Well when my autuo shifts, I see 8-10 PSI. That is a spike of 1/2 PSI - 2 1/2 PSI.

Should I be concerned?

If I go to 9-10 PSI the it may spike @ 12 PSI and then :

Also sometimes I hit my rev limiter @ 6700 RPM while still in drive...

This can't be good, is there anything I can do to stop that? OTHER than a 5-spd swap.

 

Damn the boost spike is definetely not good, Ive been told it comes from the manual boost controller at times, certain ones do it really bad, some control it fairly well. Thats why everyone recommends Electronic ones.

The rev limiter I wouldnt be concerned with unless you know for a fact it is at 6700rpm. When Arthur dynoed the car, did he tell you how much your RPM was truly off? Because he usually has a more accurate reading than the analog gauge. Ive been told they are +/- 250rpm.

Really, the only way to deter boost spike is with the use of an electronic boost controller. On my Blitz SBC-ID, when I dial in 9 psi, it may spike to 9.2 psi, but that is because I have the gain set high (gain = how fast I want the boost to come). When I was using the manual boost controller you and I built, I saw a spike at 12 psi when I "thought" I was at 9. So, that was a BIG BIG no no. I immediately hooked up the Blitz and I have been fine ever since. Ask Jaime (Jay25) on how it sounds too lol......

But again, that is another 5 bills that you will have to fork out and waste.....

 

Baggs to be safe, it be best if you get a electronic one. I saw Erics electronic BC, and when I was next to him the car sounded like a freight train coming thru since the electronic controls the air by pulsating something like that and it keeps better control therefor you dont spike 2.5PSI. How ever I priced a few and they cost about $500 for a new one

 

thanks.. but no electroincs are planned...

too much money I'll work it out...

Oh well

dixit- I am guessing 6700 rpm

 

GET THE HALLMAN MANUAL BC!! Supposedly, it won't spike and for only $50?!?!?!

If you want incabin adjustability, then it's like $140-$180 I think.

 

damn automatics.. eric i readjusted my idle speed and my car drops to 500 at let off of full throttle, not even close to stalling out anymore.

boost controllers just get you in to trouble.

 

baggs...do you read me?

Get the Hallman ES manual BC for $50!!

I've heard nothing but good things from these guys...

 

I am only able to check the forums a little right now..lol

I am on it.. thanks for the info

 

Got Hallman yet?

 

no.. still waiting on my axles and the boost spike has yet to really scare me....

it may scare the **** outta me if I up the boost this weekend

But I am tyring to keeo the boost @ 8-9 PSI while I work on some new things
