2.4 with a t88

[martyboss]

project car ,the spyder is awd now,we try too many things so far I running 2.4 with holsett hx-40 as compare to t66, have cast big mitsu housing ,I dont se problem with t88 have 25psi before 5000rpm without nos

Then a t67 or a t4 would be a better choose for my car? Why do you say that, I should better off staying with a 2.0 or 2.1 with a big turbo. And why would I ever think of going with a 16g? I want to make real power, not 300 or 400 hp. I really would love catch Shepard someday. I know that would be one hell of a thing but, that is what I want out of my dsm.

It's Shepherd and you are in dream land. I understand everyone has goals and all but be realistic man. You are never going to run that fast, it's just not going to happen. You need to start small my friend, thats why someone said get a 16g. You may have experience with "cars" but not with DSM's. They are not a Honda, Domestic or what ever you come from. You have a lot to learn and that is quite obvious. A T88 is not your answer either. You would be best tuning a mildly modded car and understanding how these react to it. Get used to driving it at the track. Then upgrade to something larger. If you buy some Huge turbo right off the bat and throw the car together you are just like every other winner who thinks parts make a car fast. Thats not how it works and thats why people have ran 11's on a stock turbo from a 1g and a 2g. Because they know what they are doing and if you really want to go fast you will learn the right way and take your time. Regards,

Quit while you are behind. Seriously, I am not joking. Learn how to use proper grammar also, because I could type better when I was 6.

 

[martyboss]

like man sad he run 16g is waste of time on 2.4 if he goes spend right $ he will be there BTW on HWY 16g is too small on 1/4 not bad for what you spend on mods.

well I live in states for 4year didnt speak any english before (I know well 4 another languges so far boss.

Why does every topic on this forum always have to have people that dont agree with something start flaming?! grow the #### up... if you think its too big..shut up. if you think he wont spool it...shut up, its not your car.... so who cares!?

if they want to try something let them.. they will learn very fast about what works and what does not work. Did people flame Shepherd when he first bolted on a Full T4 turbo??? rather than the 3rd world turbo 20g? No, they shut up and he ran a hell of a lot faster and now everyone is following the band wagon.

if a person has a completely stock motor and wants to put a T78 or something on it.. let them, who are you people to stop them or argue?

im sorry.. i just hate when this shit happens. makes the people that really know shit frustrated and turned off by this board.

If you are all in a tissy with me then let it go. I am just trying to help the guy. A T88 is a lot of money and a serious waste of it at that. I still say start with a 16G. When you first learned to drive was it in a Formula 1 car, no it wasn't. That rule applys here.

 

[Stanford]

Well even with that said, it is still doesn't change the fact. Just use a spell check program. Not trying to insult you or anything. You just won't get taken seriously ever when your posts are written that bad. Not to mention having more than 1 of the same kind of part in your profile.

 

[98talonAWD]

actually i went from stock( for a couple months) then to this a year later.... so basically yes... straight to a formula 1 car! hehe

im not pissed at you im just saying in general... there are a lot of people that seem to reply when they really dont know what they are talking about. you say that " i just want to help the guy"... well i agree with you... thats why i get mad when other people that dont know jack start saying shit like it cant be done.

a 2.4L with proper head work and every other mod and a nice shot of juice(75-100+) should spool a T88 by 6000-6500 pretty easily.

Not the same as a T88.

 

[martyboss]

well finish that car you talking about and will see if you need any juice to spool

I'm working on a tech article of VE, friction and other differences between a 2.0 and 2.4....
QUOTE]

I would be interested in reading what you have written so far. PM it to me if you could.

Right now I mostly have EAPro data saved as text files for importation into posts or excel...

There are large differences in mechanical efficiency due to the longer stroke. More strokes negative effects are ring friction, piston thrust (pressure on skirt) etc etc.

Let me know what aspects are most important to compare. I thought of making it something even ricers could understand or going full on straight up tech. Friction HP comparisons are terms that even the densest will understand... Peak piston speed vs average piston speed, TDC G forces, BDC G-forces etc etc many just will be like .

 

[MNGSX]

Says who?




Goes without saying.



Hmmm..odd as how MY 2.4 seems to spool the same turbo I had on my 2.0 ALOT sooner.As in almost half the rpm-b16g clipped 10 deg,7cm housing spooling at 1800 vs the 3400 it used to take.Yet some how still revs to 8500.

While you're working on the differences on a 2.4 vs 2.0 dont forget that average piston speeds are slower per given dynamic volume on a 2.4.

You mixed some of that up.

I was saying a 2.0 wont spool at a lower RPM than a 2.4....... You can move more air thru a 2.0 than a 2.4.. Just not down low...

