Hi everyone. I have a stocked block TT setup that I am very pleased with. Over the winter time while my baby is away for the winter I try to buy some goodies for it to instal in the spring when it comes out. I am considering a HKS DLI this winter. I have asked several people who have spent thier hard earned money on them about what the benifits are after installation and I never seem to get a straight answer! Flat out can difference be felt or even noticed after this upgrade is installed???? Does the hotter spark cause better fuel mileage or anything that would warrant the money spent for it? Anyone out there that has bought and installed this please chime in? Thanks

 

if you are going to anything with the spark, the Kennebelle boost-a-spark is the only product worthwhile.

but you are soo faraway from needing anything to prevent spark blowout/ create a bigger spark.
It's just a waste a money for you.

 

The feedback I have gotten from 3 people that have/had the unit is that it was a waste for their cars. Just my

 

this, unless you run a UTEC you shouldn't have any issues with spark

 

I do have a UTEC.

 

ok, does your power fall off HARD after 5500rpm? If you're making what your sig says you make, you should be just fine.

I didn't run into issues with the UTEC until I got around 500whp @ 14psi on my APS TT kit.

 

This link shows my dyno graph.

I dont have that issue. I did have an issue with the Greddy blue though. Thats the main reason I went with a UTEC.

 

Based on that dyno, you are TOTALLY fine. Any added spark at this point would be a waste of money. If and when it does become an issue the Kenne Bell Boost-A-Spark is the way to go...I picked up 90whp at redline by adding it to my setup.

 

Thanks briguymax. I never heard of that before.

 

here's a good read....

I asked a couple of tuners the same question and flat out they both said no. If anything I was told they are more trouble than they are worth.

 

Short answer: No.

We are not using them on 1000+hp builds and getting along just fine. If you are at the point of needing greater spark you should have already invested in better engine management, such as Haltech, giving you control of dwell time.

There have been multiple occasions where we have actually removed HKS DLIs from Zs due to problems.

 

Im going against the waves here, and going to say that it isnt NEEDED, and for most isnt WORTH IT, but for me, and what it did for me, it proved worthwhile.

My stock block car felt crisper in its throttle response, and my top end "felt" improved.

Then I went to the track and trapped 2mph higher with the same setup/boost as before, and I did it in temps that were 40 degrees warmer than my previous best at the time.

I have since disconnected it a few times to see if I "FELT" a difference and I personally did and reconnected it.

Dont rush out to buy one, but if you have the means I wouldnt say no to it.

 

Stronger spark w/ a KB BAS and it's much cheaper.

 

I dont know enough about the KB to assess which one does its job better, I only know and share what I have experience with Bri...

 

I know, I'm just saying I've got dyno evidence of how profound an effect the BAS can have on a car that has spark issues, and it's only a hair over $200.

 

+1. Ask Hal how he replaced Q16 with VP Import and the Stock ignition did just fine without changing the map

 

I dont rec it or not rec it either as i have no pro's or con's since i installed mine over 4 years ago......and i still havent had a problem with it.
