How To Select The Correct Turbocharger/Torque Converter?

[phil_long]

I def agree with what you're saying Steve no doubt. Some parts I consider cool guy parts, and others I just don't. When you mention that they were on the edge, that's something that I wouldn't want on my street driven buick. Yes, their combo worked wonderful, but pushing it to limits is something I would want to avoid, which is why I mentioned buying parts that are beyond what your goals are(within reason).

Most don't know who Russ Merritt is. Bottom line. Russ is one of the very best in the business...per iod. Russ' wife went 9.97 at 138 with a girdled stock stroke 109...think the crank was 20/30. Roller cam...Champion iron heads and I'm betting Russ warmed them over. Stock headers...6776 ...5.7 alky chip...Transla tor...9/11 convertor...th at's it. And Russ' wife...well... the lady can drive.

Air quality Most haven't got a clue...unless they're out racing every weekend in it spring to fall.

Torque convertors. People are hooked on LU's and will continue to wonder why there MPH is off. I've given up...

Driving ability. Some can...some can't.

XFI. On a 10 flat car you won't go any faster with it. The box is really shiney, I'll give it that.

Power is in the heads. JB Racing heads out flow Champions. Last time I looked there's a pair on my car. 7 flat at 100 all day on 23 PSI...a fat tune and a lazy 1.7.x launch. JB Racing is the best kept secret in Canada.

Dynos are a baseline as to where your car is at...and that's as far as it goes. They don't take into consideration wind resistance, driver ability, track conditions etc. Dyno sheets are popular with the Timmies crowd...

Unless your willing to get up at 4am on the weekends and hit the track to test/race...then you're not gonna learn all the little things to get these cars to run hard all day long.

Almost forgot. Most won't listen...or read instructions.

I see  some folks buying every known  part, to increase HP.

way over  built, not strength, but  way to big of turbo, inj, cam, valve springs, and the list
goes on.........why ? cause some one with no clue, told them to?

I actually like it, as down the road, at some point, they will  sell off  the car or parts,
and I get a great deal on underused parts.

95% of  these cars are street driven, yet have parts that are close to "race only"
my big issue  is valve springs, 99% have way to much spring pressure,

my we4  has oem heads, with  big valves, and about 2 hrs on a flow bench,
206 cam, 60lb inj, and a 911 LU converter, and old school TA60.
11.51@117,  and 24 mpg hiway, quiet, and as easy to drive as  it was when new,
it spends 99 % of its time  on the street,

seems you just can not  tell  some folks facts, as they wanna hear fiction, it must be  more entertaining.

I have no problem with those combos and believe you. just because you can run 10's or whatever does not make it a race car. however anything on your car that's not street legal does make a race car IMO.


 Race gas fiberglass parts slicks and include trailers and such do IMHO.


 In my case I drive to the track do nothing to the car go directly to the lanes after tech go around the water box to the beams .peddle it a bit till second gear and run 11.92 at 122. with a 2.1- 60 ft time. It does what it does, no excuses;
THE combo is close to Steves.


The distance between city blocks used to be 1/4 mile read into that what you may lolol

Steve, I think the combos you have listed are right on the money!

I would like my car to run low 11's or even a high 10 on straight pump gas.  I have run mid 11's on pump.  With more compression, good lifters and better turbo I guess we will see how it performs.  Who knows I might not have gained much.

We don't have E85 here either.    I'm stuck with 94.  I was thinking of tuning the car to 20psi with alky which should make it a decent performer.

Most don't run near enuf valve spring pressure. 130 lb valve springs on this flat tappet cam. Discuss amongst yourselves.

You are probably right about that Steve!  My 4.1 moves a lot of air.  I tried the stock turbo on it and it just chokes it, the exhaust wheel is too small.  So I would imagine the 68mm turbine wheel will probably add a bit as well.

Brad, I agree.  Lots of power to be made on the valve train with good springs, especially with titanium springs and retainers.

I thought Mohawk had some good gas what happened to that?
