Here in ohio we have only a dyno test, no underhood. I am leaning toward a well built, moderate boost motor, think it's possible?

BTW, I want an efi car, pref small block.

 

as a second thought, I just noticed the ramjet 502 is only 9.6:1 comp. Could a 9 psi ATI be adapted to this motor? (or would I need a 12psi b/c of all the extra cubes??) and put me where I'd want to be?

 

This plan also needs to incorporate some type of long block crate engine, I can do any metal fabbing and wiring that may be required, but I'd prefer to have a professionally built engine screaming underneath it..

You know,Whipple sells a complete motor/blower combo.A gm zz4 mtor and whipple blower.Lots of torque on pump gas,only its Carb sorry.

A ramjet could be the ticket,probably NOS would be the way to go with that motor.

I would def use a blower instead of NOS, I wouldn't be driving the car that much but I want to have the power on tap when I need it.
I think a blown ramjet 502 might work very nicely..

 

10 second, emmisions legal, daily driven car?? You can build one no problem.. But you will need most likely around 25k to do it dependign on how much work you do yourself.

I helped build a 580RWHP dyno emmisions legal 383 LT1 car, that ran 11.29@129 on junk street tires..Easy 10s with slicks. But we used a state of the art Motec computer management system to get it to pass emmisions. Also you will need to upgrade the trans and rear to accomidate the extra power, and set up the susp to be able to hook all of the power. Also an entire new fuel system to suport the power also.. Cha Ching. It can be done, butit wil cost SERIOUS amounts of money.

 

That is some serious money. You have to use a centrifigual blower or turbo. Something that only comes on at high speed and load. If you use a roots or whipple you'll blow high numbers. Especially with a big block when they're measuring for a small block. After you get done with the suspension/chassis and solid motor/trans mounts you won't want to drive the car everyday. Having a sophisticated electronic spark/fuel management system is a must. Sounds like a fun idea though.

 

Just a thought,A TTA could easily do this.
Stock is 13.68(mine)
Tweaked stock stuff is around 11.70
PT-54 Turbo and MSD50# injectors is around 11.2
Add a front mount intercooler and some tuning and it should go high 10's.
Cost,
PT54 $700
MSD50's $500
CAS V2 front mount $1100
Tuning $FREE
Total $2300
Figure in a few hundred more for small parts like a fuel pump and there you have a high 10 second,25 mile per gallon,emmisions legal,true daily driver with out even removing the throttle body.

I know,I know,it's not a V8 but I don't care scince I'm faster than most of the V8's around here.Just figured I'd give you another option.

my '88 GTA twin turbo made 465 rwhp & 521 ft-lbs rwtq before i started the rebuild. it had a mild .440 lift cam and had dual cats & mufflers, and passed VA emissions in this configuration. although i never ran a 10 sec 1/4 in it, it definitely had the capability. i had some tuning issues and a cheap converter that would not let me get any boost on the line.

Sorry Mike,I was thinkin of your car but all these numbers get me mixed up

Well I dug this up ... trying to really get ahold of the whole emmisions thing . I have the BBS 650hp kit . They are refabbing me a set of headers so I can retain the smogg pump ( suxx I need it but ohhh well ) , they are swapping it to the passenger side header. I have to figure out how where I want the bungs put in for the A.I.R .



But what I am curious about is ...once all the hardware is all visually legal ( smog ****'s up here pull ya over ...and pop the hood ...and stick a probe up your tail pipe sometimes) So the setup HAS to be tight ( legal) . You guys think I can make a 165 ECM with an FMU and a Prominator pro .... pass the smog test if need be ? It will be around 6 psi for start . I JUST rebuilt this motor before I knew I was getting a turbo so the CR is wrong ( 9.74:1) so I am going to just be nice with boost for now .

Thanx all
D

 

I think my engine has the capacity to get in the 10's...... and it pass emission.......

/N.

 

Could you pass a visual as well ? Do you have all the smogg crap , etc ? I need to have all that . I am sure i could make a tune to make it pass a sniffer , etc . But it's the fact I need all the emmissions crap intact.

 

I'd be willing to bet my car will pass emissions if i installed a cat on it. And it cost under $12,000 all together to build(including the cost of the car, mint 92 formula)

 

i dont know how Canada is but if its as strict as say california, not even having all the air lines connected will pass a visual. the parts installed MUST have a CARB number to be emissions legal even. it doesnt matter if they help emissions to make it better than stock, if theres no CARB number its not legal. thats cali though so you may want to check with your local government first.

also, if you are gonna burn your own prom you dont need an FMU. the FMU is only a bandaid IMO because it adds fuel based on vacuum. whereas a properly tuned computer will add fuel based on load. if you are already planning on burning a prom then i would just skip the FMU.

and finally, your compression ratio is fine. theres this big myth on the internet that you are REQUIRED to run low compression with boost. that is untrue to an extent. yes it makes it more pump gas friendly, but you can run even a 10.5:1 or high compression ratio with maybe a higher octane pump gas (say 93 or so) and run some sort of alcohol injection setup to help combat detonation. but at around 9.5:1 you should be ok as long as you dont run a higher boost level. im not sure whose tuning it but if you are gonna run say a low boost and high boost setup where you have the ability up the boost whenever you want, i would start out kinda low with boost pressure and add more slowly and check for detonation. then tune accordingly.

as to the original poster, the short answer to this is no. it is IMPOSSIBLE. i say impossible because it cant truely be 100% emissions legal per Federal standards to make our cars run that fast. now i say this because NO turbo kit available for our cars (no the STS kit is not legal for our cars, only 4th gens thus far)is CARB legal. i think the only CARB legal supercharger is the Procharger P1SC and that will NOT push a full weight daily driver into the 10s. nitrous is not CARB legal (as far as i know, im not a big nitrous guy). and the CARB legal heads and cam setups arent good enough to make the power needed.

so the technical answer is no. you can probably pass emissions in most places with like a D1SC and a big inch engine or maybe a hidden nitrous setup. but other than that it wont run that fast CARB legal to my knowledge.

 

I know a couple of guys in CA that are emissions legal that runs low 11's but use nitrous

 

We don't need the carb numbers up here . Just anything that was origonal. As far as the FMU thing . I am running a MAF setup and havent really found anything definitive on a good tune ....for a Forced induction setup AND a MAF .... so I figured the FMU was a necessity for a starting point.

 

just a question. Thankfully my area has no emissions testings. But how would emissions laws apply to putting an ls7 into a thirdgen? Would you have to have the emissions equipment that were originally on the third gen or that which is supposed to go with an ls7?

 

depends where you are .... can;t say for sure. But up here it would put you in a "hotrod"class and make you pass 1980 standsards if the engine was not an option for the car.


Think I got it right . ( PS ...maybe make a topic about it )
