has anyone installed this package? i've heard good things about it and the reviews seem good. anyone? i have a 95 and that's what vette mag tested and got 350 at the crank.

 

Ask mr mojo that was his car they tested

 

ask Mojo

 

he loved it... right up until it spun a bearing...

 

how do i ask mr mojo? who is he.
sorry, i haven't been in this forum for a bit.

 

gee... Mr Mojo is the moderator here. you can PM him.

Give this thread some time, he will be around later today, I am almost sure of this.

BTW, the motor in question did blow up, but there is no way to blame the SLP package for this failure... it spun a bearing at 130k+ miles of very abusive driving.

 

thanks...like i said, it's been a bit for me in this forum. i'll wait.....mojo?

 

Just looking at the list of "goodies" on their site, it's a complete waste of money. Instead, get headers, a 52mm throttle body, and maybe a tune.

 

what kind of performance gain is that. i was thinking about a throttle body upgrade but don't know the results yet.

 

Same results as theirs......for much less, but I did get a custom tune for a very good deal of around $100 for the tune and $100 dyno time. Before that, I had a jet chip stage 2 that gave me almost the same numbers. I got a much better looking a/f and power curve from 4k rpm up with the custom tune. The jet chip was a little rich. I only have 291rwhp which is 330hp, the throttle body and headers were the main ingredient.

 

what equip did you get for that mod?

 

Brand? Madvet?

 

TPIS headers, don't recall where I got the TB. I think madvet prices are about the same as anywhere else for the TB though. Might as well get the TPIS TB though.

 

did you do the headers yourself? or a shop? cost? pain?

 

I paid a shop. Think it was a couple hundred or so, I don't recall cause they installed a short throw shifter at the same time. He did have to do some custom work. The TB came later with a different shop, he installed an elect water pump at the same time and ruined my optispark. I say the same time, but the TB was installed first. I drove and gteched the car for hp before he got to the water pump and it was night and day. I didn't even need to gtech it to tell the big difference the TB made. The elect water pump didn't really do anything. I'd think the TB would be an easy diy and I have the confidence these days to try. I did the stage 2 jetchip myself, lol, it added some good tq but only about 5hp. Seems like it was 20-30 ft lbs.

 

The car SLP used was indeed my car. I put about 3000 mile son it when they gave it back to me. I did blow the engine a few months ago, though it sounds like a spun bearing, I haven't tore it apart yet to verify.

I just got the engine home a week ago.

As for any gains with the setup. The biggest gain probably came from the 1.6 rockers.

They dynoed it with my Corsa, then their new exhaust and finally with the stock exhaust. The stock exhaust gave them 318 at the crank with teh stock rockers and stock exhaust manifolds. With their stuff in place, the Corsa and SLP exhaust came out to 350. There was no difference between the two exhausts.

The shortie headers don't do much, but they do look good. This was verified many years ago by Mr Mackey who was among the first to use any SLP stuff on his car(since he's best friends with Ed Hamburger).

Slp pretty much dropped the C4 market a few years ago and then last year decided that there still was a market for C4 stuff and no t many people catering to us, so they stepped up with this package.

The price isn't too out of line, but expect only about30 HP over stock(as they advertise). I never did get to take the car to the track. I was going to do it on SLP day, but it was cancelled.

All the SLP stuff is on the new engine(which isn't in the car yet) and unfortunately I don't have a baseline for the new engine, so making a fair comparison will be hard.

Me personally, I'd save for long tube headers over the shorty headers and the triple cone intake looks good, but I don't know for sure if any gain is realized with it. I've been told that there isn't.

They also put in a 160 thermostat and surely reprogrammed the fans to come on earlier. This is very noticeable because stock, the car will run at 190-210 and with the new t-stat, it barely got over 170 unless I was sitting in traffic and even then it stayed relatively cool.

 

I disagree with the 160* stat. 170* op temp is just too damned cold for modern engines.

 

I disagree as well, but when it's free who can complain? That would be good for the dragcar.

 

The higher temp from the factory is for better emissions, not performance or durability. Mine runs clean anyway with proper cats, and passes the dyno emissions test so screw it.

The difference shows up when I run the engine really hard, like an all out assault on the Dragon, 15 minutes of hard throttle in 2nd gear. With the 160 degree stat the oil temp only gets up to 230 or so and stays there. In summer traffic the water temp stabilizes at the setting of the fans, 195, instead of soaring to 230 +. I think my engine will live with the 160 t-stat. I only have 110K on it now so we'll see how long it actually lasts.

The engine does make more power at the lower temp.

 

mojo, thanks for the reply. sounds like i may go with either the rockers or the TB for now. i'll wait 'till what i see in carlisle in a month. i agree the slp intake looks good but for the price do you think there is a difference between that and say a green filter or k&n with a open lid?
