306ci YS-trim 450fhp?

Hello there, i was just wondering if you think this YS-trim is too big for what i want. i already have the s/c. i have 306ci with gt40 cast iron heads, e303 cam with 1.72rr's, long tube headers, gt40 upper and lower intake 65mm TB and 75mm pro-m MAF. i want around 450hp with this s/c. will i be able to do that.. i still need to get pistons so i havent figured out what the c/r is going to be yet. Will i even get this s/c to produce that low of boost and how much boost and compression u think i need to produce 450hp out of this combo?? im gonna have to get a chip too

The YS will be on holiday making this kind of power but in my opinion this is a good thing.

so u think i will be able to use it?? someone told me i couldnt get the boost low enuff with that thing..lowest it will go is like 16psi..i duno.....like its not good for my combo or something
:confused:

i plan on running the YSI on even a smaller less pissed off motor the stock pulleys i think make around 16 psi ? im sure you could get a smaller 8 rib crank pulley to make less boost ? im gonna try the ysi with cometic head gaskets and mucho boost on a stock headed stock long block deal
ill let you know what happends

Actually you can order a pulley off ian to slow the blower if you need to. You can order what ever size you need.

so...the blower will work or not??? or will i see it kicking in only at higher rpms? i can actually get it to like 8lbs? maybe 10 whatever i need to get 450hp...

It will work, but may not be producing the best numbers compared to a smaller blower. usually your low end will suffer. I ran the 8" and 3" pullies the YSI came with on a 351 and made 16 psi at 6,000RPM. You could use a 3.33 pulley to slow it down. It will work just not the best. But if you have it use it.
Plus the YS is less agressive than the YSI. GO FOR IT.

I have hyper pistons and two bolt main and am running 20 psi with a conservative tune and thus far all seems well. Not i have a good fuel system. All weldon, 60 injectors and ss lines.

You should be fine with your setup and 14-16 psi with 3.33 pulley.

yeah but wouldnt that give me more than 450hp...i pretty much have stock bottom end except for forged pistons and some stronger rods. so i dont want to go much past that.

DUDE you will be good to go with the extra power. I have a sportsman motor with all stock internals except for the Lunati cam. Hyper pistons and two bolt main. I am maiking 670's rwhp, made 530'srwhp on the s-trim for 3 years before. All is good.

I just put my BTM at 3 on the street and turn it up at the track. I have a conservative tune so as not to squeze every last drop of power out and detonate a piston. If you have forged pistons, run the 3" pulley get hi 500's rwhp with a conservative tune and you will be making the power for a long time to come on the motor.

on a stock bottom end? except for pistons. what rpms u think it will boost up at? i dont have anyone to tune it over here.. all i can do is get a chipp burned.

did i mention this is my daily driver on pump gas 93 octane. what c/r?

Yup 100%, remember, the blower isn't making any power if your foot is not in it.
So you will be putting around town making 150-200 hp normally. The big power won't come untill 4,500 and up. I still get ~13-14miles/ gallon with my foot in it 50% of the time. The beauty of a blower. The psi was 16 at 6,000 RPM.

Keep you shift point 6,000 ish at the track and you should be fine. Keep your shift point on the street in the 5,000 RPM range. I put mine at 5,400 and rev limiter at 6,000.

Again the blower is bigger than you need but you got so use it. Unlesss you can sell it for an S-trim and make a few bucks. But sooner or later you will want the bigger power.

yeah i need something that will come in lower rpms....i will probably be shifting at 5500-6000

i make 300fhp on motor just alone :P

You'll be good to go. Keep me informed, or ask me with any more questions. It is tough if you don't have some buddies who really know what is going on. I am fortunate to have a gruop of friends who have been doing this longer than me. A few of them are running in the mid and low 8's. One bud is 8.50's on Drag Radials. A few others in the 10's 11's and up.

Keep me informed on your progress.

Steve

what should my c/r be?

