Idle clip


I have some casual driving tuning issues to iron out but otherwise, it seems stupid fast compared to before.

No one cares. Yours is an M6 his is an A4 and you are in the LT section.

Good results OP, very healthy through a stalled auto.

That's cause LT1 owners are butthurt

Yeah, OP seems real butthurt with his results doesn't he? I remember trolling my first thread.

Very nice upgrades build similar to mine great results 343 rwhp is usable rpm range.

Dyno Jockeys also be crying for that extra 8hp at 6800 rpm not usable on the street.

My LS 360 rwhp very driveable and reliable.

Good work congratulation on using dyno as a tool for measurements.

i’ve destroyed my fair share of heads/cam ls1’s. Talk about butt hurt.

I like outrunning LS guys more than Ford guys.

I'm usually asked two questions by LS or car guys in general....Is it LS swapped and once they see its an LT1 its "how much nitrous you spraying?"

Nice car and numbers Epro!

TBH, I think it's the LS owners who get angry. It's not out of jealousy, I can't put my finger on it.

The 4th gen fbody is a funny car, it received basically all the great engines of the time (3.8 SII, LT1 and the LS1)

The 3.8 was the greatest V6 GM ever made and probably still is.

The LT1 was the most powerful and most advanced SBC ever made.

The LS1 was... the LS1. It coined the phrase "LS swap it".

If you choose to build a 4th gen and it's not an LS, people sure do get pissy.

We are not at all. I'd put good money on a solid 360 hp stalled auto LT1 destroying your grossly inflated cam only 408 rwhp dynoing car in the 1/4 mile. Your dyno is high and his is low because of the converter. With a locked converter his car would put down another 10-15 rwhp. You can tell it was either unlocked or downshifted when the rpms spiked then came back down when they laid into it.

I also think the traditional firing order sounds better. LS engines sound like crap and remind me of a crappy 2006 Chevy truck with the exhaust cut off which are all too common here. They drive around like their truck is fast too, slammed to the ground with obnoxious cutoff exhaust. I have schooled more than one of those trucks with my L31 383 and it is moving nearly 7,000 lbs.

LT1's definitely sound better than LS1's. If your car runs hard and turns good times that's great.

Any idea what RPM equates to 90mph and 125mph?

Crashm16

Personally I'm more impressed by the torque number and if you managed to keep the same curve as a stock LT1 that should be a ton of fun on the street.

I can't remember, is there something in the tune I could check to answer this for you?

Chris in Idaho

I'm not sure, I'm brand new to the LT1 and EFI game. I'm considering that same cam and was just curious how much torque converter it would take to get into that big solid torque curve you had.

I'm looking at the graph and I'm not smart enough to know what rpm range it is because the X axis is in MPH instead of RPM.

Close to the bottom of the page there is a gear/mph calculator that should be able to answer the question.

Chris in Idaho

What's your gear ratio? And I'm assuming the pull was done in 3rd gear 1:1?

Chris in Idaho

Here's what the online calculators are telling me. Assuming 1:1 transmission gear, 26" tires and 5% unlocked converter slippage.

With 3.23 gears the pull would have been roughly 3900-5500.

With 3.42 gears the pull would have been roughly 4200-5800.

Does that seem about right OP?

It would be cool to see what this cam did down closer to 3,000 but either way it's a pretty great looking torque curve.

Incidentally, I contacted Tick a few weeks ago and asked if they had dyno graphs of their various LT1 cams, or if they could tell me at what RPM the HM2 overtakes the HM1, and they did not have any info.

I would have thought a cam company would normally try their own cams?

Jonathon Atkins (previous owner of Tick) took a lot of the LT1 knowledge with him when he left.

You could try messaging him via his business page
