to GST and possibly PST if you declare it. You run the risk that any time in the future if Customs pops open your hood, they see the aftermarket parts and enquire about it.

I know a few guys with modded cars that have been checked by Customs for modified parts.

 

So, they make you carry all of your receipts in the glove compartment, eh? Hmm!

BTW, Glenn, Your message counter shows you as having written 4000+ messages. I've always wondered this for the longest time, but *do*you*have*a*life*outside*of*thirdgen.org???

Oops! Then again, I think I just logged message 701! I probably waste an hour a day on this site. Extrapolated, this equates to about 5.7 hours for you!

I would really like to know how TPIS does "port matching" when they dont even have the heads there that they are matching it to? If you make the intake too large compared to the port it is going to flow worse than if it is too small compared to the port. I think I would buy the less expensive one and match it myself, that way I would know it matched.

WS6...I am an extremely fast typist and I spend probably less than an hour a day here too.

 

Roy, they port-match it to a Fel-Pro gasket, which they include in the box. You're supposed to match your heads to the same gasket, that way there is no mis-matched ports.

 

Still doesnt seem like a good idea to me unless your heads are off anyhow. Now you have to remove your heads to make it work right, because the intake will surely be larger than the head this way. The important thing with airflow is not to have a step in the wrong direction. IE smaller into bigger is OK but bigger into smaller is mucho bad.
"If" the porting they are doing is actually to match the head and not inside the manifold itself then I would definitely not spend the extra unless I could then match the heads to the gasket also.