I see 2.4's as great street and strip engines. I see 2.0s as great drag race engines.. Like 383's are great street and strip. All the fast tube frame small block drag rails.. SBC's that run along side BBC's (they get a lower min weight) are seriously destroked high winding mo-fos..


Before you go maybe you should look at the stroke length of ken dutweilers turbo engines and how a high rpm short stroke SBC can spool a BBC size turbo.

Go ahead go call Ken a toolbox... I dare ya.

Yeah right. Do you know how big a PT88's exhaust side is? The wheel DWARFS an innovative R-trim like comparing a Q-trim wheel to a Stage 3 T3 wheel. It's massive. It didn't make 24 pounds of boost untill 5500 RPM's on a friends 347 inch motor, it is gargantuan even for a big V8 that is to see any time on the street. I would venture you wouldn't see 20 pounds of boost till the 7000 range, even with a hit of juice.

this is the turbo I was looking at

http://www.turbovisions.com/catalog/item/1486966/1060234.htm#image_1

And I would love to try a smaller turbo but, I sold the motor that came in my car because when i bought it the bellhousing was shattered and i did have the money to buy another tranny. So i sold the motor and if I am going to spend a good amount of money on a turbo it is not going to be $600 for not little a** big 16g. I don't fill it would be worth my time. I as in my first post would a 2.4 spools a t88. Not should I go with a big 16g instead. And if I am going to spend money on building my engine it is going to build for alot of power.

That's awesome man, good luck. By the way, good luck competing with anyone when you can't even replace a bellhousing.

Thats a Greddy T88

When you finally figure out how to convert CFM to Lbs/min let me know what you think about how 850 CFM (*greddy T88) converted to Lbs/min compares to a FP 3575's 75 lbs/min.. Or even a FP3065's 65lbs/min.

I know already...

Maybe you should look into some Ken Duttweilers turbo'd engines your self.Lots of strokers--lots.

(they get a lower min weight)

Sooo then what youre saying is if the car is lighter then some how that makes the shorter stroke better because of a rule on weight,a rule that doesnt apply to dsm's?

Anyway,I'm interested as to how a 2.0 flows more than a 2.4 if everything else is the same.

The bell housing wasn't the only thing that was wrong with the tranny the guy that owned the car before me tryed to do a redline drop and shattered the bell housing and destroyed first gear and the clutch and flywheel that was in the car. So don't start talking sh**about something you don't know anything about.

 

[MNGSX]

His street strip engines or his all out racing engines and HP record engines....

Oh yeah... Maybe the same thing applies here too! Wow what a concept.

Sooo then what youre saying is if the car is lighter then some how that makes the shorter stroke better because of a rule on weight,a rule that doesnt apply to dsm's?..

:laugh: ... NO IT's JUST A HANDICAP TO MATCH THE SBC GUYS WITH THE BBC GUYS......... Why the f*ck would you think I meant that to mean anything in regards to DSM's... Its just the class of racing where you will see that engine design.

Anyway,I'm interested as to how a 2.0 flows more than a 2.4 if everything else is the same.

Stay tuned... I'm going to wait untill I get the project "a little closer to TDC" before I light it off.


BTW ken is'nt the only one....

Meaney said, "this is a GM DRCE-based turbo engine that'll rev almost 10,000 rpm--you figure it out." So, we said that's a giant bore, a relatively short stroke, and a long rod. Meaney answered, "You're on the right path...." Check out the details we could get...

 

[na90dsm]

yea ever get sbc and bbc guys together, its never good. its like ford and chavy guys arguing all over again.

I know already...

Just a little clarification. There is noe FP 3075 you (maybe one other person) keeps mentioning the 3075 when in reality it is called the 3575. It does not use the gt30 turbine wheel, the "30" designation does not apply.

Matyboss- Your bolt on hx40 doesn't hold a candle to a true t88.

 

[MNGSX]

Yes I goofed... I was typing fast...

Every other FP was a 30XX...

I'll fix it.

It's still 440 cubic inches, and the only reason he didn't go with more was because of class limitations. Using more bore than stroke in that situation makes sense because a 4.625" bore with a 3.3" stroke means the head is flowing a whole load more air than it would at say a 4" bore and a 4.4" stroke. Look at NMRA pro-5.0 guys, you don't see them running a 3.3" stroke because they can only take a SBF to about a 4.185" bore, but most of the competitive cars are running 400+ cubic inches and a 4+ inch stroke. You can't paste a general statement that destroking/shorter strokes are great for turbos across all engine platforms.

Well that web page is DEF way off. A Greddy/Mitsu T67 25G flows 1000CFM and a T88H is good for 1000HP. Big difference. Titan Motorsports uses a T88H on there low 8second Supra. Also Boost Solutions made 712whp on a reg T88 not a T88H on a 2.3L Evo VIII and I know a 3065 has not made over 700whp on boost.
