is it possible to get that out of a 20b
got_that_boost: i got a v-mount intercooler, bridge ported, modded rotors and housing, hks t51r spl, msd ignition, tein ht suspension, cusco sway bars and front/rear struts, roll cage, brembos gt's, modded trans- driveshaft- alxe, 4.300 final gear, etc

hes on yahoo if u guys feel like talking to him and he lives like 45 minutes away from me and wont let me come see it think its a bunch of bs

 

Is this him wanting to know, or you wanting to know?

If he needs to ask and has all that stuff (assuming) he needs to get a reality check if he needs to ask, and if it's for your curiousosity's sake, then it's cool.

Also might want to post this or have it moved to the 20b forum. More knowlegable people on 3 rotors in there.

Peace,
Matt

 

It may be possible but in this particular case....

 

905, nah, don't think so.906 on the other hand.........

 

I agree. The turbocharger alone doesn't move 100lb/min of airflow to make 900rwhp let alone other problems with the setup.

B

 

The T51R SPL is rated at 1000PS, it might be possible to make 905 BHP on a 20B.

 

We should have him come race mine in town sometime...

 

A better Question... how does all thea stuff other than the engine generate 9 some hundred horsepower??

Damn I need them shocks dude... I can get 1000 HP with them!!

And the Turbo being "Rated" at 1000 HP??? COOOOOOL!!!!!

Soo... if I get it and put it on my sons 3.5 horse Gokart it will make 1000 HP????

How about my 10A??? Putting that on will give me 1000HP??

How about it I put it on a 990HP N/A Big Block Chevy.... will it ONLY give me 10HP??


That is like Rating a Intercooler for X horsepower.. Silly.
Wanna argue it.. ask EvilAviator.. LOL I am sure he can get REAL long winded in your ear on it.

There is more to making 1000HP than simply the parts you throw at it.

 

The schmuck was just asking for clarification on what he read on some web site, Play nice and just explain why its not probably making that much.

White wide body:

turbine size alone will not give you an adequate basis to rate horsepower, things like actual port design, injector sizing, exhaust etc will make a huge difference, I would guess more like about 600 or so would be more accurate in the hands of a general tuning shop, a really good tuner could probably pull maybe 750 or so, but a T-88 in a really big trim size would be required to move enough air for 1000 horsepower. unless he has nitrous also, then once again without a truly great tuner, the engine wouldn't last long enough to dyno.....

 

With proper fuel enrichment and ignition, yes its possible. They did it w/ that RX-8. But the likely hood of it. Maybe not. Slap the thing on a dyno and find out, thats the only way.

 

Why waste his time?

 

Big words little man. Then again, my car won't be running for about 2-3 more weeks, so assuming his moves faster then I can push, he'd win. Now in 2-3 weeks... traction becomes my enemy.

 

Soo DId you change the HORRIBLE POS Smog heads on that lump of turd? Or ya just gonna let uit wheeze out a blistering 200 HP choking through the old cast iron slugs??

Cause with that list of parts its gonna be a real lump of turd with decent torque. And by decent I mean in regards to a rotary. Not a V8.

Im half tempted to run the numbers on that engine.. just to laugh

BTW.. it WILL.... it WILL be a BLAST to drive. But dont get too cocky.. someone with a decent TII will bust yer ***

My 302 84 is lots of fun.. but it is simply a rear tire smoking oddity.

Driven a VERY well built 302 HO powered C-6 having blue with white stripes FC. It was mediocre. The owners TII was as fast once things got moving.. with a AFC and the bolt on mods that everyone does.

Basically.. be careful until you are done.. that engine isnt all you are trying to make it out as. Not all V8's are the same.
Food for thought.. Ask ANY V8 hardcore racer what happened to the world of V8 Horsepower in 1972-73. For those fo you too young.. it fell through the floor because of emissions and insurance issues.

Your 1974 is going to be a PIG with those heads. If you change em to something more modern.. even the limiting Vortechs.. (Not like some people run them after mods) you will actually generate some decent HP.

You have a decent block. And some of the parts are OK... but stock heads are going to waste your money.

 

Chris,

You built a 20b yet? And high boost engines?

Tony

 

They are stock heads, but not from the 1978 engine. They're non-smog heads, 1971 I believe, 1.94/1.5, with some mild port matching and polishing work, I can't remember the casting, but they were used on older Camaro/Vettes until the the double humps released (or on lower models, can't remember), and have a problem with cracking around the exhaust valves, if you know what heads I'm talking about... The engine as it sits should be around the 350 hp range, going conservatively (but as always, never know until it's actually on a dyno. The cast pistons (which it does still have) will be in there through this winter, as I basically want to get the car sorted out with the conversion before I go to crazy on it. I will be throwing a 150 wet shot in it, maybe direct port, depends on my budget at the time. The setup I have currently is designed with a few things in mind, to spin to 6500 RPM (as the 4.10s make it pretty necessary) and to limit low end torque (to give me a prayer of getting traction). In the next year or so I'm planning on either a blow through turbo setup, or just giving up the stealthiness and putting a whipple charger sticking out the hood (won't go near roots, have one on my other car, too inefficient).

