Just curious of just how much of an improvement I would see with this base over the stock piece. I dont plan on porting it out, although I know it would help, but I dont have the tools nor the know-how! So how many horses should I see(approx.) with my current set-up(mods in the sig.)? Would it be worth the money? Thanks for any thoughts on the subject.

'91 TA, 305TPI, mild cam, stock heads ported and polished, ported plenum, SLP siamesed runners, edelbrock TES headers, flowmaster 3" cat-back, 3.73 posi, K&N, custom CAI, hypertech stage II chip, march underdrive pulleys, (1/8th mile: 9.45@74.28mph)

'95 TA, Borla exhaust, K&N CAI, !MAF screen, 160 stat, March underdrive pulley, Richmond 3.73's (1/8th mile: 8.84@ 79.42)

 

I saw a pretty impressive gain with my LPE base. I really don't know how it compares to the Edelbrock, but I would bet you could see a good .3 drop in your 1/4 ETs with it and the mods you have.

Sounds about right...get the Edelbrock base from Jim Pace performance Parts...cheapest price brand new, $330...The Accel base is a nice piece though. It's also pretty damn expensive!

 

Just by adding the Edelbrock base on my 350 tpi I improved by close to 2 tenths which is close to about 20hp.

I agree, the experts in their tests say 15-20 hp on a stock 350.

 

Hmmm, 15-20 on a 350, I wonder if it would be about the same for my lil' 305? I was wanting to have Ed Wright(or similar) burn me a custom chip too, I really think it would do wonders over this hypertech chip. Hopefully with the base and the chip, I'll be able to knock 2 tenths off my 1/8th mile times. I guess I'll have to wait and see! Thanks for the replies guys.

When I had my 305 TPI, I had a bunch of mods for it like, Headers, pulleys, chip, cat back, K&N's, shift kit, 1.6 RR, and I bought the Edelbrock base and runners and I was slower in the 1/8 mi. I think I dropped a 10th or 2. Just my experence.

I realize this post is mega old, but tommarow I will be finishing the install of a accel base. Any guesses on what it will gain?

Basically I have a 383 with sportsmas heads and a full exaust, with my cam I make peak power a 5500.

The intake is completly stock, down to the air filter.
