Prior to mods below my best NA time with specs. of car listed in sig. below were: (back in November, 05)

0.567 - Reaction time
1.797 - 60 ft
5.148 - 330 ft
86.04 - MID MPH
7.988 - 660 ft
10.399 - 990 ft
106.38 - MPH
12.609 - 1/4 mile

Well, I recently fit to my 85 camaro below:

- elec. water pump (proform) & junkyard (european ford) electric
fan - to replace engine driven stock pieces
- S-10 pickup takeoff manual steering box to replace engine
driven power steering setup
- electric fuel pump (Holley Blue) - replace carter street mech.
pump
- Retained alternator v-belt moroso large underdrive pulley and
Canton road race underdrive crank pulleywith ALAN GROVE
COMPONENTS elec. w/pump alternator bracket - but alternator
not yet wired to energize

On Saturday 4th February, 06 - I got my new best NA time of 12.097 @ 112.78 (see slip below) amounts to a near .6 et gain

0.704 - Reaction time
1.736 - 60 ft
----- - 330 ft (no reading)
90.18 - MID MPH
7.728 - 660 ft
10.014 - 990 ft
112.78 - MPH
12.097 - 1/4 mile

Perhaps a combination of weight savings and hp savings of the crank - just waiting to try the juice next time around - to see if 10's are really on the cards

Rest of the night - I ran 12 sec. heads up class & won my first class race
Times were : -

12.316 @ 3.65 (660 was 7.787 @ 88.06) bye run
(dont know what happened there with clock mph at end)

12.259 @ 88.76 (660 was 7.591@90.54) braked early- opponent broke down mid track

12.442 @ 79.93 (660 was 7.629 @ 90.73)braked early - final - opponent red

So there are some gains to be had with these mods!!!

Cheers

 

very impressive. I know IHI posted how he dropped .5 in the quarter by doing similar changes.

 

The electric water pump removed the power robbing belt driven pump. Converting to manual steering gained more hp by removing the power steering pump plus eliminated a bunch of weight off the car. Going to an electric fuel pump gained nothing unless your mechanical pump was defective. Cam driven pumps don't use enough hp to be measurable.

The ET increase is always nice but MPH is what indicates how much more power the engine is making. An increase of 6.4 mph is a big jump. That's an increase of about 50 hp of at least the equivalent of 50 hp since the car is a bit lighter now. There's no way you got that much with just a water pump and manual steering box conversion. I'd say the weather was also a contributer to your better times.

 

i'm also sure pulling off that water pump driven fan also free'd up a lot of horsepower, especially if the clutch was locked up on it.

 

Thanks for the replies

Weather ?? unusually cool (for us here) and rain threatened all day - so that was a factor

previous mechanical fuel pump was new but I just wonder if because it was the street version - if it may have been slightly laying down on supply at the high rpms

car throughout the day felt unusually strong in 3rd gear - and on my best pass my 6000rpm shift light ( I use it as a guide really) was on as I passed the 1000ft marker

Usually I am on a slow but purposeful build up in 3rd gear

All in all, I think the car is now more fit for its purpose with the mods and it showed up on a good weather day

Thanks for all the help anyways on this board in convincing me to take on these mods

no turning back

 

That's what I was going to say. Something changed.

 

Weather could've played a role depending on DA, but having personally been in his shoes with the exact same mods and gaining .5 in ET and I cant remember how much of an increase in mph exactly but it did increase me into the triple digits finally. was running like 98-99mph and jumped to 102-104mph after the swap depending on weather.

It was a consistant gain of .5 which when the weather got cooler that fall actually increased to .8 from previous yrs best.

I was thinking at the time since the motor was an anemic 350hp set-up the gains really shined bright since anything taken off a low hp engine tends to "look" like more power gained than if you did the same mods to an already efficent running 500hp set-up.

Been here done this and glad to see my results were mimicked so I know I was'nt crazy LOL!! Cheap, simple, easy hp!!

 

Thanks IHI - you know I have been practically following your formula in your sig. - why reinvent the wheel ??

 

Kinda why I have that huge azzed sig so guys on a cheap budget can duplicate a package that actually works in the real world with no biased paid advertising like magazines tend to follow. It's not a crazy fast combo by any means, but it has been bullet proof, consistant, mild street manners and ability to run pwr brakes, plus just flat out works well enough to keep the majority of guys happy. I have no idea why, but many guys keep their stuff a "big secret" to what they're running. I've never understood why unless it's to cover up the fact the have a BBC that can only muster high 10 to low 11 second passes and is not real streetable..then I too would have to keep the stats to myself LOL!!

 

That's why I run my own domain showing everything about the car. I even still have the specs from my old 383 stroker on there so people can see what I had and how well it ran with nothing more than factory parts.

I'm not going to list every last detail about the car. Do you really want to know my plug gap or valve lash?

 

LOL, no need to know about your plug gap specs

Your the Mod. so if the sig is a problem, lemme know and you or I can delete it. I've got enough other stuff going I dont have the time to sit down and make another site for the car only, someday just not anytime soon

 

Guys - please leave everything as is - trust me - sigs like IHI and a lot of others on here save alot of little questions you would like to ask

and it helps to direct you to members who have already worked out certain things and are heading in the same direction you would like to go

Thanks

 

I would recommend only showing the sig when pertinent to the topic, and only once per thread.

I've personally not gone with electric fuel pump or water pump, although I did go (back) to electric fan last season. I've been amazed at progress with very minor, and often inexpensive or no-cost, changes.

When people say, "There's more in there," there typically is.

(I'll do the sig this one time. . . )

 

I hate overly long sigs and as five7 says, you only really need to show it once per thread. There's times when I do a simple reply to a thread, I don't even disply my sig. If the topic gets going and I have more comments to make, I'll display it in a follow up message.