Regardless, my point of the post wasn't that I can beat a 905 HP rotary (if they can drive/tune worth a damn, and it's not a dyno queen, he should stomp me) but rather that the guy was full of B.S. My car, as it sits (well, running ) should tick of a mid 12 second pass with some decent traction, I'd like to see an 11 on spray. I don't think that's out of reach by any means.

Annnyway, sorry to get off topic. You made a lot of good points there, and trust me, I've seen those big mean 200 hp V8s.

'sides if it is slow, I'll get out my FWD family car, I KNOW it's in the 12s.

::edit::

It bugged me so I checked. Casting: 3927186, used on the 1969-1970 LT-1. I forget the flow numbers, but they peak around 400 N/A HP without port work, with my mild porting, they should be just fine for 425-450.

 

KK No Problemm..... You have obviously thought this through.. If I hav ethe time with the Hurricane coming through (I am in St. Pete, and the Eye is just on the other side of Tampa) I may run the numbers anyhow.. just for giggles.
Looks like you are headed in the right direction..... sept for the blow through turbo. Smack yourself in the forhead with a board if you seriously think of trying it. Been there.. blow through and draw through. Not fun.. just shoot yourself instead of messing with the tuning PITA that is.

 

It sounds to me like some teenager listing all of the most popular internet sport compact car wonder-mods. It would cost about $100,000 to build a car like this in the US, so I doubt that some guy just assembled it in his garage last week without anybody else noticing the project.

Next time you chat with him, let him know that I want to race him with my gull-wing RX-7 10AE cabriolet coupe with a 906hp car-ported Renesis 20B with J-Spec spark plugs and Motec exhaust.

To answer the question, yes, I think a bridge-ported 20B could make 900hp with a T51R SPL, race gas, and nitrous.

 

LOL, yeah I've heard about carbs and turbos, I am a massichist though ... If I do go that way I'll likely -have- to switch to a fuel injected setup, holley projection or a multiport setup, we'll see. I've always been a fan of getting blown, so I'll likely end up with a whipple anywho. If you do run the numbers, let me know how they come out. Mine were pulled from a few local friends that build SBCs and some conversations with CompCams, but obviously they're just speculation.

Good luck on the hurricane too, I've got family that way myself, hope everything comes out okay for ya.

 

The SPL Will make 905 HP, a car that i work on made 880 to the wheels with the kai, and the spl is a lot bigger, you dont need a 88 to make 1000hp, a 80 will get you well over 1000hp, now are you gunna make that much hp with a three rotor maybe not, but who knows people coming with crazy **** now a days, this forum is becoming very stupid, if someone was to come in here and just say they ran a 6 second pass and really did you'll get knocked, but then when abel or seguel runs it o than everyone believes all of a sudden

 

Thats cause 90 percent of the people in here post to hear themselves.. and have NO CLUE ABOUT ANYTHING other than what they see on the Fast and the Furious... OR read about in here..
Misinformation spawning more and more til the reality of things is sooo distorted people think that a 13B N/A will make 550HP Easy.

There are some REALLY smart people in here. There are also a lot of 15 year olds posting all day upping thier numbers talking smack and having never turned a wrench other than to change the oil.

 

well let that be cuz guess what, i didnt know jack **** about rotaries till i got to this site and meeting people off this site, now I'll bet you when im done with my FD I will be well in the mid 9s with power steering and A/C...lol and still cruising the streets. but let them tell them str8 up the answer to there question and get it over with . people not going to learn just seeing people posting stupid comments, im getting tired of scrolling down waiting to see where the first guy is going to put some knowledge to this post then i say forget it cuz its to long. so get to the point tell them the answers and no bullshit. excuse the language. Let them be 15 but when they get to my age 22 which im still young and they will learn ALOT. thats the point of the forum learning. And i thank this forum for that.

 

figured it was bs

 

to be honest with you i dont think its BS to get 905hp out of a 20b, maybe not with that turbo but with atleast a 80mm turbo with a .96 big frame back housing would do the job

 

There have been a couple of 900 plus rwhp 20B's. Now I've only seen one street legal one but that was with a Thumper Series turbo and on C16. Still, it's over 900 rwhp which is crazy on a 2600 lbs FD. Like I said this is possible but I don't think this kids FD does have that much power.

Mid 9 second street car? Jeebus man, that's rarefied territory. You'll have to send me a link to what you're doing to it, I'd like to see it. (not doubting you, just curious what it takes to hit those numbers and be able to keep it running at a stop light with a rotary).