8.5-9.0:1

how much hp will 14-16psi make? estimate

put it on and find out! Start low and work your way up. There's so many variables it's immposible to say how much you'll make.

well i dont want to put on too much or it will go boom :( i think like 8-10 is all i need but i dont think u can get it to put out that low a ys-trim can u?

I would say 14 -16 psi on your motor tuned with 93 and easy on the timing should put you at 525-550 ish rwhp.

If you want lower boost 6.87 and 3.15 pulley or 8" and 3.33 pulley will do it. Also no belt slippage issues with the big SC pulley.

I cant remember but i thought it was 501 with the s trim on that big 351 not 530

how do you expect someone to make that kind of horse power on 93 if you cant do it on 104 with 13 pounds of boost with a 351

The 501 rwhp was on a MD. and S-trim. These usually read lower than a dyno jet. GT40 is looking to run a YS which should make those numbers.

I am making 670's rwhp at 20 psi (630's @16psi) with mine so 525-550rwhp should be do-able with 12-14 psi on his motor and a YS with a conservative tune. (Dyno Jet) Se my images I uploaded them.

Anyway, also it is possible to do it with an s-trim. Some of my past post for s-trim questions I gave info on my buddies setup that I sold my s-trim to (8 rib belt no cog either). He has a 302 holley intake and heads tune on 110 and made 530 rwhp on a dyno jet with no inner/after cooler. Put a cooler on there and a degree or more of timing and 550+rwhp should happen.

The main advantage of the 351 is usually torque though not necassarily HP.

Personally both the ys is to big for his combo hell the ysi is to big for your combo. he will make much better power with the s or t

Totally agree, but if you got it why try to sell it and replace with something smaller. Maybe not better power--top end, but definitly low end. This is why I am looking to see some T-trim dyno sheets on 302 or 351. So I know, maybe it is worth me trading a YSI for a T if the low end is better, but I don't think it is that much better. Want to see.

It will work for what he wants. Not the most effecient way.

I on the other hand was going to go with the T-trim, however, to buy the T-trim in pieces (head unit, braket, distube, bypass elbow etc.) don't need all the ignition and fuel since I already had an s-trim, would have spent more to get the T-trim. And i didn't want to go throuth the headache of selling all the misc parts if I bought the T-trim kit. I could by the YSi reengade kit and get the exact parts I needed for less money that peicing the T-trim together. Also I was able to sell my S-trim to a buddy and heonly needed the head unit, bracket , dis and bypass. Worked out.

I think the ysi is too big.......but not for Blownby....

ya but u dont need a ysi to go 11"s like gotblownby

I agree again.....Seems like the Renegade YSI setup is about the same price as the Regular T-Trim setup though.......

Nope you can do it on an A-trim. I have a buddy that ran 11.60s (11.7x-11.8x consistently)on his 302 A-trim with full power sterring, ac, mechanical pump and fan. Trust me, I get a lot of #@!* from him since i only ran 11.20's with the s-trim and an extra 49 cubes. My issue is the TKO. I shift like Granny. Look at the pics of my car. It is not a Race Car. I dont power shift. This kills your boost between shifts. Rather a Street car with some Go.

Looking at the AOD next summer. I need some Bling Bling first. If I put an AOD in and times will improve dramatically.

However, I haven't got any times yet with the new setup. If I can get 10.6's - 10.80's with the TKO the AOD will put me in the high 9's.

YA THAT IS PRETTY SORRY MAYBE YOU SHOULD TRY THE A TRIM

What are your times, what is your setup, where are some pics?? Are you just here to bash? Last I looked the web site was superchargerHELP.com not superchargerBASH. com

Thanks for your CONSTRUCTIVE CRITISISM. I get it all the time. If it makes you feel better keep it coming,

I understand 11.20's with an S-trim is not the greatest, but look at my car, it is not a race car. These are respectable times for a five speed heavy full weight car. I just have fun racing a few times a summer and cruising the local car shows. For me it is a hooby not an addiction.

No hard feelings here, just wondering what's up? If I can help in any way let me know.:D

Remember for what I lack in click click I can make up in HP.

For what it's worth, BRING IT ON BABY.
