Built motor

I what all is considered a built motor. My friend has been warning me if I throw a kenne bell or a whipple on my stock block that it might only last one time down the track or could even blow on the dyno. I know this might be a slight exaggeration but to be on the safe side I was thinking I would build up the bottom end. So what all do I need.

Re: Built motor

I'm going to let someone else get into all the details on Built motors, But on a stock motor, you can run a Kenne Bell or etc. What you have to make sure is that you DO NOT run High Boost on it, low numbers like 11 on down is fine, anything Higher, you stand the chance of Blowing Engine.

Re: Built motor

The numbers seem to be between 400hp and 450hp as to the strength of the bottom end of a stock motor. There are some posts of people running in the mid to upper 400's and have not had a problem. So low boost is safe. After that I guess you're talking 4 bolt mains, forged crank, etc.

Personally I don't think I'd risk dropping $7k on a SC and risk blowing the motor with high boost.

Re: Built motor

ok. so as long as i keep it conservative and keep it low to mid 400's then i should be ok. my buddy has a lightning and i think he just doesn't want me to be faster than him. lol. also does anyone know about the kenne bell superchargers. can the 2.6 be upgraded to the 2.8? the only difference i see is the inlet size.

I don't think you need to go up to 2.8. The Stage I kit goes from 9-19 psi. You can still add the 130mm throttle body for the Stage II kit later. The Stage I kit is over 500 RWHP, but thats taking to about 6600rpm at 8.5 psi. If you keep it below 6,000, you should be fine. That's to the wheels, which is an over 200hp increase.

Not to be a jerk to the OP but work on your driving your should be a whole second faster then your running now and if you do that there's your "supercharger"

I lost a whole bunch of low end torque when I did the intake manifold without heads and cams as suggested. Also I am using an email tune at the moment. I'm going to do a few dyno pulls and see what they say. I will take a video. There is a noticeable acceleration difference starting at 4000 rpm. And it's not the butterfly valves because the ford racing intake manifold doesn't have them.

But I see what you are saying. I would just like to be sure it isn't something with the tune or set up before I beat myself up over my driving. I've already been doing that. Lol

Yeah I have 4.10's

---------- Post added at 06:12 PM ---------- Previous post was at 06:07 PM ----------

I Ran a 14.1 with nothing but a k&n fipk intake last year. Now I have 4.10 gears, jlt series 3 cai, bbk twin 62 tb, ford racing intake manifold, under drive pulleys, o/r xpipe, dr's, short throw shifter, an email tune. With all that I am still struggling to get out of 14's. Just a little frustrated. I do want to get cams and polished ported heads. Maybe I will do that before a sc.

The TB and intake may be hurting you. You may have hurt the bottom end and torque that it's killing your launch. What's your 60'? Basohol ran in the low 13's I think, with half of what you got. I think heads are a waste for the $$. I may be wrong , but doesn't OR pipe hurt low torque as well?

The gears should make up for a lot. It might be your email tune. Maybe you should get a dyno and then have them tune it. You have enough changes to justify a dyno tune, that an email tune may not be set for. Should be worth it before dropping 6-7K.

Ok. That's probably what I'm going to do. I want to get some cams before I get a dyno. That way I don't have to get another.

Cams also hurt your low end power haha

Brenspeed cams claim no lose to your low end power

Brenspeed claims to have designed a cam that increases HP without loss of torque and still sounds badass. I want to get a set of these.

Unless you do all three (H/C/I), any one is a waste of money. Same as putting a Cai on that don't need a tune. IMO

Agreed on Heads and Intake, but I believe you can get 30HP out of cams. The heads seem to only give about 20HP and therefore $2k is tough to justify. Intake only seems to hurt torque with the removal of the CMDP plates, with no other mods.

But a CAI without a tune is still helpful. The stock filter box is very restrictive. A CAI that requires a tune is certainly better.

The stock heads are pretty good when reworked. All I'm saying is when 30 HP is not enough, and you do the rest, the cam that works now is not gonna be the best choice when you do. Thus wasting $ I've been told Ernie Elliot reworks our heads. Idk

It's hard to split it all up, especially if you may go SC later on.

Just a quick note if you do supercharge it make sure you put your stock pulleys on and not the underdrive ones otherwise you're gonna have a bad time lol and I run the Saleen supercharger with mine and built my engine as well and IMO I would build the engine anyway cause you have 90K and if you put more power to it, their is a good chance it might blow and now you have to get it re built and spend more money, if it wasn't for he mileage I would say go for it but with 90K time isn't on your side.
