Default What do you think of this setup?

I'm working on a project Trans Am right now and I wanted to know what you guys thought about it and what its capability was. So here we go.

94 TA
T-56
355 with LE2 heads 12.4 compression
Cam is 236/246 592/592 107 LSA
LE ported Intake
LPP stepped headers to 3 inch TD no mufflers
Monoblade TB
EWP
38# injectors
255lph pump
1.6 rockers
MSD pro billet opti
NGK plugs
Taylor wires
Spec 3 clutch with billet steel flywheel
Aluminum DS
Lots of suspension
4.10 gear 10 Bolt rear end

I'm hoping for somewhere between 400-425 RWHP and I'm thinking I could go deep in the 11's with some traction assuming the 10 bolt doesn't break. What do you guys think? Lloyd has helped out alot in putting everything together.
I may be forgetting something but off the top of my head that's what I remember.

Zach

Why not? Compression? It'll run just fine on 93. Been told by several people including Lloyd and the guys doing the work on the block.

We can get away with more due to our reverse flow cooling.

Haha I know what you mean about the 10 bolt. I'm going with it till it goes and in the meantime trying to save money for the 12 bolt.

Lloyd suggests the monoblade to get every last hp you can get. Plus I got it for a good price and it'll be put to good use if I ever get a more extensive build. I'd like to do a 383 or 396 with some trick flow heads later. It should help out then. But yes they still cost alot of money but they are such a nice piece.

Oh and Lloyd said because of the cam being it's size the compression NEEDS to be high to get the most out of it.

Yeah I would ask around. AI would definately know, so would Lloyd. I think AI says to get compression somewhere between 11.0 and 12.5 also with a big cam. Guys like Lloyd and AI know what works best and Lloyd told me with a cam this size high compression is a must.

And AI says the same thing about the monoblades and getting every last pony you can. Sure it costs money but what doesn't?

So, you're going to be making over 600hp n/a with a 200 shot to merit the need for that monoblade?

Who says you need an 800hp car to benifit from that? Lloyd and AI BOTH suggest one.

Consider the stock TB can support about 425hp N/A (a tad more with FI). If you figure 8.85hp per 2mm (1mm per bore), the 52/54/58 should support about 460/477/513hp, respectively. And I'm sure that those numbers are lower than what they can support since quite a few of the heavy hitters are running 52/58 TBs. I don't know if any of them run the monoblade, but when you're trying to squeeze out the most power you can, you are on a budget. The money saved by getting a 58mm could buy new springs, lighter/bigger valves, or go towards another component. But hey if you have the cash to burn, go right ahead heh

Well I'll listen to the experts on this one and if you're talking about saving money to spend on other things like valves or whatever but all that is taken care of. But just don't say things to belittle people for their decisions, that's what it sounds like you are doing. Besides they hold value very well and I got a good deal on it. This post was supposed to see what people thought this setup would do, not criticizing me for what I bought for the car.

I think the monoblade would be more in order if you were running le3's, a fully work intake, SR cam, and shaftmounts.

But since you already have one, try to get some work done to the heads and intake if llyod still has them, that wll help make a better difference. Your going to need lots of airflow to take advantage of it.

I think it should put down quite a bit more power than you think. 435rwhp+, if you get up to le3's 450,455rwhp.

As for the compression, thats a little high. Shoot for 12.1 or 11.8.1, if you wan to run pump gas. Your going to need a rearend if you want decent times out of it. Thats way too much power for a stock 10 bolt.

But it should be fun on the street. Goodluck.

Thanks man I'm hoping maybe it'll do a little better than I'm thinking. I can't do the LE3's bc of the bigger valves. I don't have the right pistons for them. My pistons have 4 valve reliefs instead of the 2 so I'm pretty sure there would be contact. Lloyd is the one who has basically set everything up. I told him I had the monoblade and he said that was good to have. He's the one who also suggested to get the compression that high. He still has the heads and intake.

I run 12.4:1 SCR on pump gas - no worries with the right cam and attention to detail in assembly.

The MB is a must to maximize the potential, but be aware that tuning is a bit tougher. Also with this is the intake tract - most CAI create vacuum at WOT in an efficient high performance engine.

I think it will make a good motor. That's a nice cam and with that CR you should make your goal + more with a good tune. No such thing as too big on a TB either, it can only help feed more air if the engine wants it. How long until you actually get everything together?

Then you've totally misunderstood me, which is fine In the post 2 below the one I'm quoting, you mentioned you already had the Mono when you asked Lloyd. So of course he'll say it's good to have, since you already had it! May I suggest you ask both of them now if they feel that you need it, or if a 52/58 would work just as well? Because I'm curious what they'd say then.

If I wanted to belittle you, trust me you'd know, as I'd be throwing out words like incompetence and ignorance. And you clearly are neither of those, as your setup is quite impressive and will be really fun to have. I feel your HP estimates are probably right on the money, not sure about it being BHP, but I think it'll make that at the flywheel no problem.

Sorry you felt I was attacking your intelligence, wasn't my intent. I just think that the monoblade is way overkill.

Sorry man it just kinda felt like you were saying I was stupid for buying one. I just got an email from Lloyd and he said the monoblade was going to help feed the motor with enough air as long as the intake setup was good as well.

Ulakovic: I don't know when I'll finally get everything together. I've got most of the parts but not all. I'm hoping within the next couple of months that it will be running.

I've heard that tuning can be hard with a monoblade but Bryan at PCMforless is pretty good at what he does. I'll have him do a base tune for me and if he ever comes down here again a dyno tune.
